Roller chain
Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, printing presses, cars, motorcycles, and bicycles. It consists of a series of short cylindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket. It is a simple, reliable, and efficient[1] means of power transmission.

Though CHINAMFG Renold is credited with inventing the roller chain in 1880, sketches by Leonardo da Vinci in the 16th century show a chain with a roller bearing.

Construction of the chain
Two different sizes of roller chain, showing construction.
There are 2 types of links alternating in the bush roller chain. The first type is inner links, having 2 inner plates held together by 2 sleeves or bushings CHINAMFG which rotate 2 rollers. Inner links alternate with the second type, the outer links, consisting of 2 outer plates held together by pins passing through the bushings of the inner links. The “bushingless” roller chain is similar in operation though not in construction; instead of separate bushings or sleeves holding the inner plates together, the plate has a tube stamped into it protruding from the hole which serves the same purpose. This has the advantage of removing 1 step in assembly of the chain.

The roller chain design reduces friction compared to simpler designs, resulting in higher efficiency and less wear. The original power transmission chain varieties lacked rollers and bushings, with both the inner and outer plates held by pins which directly contacted the sprocket teeth; however this configuration exhibited extremely rapid wear of both the sprocket teeth, and the plates where they pivoted on the pins. This problem was partially solved by the development of bushed chains, with the pins holding the outer plates passing through bushings or sleeves connecting the inner plates. This distributed the wear over a greater area; however the teeth of the sprockets still wore more rapidly than is desirable, from the sliding friction against the bushings. The addition of rollers surrounding the bushing sleeves of the chain and provided rolling contact with the teeth of the sprockets resulting in excellent resistance to wear of both sprockets and chain as well. There is even very low friction, as long as the chain is sufficiently lubricated. Continuous, clean, lubrication of roller chains is of primary importance for efficient operation as well as correct tensioning.

Lubrication
Many driving chains (for example, in factory equipment, or driving a camshaft inside an internal combustion engine) operate in clean environments, and thus the wearing surfaces (that is, the pins and bushings) are safe from precipitation and airborne grit, many even in a sealed environment such as an oil bath. Some roller chains are designed to have o-rings built into the space between the outside link plate and the inside roller link plates. Chain manufacturers began to include this feature in 1971 after the application was invented by Joseph Montano while working for Whitney Chain of Hartford, Connecticut. O-rings were included as a way to improve lubrication to the links of power transmission chains, a service that is vitally important to extending their working life. These rubber fixtures form a barrier that holds factory applied lubricating grease inside the pin and bushing wear areas. Further, the rubber o-rings prevent dirt and other contaminants from entering inside the chain linkages, where such particles would otherwise cause significant wear.[citation needed]

There are also many chains that have to operate in dirty conditions, and for size or operational reasons cannot be sealed. Examples include chains on farm equipment, bicycles, and chain saws. These chains will necessarily have relatively high rates of wear, particularly when the operators are prepared to accept more friction, less efficiency, more noise and more frequent replacement as they neglect lubrication and adjustment.

Many oil-based lubricants attract dirt and other particles, eventually forming an CHINAMFG paste that will compound wear on chains. This problem can be circumvented by use of a “dry” PTFE spray, which forms a solid film after application and repels both particles and moisture.

Variants in design

Layout of a roller chain: 1. Outer plate, 2. Inner plate, 3. Pin, 4. Bushing, 5. Roller
If the chain is not being used for a high wear application (for instance if it is just transmitting motion from a hand-operated lever to a control shaft on a machine, or a sliding door on an oven), then 1 of the simpler types of chain may still be used. Conversely, where extra strength but the smooth drive of a smaller pitch is required, the chain may be “siamesed”; instead of just 2 rows of plates on the outer sides of the chain, there may be 3 (“duplex”), 4 (“triplex”), or more rows of plates running parallel, with bushings and rollers between each adjacent pair, and the same number of rows of teeth running in parallel on the sprockets to match. Timing chains on automotive engines, for example, typically have multiple rows of plates called strands.

Roller chain is made in several sizes, the most common American National Standards Institute (ANSI) standards being 40, 50, 60, and 80. The first digit(s) indicate the pitch of the chain in eighths of an inch, with the last digit being 0 for standard chain, 1 for lightweight chain, and 5 for bushed chain with no rollers. Thus, a chain with half-inch pitch would be a #40 while a #160 sprocket would have teeth spaced 2 inches apart, etc. Metric pitches are expressed in sixteenths of an inch; thus a metric #8 chain (08B-1) would be equivalent to an ANSI #40. Most roller chain is made from plain carbon or alloy steel, but stainless steel is used in food processing machinery or other places where lubrication is a problem, and nylon or brass are occasionally seen for the same reason.

Roller chain is ordinarily hooked up using a master link (also known as a connecting link), which typically has 1 pin held by a horseshoe clip rather than friction fit, allowing it to be inserted or removed with simple tools. Chain with a removable link or pin is also known as cottered chain, which allows the length of the chain to be adjusted. Half links (also known as offsets) are available and are used to increase the length of the chain by a single roller. Riveted roller chain has the master link (also known as a connecting link) “riveted” or mashed on the ends. These pins are made to be durable and are not removable.

Use

An example of 2 ‘ghost’ sprockets tensioning a triplex roller chain system
Roller chains are used in low- to mid-speed drives at around 600 to 800 feet per minute; however, at higher speeds, around 2,000 to 3,000 feet per minute, V-belts are normally used due to wear and noise issues.
A bicycle chain is a form of roller chain. Bicycle chains may have a master link, or may require a chain tool for removal and installation. A similar but larger and thus stronger chain is used on most motorcycles although it is sometimes replaced by either a toothed belt or a shaft drive, which offer lower noise level and fewer maintenance requirements.
The great majority of automobile engines use roller chains to drive the camshaft(s). Very high performance engines often use gear drive, and starting in the early 1960s toothed belts were used by some manufacturers.
Chains are also used in forklifts using hydraulic rams as a pulley to raise and lower the carriage; however, these chains are not considered roller chains, but are classified as lift or leaf chains.
Chainsaw cutting chains superficially resemble roller chains but are more closely related to leaf chains. They are driven by projecting drive links which also serve to locate the chain CHINAMFG the bar.

A perhaps unusual use of a pair of motorcycle chains is in the Harrier Jump Jet, where a chain drive from an air motor is used to rotate the movable engine nozzles, allowing them to be pointed downwards for hovering flight, or to the rear for normal CHINAMFG flight, a system known as Thrust vectoring.
 

Wear

The effect of wear on a roller chain is to increase the pitch (spacing of the links), causing the chain to grow longer. Note that this is due to wear at the pivoting pins and bushes, not from actual stretching of the metal (as does happen to some flexible steel components such as the hand-brake cable of a motor vehicle).

With modern chains it is unusual for a chain (other than that of a bicycle) to wear until it breaks, since a worn chain leads to the rapid onset of wear on the teeth of the sprockets, with ultimate failure being the loss of all the teeth on the sprocket. The sprockets (in particular the smaller of the two) suffer a grinding motion that puts a characteristic hook shape into the driven face of the teeth. (This effect is made worse by a chain improperly tensioned, but is unavoidable no matter what care is taken). The worn teeth (and chain) no longer provides smooth transmission of power and this may become evident from the noise, the vibration or (in car engines using a timing chain) the variation in ignition timing seen with a timing light. Both sprockets and chain should be replaced in these cases, since a new chain on worn sprockets will not last long. However, in less severe cases it may be possible to save the larger of the 2 sprockets, since it is always the smaller 1 that suffers the most wear. Only in very light-weight applications such as a bicycle, or in extreme cases of improper tension, will the chain normally jump off the sprockets.

The lengthening due to wear of a chain is calculated by the following formula:

{\displaystyle \%=((M-(S*P))/(S*P))*100}

 

M = the length of a number of links measured

S = the number of links measured

P = Pitch

In industry, it is usual to monitor the movement of the chain tensioner (whether manual or automatic) or the exact length of a drive chain (one rule of thumb is to replace a roller chain which has elongated 3% on an adjustable drive or 1.5% on a fixed-center drive). A simpler method, particularly suitable for the cycle or motorcycle user, is to attempt to pull the chain away from the larger of the 2 sprockets, whilst ensuring the chain is taut. Any significant movement (e.g. making it possible to see through a gap) probably indicates a chain worn up to and beyond the limit. Sprocket damage will result if the problem is ignored. Sprocket wear cancels this effect, and may mask chain wear.

Chain strength

The most common measure of roller chain’s strength is tensile strength. Tensile strength represents how much load a chain can withstand under a one-time load before breaking. Just as important as tensile strength is a chain’s fatigue strength. The critical factors in a chain’s fatigue strength is the quality of steel used to manufacture the chain, the heat treatment of the chain components, the quality of the pitch hole fabrication of the linkplates, and the type of shot plus the intensity of shot peen coverage on the linkplates. Other factors can include the thickness of the linkplates and the design (contour) of the linkplates. The rule of thumb for roller chain operating on a continuous drive is for the chain load to not exceed a mere 1/6 or 1/9 of the chain’s tensile strength, depending on the type of master links used (press-fit vs. slip-fit)[citation needed]. Roller chains operating on a continuous drive beyond these thresholds can and typically do fail prematurely via linkplate fatigue failure.

The standard minimum ultimate strength of the ANSI 29.1 steel chain is 12,500 x (pitch, in inches)2. X-ring and O-Ring chains greatly decrease wear by means of internal lubricants, increasing chain life. The internal lubrication is inserted by means of a vacuum when riveting the chain together.

Chain standards

Standards organizations (such as ANSI and ISO) maintain standards for design, dimensions, and interchangeability of transmission chains. For example, the following Table shows data from ANSI standard B29.1-2011 (Precision Power Transmission Roller Chains, Attachments, and Sprockets) developed by the American Society of Mechanical Engineers (ASME). See the references[8][9][10] for additional information.

ASME/ANSI B29.1-2011 Roller Chain Standard SizesSizePitchMaximum Roller DiameterMinimum Ultimate Tensile StrengthMeasuring Load25.

For mnemonic purposes, below is another presentation of key dimensions from the same standard, expressed in fractions of an inch (which was part of the thinking behind the choice of preferred numbers in the ANSI standard):

Notes:
1. The pitch is the distance between roller centers. The width is the distance between the link plates (i.e. slightly more than the roller width to allow for clearance).
2. The right-hand digit of the standard denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. The left-hand digit denotes the number of eighths of an inch that make up the pitch.
4. An “H” following the standard number denotes heavyweight chain. A hyphenated number following the standard number denotes double-strand (2), triple-strand (3), and so on. Thus 60H-3 denotes number 60 heavyweight triple-strand chain.
 A typical bicycle chain (for derailleur gears) uses narrow 1⁄2-inch-pitch chain. The width of the chain is variable, and does not affect the load capacity. The more sprockets at the rear wheel (historically 3-6, nowadays 7-12 sprockets), the narrower the chain. Chains are sold according to the number of speeds they are designed to work with, for example, “10 speed chain”. Hub gear or single speed bicycles use 1/2″ x 1/8″ chains, where 1/8″ refers to the maximum thickness of a sprocket that can be used with the chain.

Typically chains with parallel shaped links have an even number of links, with each narrow link followed by a broad one. Chains built up with a uniform type of link, narrow at 1 and broad at the other end, can be made with an odd number of links, which can be an advantage to adapt to a special chainwheel-distance; on the other side such a chain tends to be not so strong.

Roller chains made using ISO standard are sometimes called as isochains.

How does a bush chain contribute to overall system efficiency?

A bush chain contributes to overall system efficiency in several ways:

1. Power transmission: Bush chains are designed to efficiently transmit power from the driving source to the driven machinery or equipment. They have high tensile strength and can effectively transfer rotational motion, allowing for the efficient transfer of power from the motor or engine to the intended application.

2. Load-bearing capacity: Bush chains are capable of handling heavy loads and are designed to withstand the stresses associated with transmitting power in industrial applications. By efficiently transferring the load, they minimize power losses and reduce the need for additional components or systems.

3. Smooth and reliable operation: Bush chains are constructed with precision-engineered components that work together to provide smooth and reliable operation. They have low friction between the bushings and pins, reducing energy losses and minimizing wear and tear. This results in improved overall system efficiency.

4. Minimal maintenance requirements: Bush chains are designed to operate with minimal maintenance. They have self-lubricating capabilities, reducing the need for frequent lubrication. This not only saves time and resources but also ensures consistent performance and extends the chain’s lifespan.

5. Flexibility and adaptability: Bush chains can be customized and adapted to suit specific application requirements. They are available in various sizes, pitches, and configurations, allowing for easy integration into different systems. This flexibility enhances system efficiency by providing the optimal chain solution for the specific application.

Overall, a properly selected and maintained bush chain contributes to the overall efficiency of a system by minimizing power losses, reducing wear and tear, and providing reliable and smooth operation. It ensures effective power transmission and load-bearing capacity, resulting in improved productivity and reduced downtime.

bush chain

Can a bush chain be used in high-load applications?

Yes, bush chains are commonly used in high-load applications due to their robust design and ability to handle heavy loads. The construction of a bush chain allows it to transmit significant amounts of force and torque, making it suitable for demanding industrial applications.

Bush chains are designed with solid bushings and precision rollers that provide excellent load-carrying capacity. The bushings act as a bearing surface between the pins and the rollers, reducing friction and allowing for smooth rotation under high loads.

Furthermore, bush chains are available in various sizes and configurations to accommodate different load requirements. They are made from durable materials such as alloy steel or stainless steel, which further enhances their strength and load-bearing capabilities.

When selecting a bush chain for a high-load application, it is important to consider factors such as the anticipated load magnitude, operating conditions, and the desired safety margin. Proper lubrication and regular maintenance are also essential to ensure optimal performance and extend the service life of the bush chain in high-load applications.

Overall, bush chains are a reliable choice for transmitting high loads and are widely used in industries such as mining, construction, heavy machinery, and material handling.

WEAR

 

The effect of wear on a roller chain is to increase the pitch (spacing of the links), causing the chain to grow longer. Note that this is due to wear at the pivoting pins and bushes, not from actual stretching of the metal (as does happen to some flexible steel components such as the hand-brake cable of a motor vehicle).

Only in very light-weight applications such as a bicycle, or in extreme cases of improper tension, will the chain normally jump off the sprockets.

The lengthening due to wear of a chain is calculated by the following formula:

M = the length of a number of links measured

S = the number of links measured

P = Pitch

In industry, it is usual to monitor the movement of the chain tensioner (whether manual or automatic) or the exact length of a drive chain (one rule of thumb is to replace a roller chain which has elongated 3% on an adjustable drive or 1.5% on a fixed-center drive). A simpler method, particularly suitable for the cycle or motorcycle user, is to attempt to pull the chain away from the larger of the 2 sprockets, whilst ensuring the chain is taut. Any significant movement (e.g. making it possible to see through a gap) probably indicates a chain worn up to and beyond the limit. Sprocket damage will result if the problem is ignored. Sprocket wear cancels this effect, and may mask chain wear.

CHAIN STRENGTH

The most common measure of roller chain’s strength is tensile strength. Tensile strength represents how much load a chain can withstand under a one-time load before breaking. Just as important as tensile strength is a chain’s fatigue strength. The critical factors in a chain’s fatigue strength is the quality of steel used to manufacture the chain, the heat treatment of the chain components, the quality of the pitch hole fabrication of the linkplates, and the type of shot plus the intensity of shot peen coverage on the linkplates. Other factors can include the thickness of the linkplates and the design (contour) of the linkplates. The rule of thumb for roller chain operating on a continuous drive is for the chain load to not exceed a mere 1/6 or 1/9 of the chain’s tensile strength, depending on the type of master links used (press-fit vs. slip-fit)[citation needed]. Roller chains operating on a continuous drive beyond these thresholds can and typically do fail prematurely via linkplate fatigue failure.

The standard minimum ultimate strength of the ANSI 29.1 steel chain is 12,500 x (pitch, in inches)2. X-ring and O-Ring chains greatly decrease wear by means of internal lubricants, increasing chain life. The internal lubrication is inserted by means of a vacuum when riveting the chain together.

Notes:
1. The pitch is the distance between roller centers. The width is the distance between the link plates (i.e. slightly more than the roller width to allow for clearance).
2. The right-hand digit of the standard denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. The left-hand digit denotes the number of eighths of an inch that make up the pitch.
4. An “H” following the standard number denotes heavyweight chain. A hyphenated number following the standard number denotes double-strand (2), triple-strand (3), and so on. Thus 60H-3 denotes number 60 heavyweight triple-strand chain.
 A typical bicycle chain (for derailleur gears) uses narrow 1⁄2-inch-pitch chain. The width of the chain is variable, and does not affect the load capacity. The more sprockets at the rear wheel (historically 3-6, nowadays 7-12 sprockets), the narrower the chain. Chains are sold according to the number of speeds they are designed to work with, for example, “10 speed chain”. Hub gear or single speed bicycles use 1/2″ x 1/8″ chains, where 1/8″ refers to the maximum thickness of a sprocket that can be used with the chain.

Typically chains with parallel shaped links have an even number of links, with each narrow link followed by a broad one. Chains built up with a uniform type of link, narrow at 1 and broad at the other end, can be made with an odd number of links, which can be an advantage to adapt to a special chainwheel-distance; on the other side such a chain tends to be not so strong.

Roller chains made using ISO standard are sometimes called as isochains.

bush chain

Can a bush chain be used in continuous operation applications?

Yes, a bush chain can be used in continuous operation applications. Continuous operation refers to a scenario where the chain is constantly in motion without significant periods of rest.

Bush chains are designed to handle continuous operation and are commonly used in various industrial applications that require continuous power transmission or material handling. They are known for their durability, reliability, and ability to withstand prolonged use.

When selecting a bush chain for continuous operation, it is important to consider factors such as the chain’s load capacity, speed rating, lubrication requirements, and overall durability. It’s crucial to choose a chain that is specifically designed for continuous operation to ensure optimal performance and longevity.

Regular maintenance, including proper lubrication and periodic inspections, is essential to ensure the smooth operation and longevity of the bush chain in continuous applications. Following the manufacturer’s guidelines for maintenance and lubrication intervals is crucial to prevent premature wear and ensure reliable operation.

Overall, bush chains are well-suited for continuous operation applications and provide a reliable means of power transmission or material handling in various industries.

What are the common signs of wear and tear in a bush chain?

As a bush chain is subjected to regular use and stress, it can exhibit signs of wear and tear over time. Here are some common indicators to look out for:

1. Chain Elongation: One of the most apparent signs of wear in a bush chain is elongation. This occurs when the chain’s pitch increases due to the stretching of the bushings, resulting in a loose and elongated chain. Elongation can lead to improper engagement with the sprockets and affect the overall performance of the chain.

2. Pin and Bushing Wear: The pins and bushings of a bush chain experience friction and wear during operation. Excessive wear can be observed as grooves or significant flattening of the pin surfaces or bushing bores. This wear can lead to increased clearances, reduced chain strength, and compromised performance.

3. Plate Wear: The inner and outer plates of a bush chain can also exhibit signs of wear. This can include visible signs of erosion, thinning of the plates, or rough surfaces. Plate wear can affect the chain’s overall strength and increase the risk of failure.

4. Sprocket Wear: Wear on the teeth of the sprockets is another indication of chain wear. Excessive wear can result in irregular tooth profiles, tooth tip thinning, or significant tooth wear. Sprocket wear can lead to poor chain engagement, increased noise, and reduced efficiency.

5. Misalignment: Misalignment of the chain can cause uneven wear on the pins, bushings, and plates. Signs of misalignment include uneven wear patterns, abnormal noise during operation, and premature failure of the chain components.

6. Increased Noise and Vibration: Excessive wear in a bush chain can result in increased noise and vibration during operation. Unusual rattling, clanking, or grinding sounds may indicate worn-out components or poor chain engagement.

Regular inspection of the chain and being attentive to these signs of wear and tear is crucial. When any of these signs are noticed, it is recommended to take appropriate measures such as replacing the chain or repairing the worn components to ensure the safe and efficient operation of the equipment.

ROLLER CHAIN

Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, printing presses, cars, motorcycles, and bicycles. It consists of a series of short cylindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket. It is a simple, reliable, and efficient means of power transmission.

CONSTRUCTION OF THE CHAIN

Two different sizes of roller chain, showing construction.
There are 2 types of links alternating in the bush roller chain. The first type is inner links, having 2 inner plates held together by 2 sleeves or bushings CZPT which rotate 2 rollers. Inner links alternate with the second type, the outer links, consisting of 2 outer plates held together by pins passing through the bushings of the inner links. The “bushingless” roller chain is similar in operation though not in construction; instead of separate bushings or sleeves holding the inner plates together, the plate has a tube stamped into it protruding from the hole which serves the same purpose. This has the advantage of removing 1 step in assembly of the chain.

The roller chain design reduces friction compared to simpler designs, resulting in higher efficiency and less wear. The original power transmission chain varieties lacked rollers and bushings, with both the inner and outer plates held by pins which directly contacted the sprocket teeth; however this configuration exhibited extremely rapid wear of both the sprocket teeth, and the plates where they pivoted on the pins. This problem was partially solved by the development of bushed chains, with the pins holding the outer plates passing through bushings or sleeves connecting the inner plates. This distributed the wear over a greater area; however the teeth of the sprockets still wore more rapidly than is desirable, from the sliding friction against the bushings. The addition of rollers surrounding the bushing sleeves of the chain and provided rolling contact with the teeth of the sprockets resulting in excellent resistance to wear of both sprockets and chain as well. There is even very low friction, as long as the chain is sufficiently lubricated. Continuous, clean, lubrication of roller chains is of primary importance for efficient operation as well as correct tensioning.

LUBRICATION

Many driving chains (for example, in factory equipment, or driving a camshaft inside an internal combustion engine) operate in clean environments, and thus the wearing surfaces (that is, the pins and bushings) are safe from precipitation and airborne grit, many even in a sealed environment such as an oil bath. Some roller chains are designed to have o-rings built into the space between the outside link plate and the inside roller link plates. Chain manufacturers began to include this feature in 1971 after the application was invented by Joseph Montano while working for Whitney Chain of Hartford, Connecticut. O-rings were included as a way to improve lubrication to the links of power transmission chains, a service that is vitally important to extending their working life. These rubber fixtures form a barrier that holds factory applied lubricating grease inside the pin and bushing wear areas. Further, the rubber o-rings prevent dirt and other contaminants from entering inside the chain linkages, where such particles would otherwise cause significant wear.[citation needed]

There are also many chains that have to operate in dirty conditions, and for size or operational reasons cannot be sealed. Examples include chains on farm equipment, bicycles, and chain saws. These chains will necessarily have relatively high rates of wear, particularly when the operators are prepared to accept more friction, less efficiency, more noise and more frequent replacement as they neglect lubrication and adjustment.

Many oil-based lubricants attract dirt and other particles, eventually forming an CZPT paste that will compound wear on chains. This problem can be circumvented by use of a “dry” PTFE spray, which forms a solid film after application and repels both particles and moisture.

VARIANTS DESIGN

Layout of a roller chain: 1. Outer plate, 2. Inner plate, 3. Pin, 4. Bushing, 5. Roller
If the chain is not being used for a high wear application (for instance if it is just transmitting motion from a hand-operated lever to a control shaft on a machine, or a sliding door on an oven), then 1 of the simpler types of chain may still be used. Conversely, where extra strength but the smooth drive of a smaller pitch is required, the chain may be “siamesed”; instead of just 2 rows of plates on the outer sides of the chain, there may be 3 (“duplex”), 4 (“triplex”), or more rows of plates running parallel, with bushings and rollers between each adjacent pair, and the same number of rows of teeth running in parallel on the sprockets to match. Timing chains on automotive engines, for example, typically have multiple rows of plates called strands.

Roller chain is made in several sizes, the most common American National Standards Institute (ANSI) standards being 40, 50, 60, and 80. The first digit(s) indicate the pitch of the chain in eighths of an inch, with the last digit being 0 for standard chain, 1 for lightweight chain, and 5 for bushed chain with no rollers. Thus, a chain with half-inch pitch would be a #40 while a #160 sprocket would have teeth spaced 2 inches apart, etc. Metric pitches are expressed in sixteenths of an inch; thus a metric #8 chain (08B-1) would be equivalent to an ANSI #40. Most roller chain is made from plain carbon or alloy steel, but stainless steel is used in food processing machinery or other places where lubrication is a problem, and nylon or brass are occasionally seen for the same reason.

Roller chain is ordinarily hooked up using a master link (also known as a connecting link), which typically has 1 pin held by a horseshoe clip rather than friction fit, allowing it to be inserted or removed with simple tools. Chain with a removable link or pin is also known as cottered chain, which allows the length of the chain to be adjusted. Half links (also known as offsets) are available and are used to increase the length of the chain by a single roller. Riveted roller chain has the master link (also known as a connecting link) “riveted” or mashed on the ends. These pins are made to be durable and are not removable.

USE

An example of 2 ‘ghost’ sprockets tensioning a triplex roller chain system
Roller chains are used in low- to mid-speed drives at around 600 to 800 feet per minute; however, at higher speeds, around 2,000 to 3,000 feet per minute, V-belts are normally used due to wear and noise issues.
A bicycle chain is a form of roller chain. Bicycle chains may have a master link, or may require a chain tool for removal and installation. A similar but larger and thus stronger chain is used on most motorcycles although it is sometimes replaced by either a toothed belt or a shaft drive, which offer lower noise level and fewer maintenance requirements.
The great majority of automobile engines use roller chains to drive the camshaft(s). Very high performance engines often use gear drive, and starting in the early 1960s toothed belts were used by some manufacturers.
Chains are also used in forklifts using hydraulic rams as a pulley to raise and lower the carriage; however, these chains are not considered roller chains, but are classified as lift or leaf chains.
Chainsaw cutting chains superficially resemble roller chains but are more closely related to leaf chains. They are driven by projecting drive links which also serve to locate the chain CZPT the bar.

A perhaps unusual use of a pair of motorcycle chains is in the Harrier Jump Jet, where a chain drive from an air motor is used to rotate the movable engine nozzles, allowing them to be pointed downwards for hovering flight, or to the rear for normal CZPT flight, a system known as Thrust vectoring.

WEAR

 

The effect of wear on a roller chain is to increase the pitch (spacing of the links), causing the chain to grow longer. Note that this is due to wear at the pivoting pins and bushes, not from actual stretching of the metal (as does happen to some flexible steel components such as the hand-brake cable of a motor vehicle).

With modern chains it is unusual for a chain (other than that of a bicycle) to wear until it breaks, since a worn chain leads to the rapid onset of wear on the teeth of the sprockets, with ultimate failure being the loss of all the teeth on the sprocket. The sprockets (in particular the smaller of the two) suffer a grinding motion that puts a characteristic hook shape into the driven face of the teeth. (This effect is made worse by a chain improperly tensioned, but is unavoidable no matter what care is taken). The worn teeth (and chain) no longer provides smooth transmission of power and this may become evident from the noise, the vibration or (in car engines using a timing chain) the variation in ignition timing seen with a timing light. Both sprockets and chain should be replaced in these cases, since a new chain on worn sprockets will not last long. However, in less severe cases it may be possible to save the larger of the 2 sprockets, since it is always the smaller 1 that suffers the most wear. Only in very light-weight applications such as a bicycle, or in extreme cases of improper tension, will the chain normally jump off the sprockets.

The lengthening due to wear of a chain is calculated by the following formula:

M = the length of a number of links measured

S = the number of links measured

P = Pitch

In industry, it is usual to monitor the movement of the chain tensioner (whether manual or automatic) or the exact length of a drive chain (one rule of thumb is to replace a roller chain which has elongated 3% on an adjustable drive or 1.5% on a fixed-center drive). A simpler method, particularly suitable for the cycle or motorcycle user, is to attempt to pull the chain away from the larger of the 2 sprockets, whilst ensuring the chain is taut. Any significant movement (e.g. making it possible to see through a gap) probably indicates a chain worn up to and beyond the limit. Sprocket damage will result if the problem is ignored. Sprocket wear cancels this effect, and may mask chain wear.

CHAIN STRENGTH

The most common measure of roller chain’s strength is tensile strength. Tensile strength represents how much load a chain can withstand under a one-time load before breaking. Just as important as tensile strength is a chain’s fatigue strength. The critical factors in a chain’s fatigue strength is the quality of steel used to manufacture the chain, the heat treatment of the chain components, the quality of the pitch hole fabrication of the linkplates, and the type of shot plus the intensity of shot peen coverage on the linkplates. Other factors can include the thickness of the linkplates and the design (contour) of the linkplates. The rule of thumb for roller chain operating on a continuous drive is for the chain load to not exceed a mere 1/6 or 1/9 of the chain’s tensile strength, depending on the type of master links used (press-fit vs. slip-fit)[citation needed]. Roller chains operating on a continuous drive beyond these thresholds can and typically do fail prematurely via linkplate fatigue failure.

The standard minimum ultimate strength of the ANSI 29.1 steel chain is 12,500 x (pitch, in inches)2. X-ring and O-Ring chains greatly decrease wear by means of internal lubricants, increasing chain life. The internal lubrication is inserted by means of a vacuum when riveting the chain together.

bush chain

Can a bush chain be used in food processing industries?

Yes, bush chains can be used in food processing industries, provided that they meet certain criteria to ensure food safety and hygiene. When selecting a bush chain for food processing applications, several factors should be considered:

1. Material compatibility: The chain material should be food-grade and suitable for contact with food products. Stainless steel, particularly austenitic stainless steel grades like 304 and 316, is commonly used due to its corrosion resistance, durability, and ease of cleaning. These materials are non-toxic and do not contaminate the food.

2. Lubrication: In food processing applications, it is important to consider the lubrication requirements. Some bush chains are available with self-lubricating properties or require food-grade lubricants that are safe for incidental contact with food. This ensures that the lubrication used does not pose a risk of contamination.

3. Cleanability: The bush chain should be designed in a way that allows for easy cleaning and maintenance. Smooth surfaces, without crevices or hard-to-reach areas, are preferred to prevent the accumulation of food particles, bacteria, or other contaminants. The chain should also withstand frequent cleaning processes, including washdowns with cleaning solutions or high-pressure water.

4. FDA and regulatory compliance: It is important to ensure that the bush chain and associated components comply with relevant food safety regulations, such as those set by the FDA (Food and Drug Administration) in the United States or similar regulatory bodies in other countries. Compliance with these regulations helps to maintain food safety standards.

5. Sanitary design: The bush chain should adhere to sanitary design principles, which include features such as smooth surfaces, no exposed threads, and easy disassembly for cleaning. This helps prevent the growth of bacteria and ensures the chain can be effectively sanitized.

By considering these factors and selecting a bush chain that meets the specific requirements of the food processing industry, it is possible to use bush chains safely and effectively in various applications, including conveying, sorting, packaging, and processing of food products.

Can a bush chain be repaired or does it need to be replaced entirely?

When a bush chain is damaged or worn out, the extent of the damage will determine whether it can be repaired or needs to be replaced entirely. Here are the considerations:

1. Minor Damage: In some cases, minor damage to a bush chain can be repaired. This includes issues such as a few broken or worn-out bushings or pins. These components can be replaced individually without replacing the entire chain.

2. Extensive Damage: If the bush chain has extensive damage, such as multiple broken links, severe wear on multiple components, or damaged sprockets, it may be more cost-effective and efficient to replace the entire chain. Repairing such extensive damage can be time-consuming and may not guarantee the chain’s optimal performance.

3. Chain Length: The length of the chain also plays a role in determining whether it can be repaired. If the damaged section is localized and doesn’t affect the overall length significantly, it may be possible to repair or replace only the affected portion.

4. Age and Condition: The age and overall condition of the bush chain should also be considered. If the chain is already worn out, has undergone multiple repairs, or is nearing the end of its service life, it is generally recommended to replace it entirely to ensure reliable operation.

5. Cost Considerations: Finally, the cost of repair versus replacement should be evaluated. In some cases, the cost of repairs, including labor and replacement parts, may exceed the cost of a new chain. In such instances, it is more economical to replace the chain.

Ultimately, the decision to repair or replace a bush chain depends on the extent of the damage, the chain’s overall condition, and cost considerations. It is advisable to consult with a qualified professional or the chain manufacturer for an accurate assessment and recommendation.

Can a bush chain be used in high-speed applications?

Yes, bush chains can be used in high-speed applications, but there are certain considerations to keep in mind. While bush chains are known for their durability and strength, they may have limitations in terms of their maximum allowable speed due to factors such as centrifugal forces and dynamic loads.

The speed capability of a bush chain depends on several factors, including the chain design, material, lubrication, and operating conditions. It is important to select a bush chain that is specifically designed for high-speed applications and to follow the manufacturer’s recommendations regarding speed limits.

In high-speed applications, it is crucial to ensure proper chain tensioning and alignment to minimize vibration and reduce the risk of chain failure. Regular maintenance, including lubrication and inspection, is also essential to prevent premature wear and extend the service life of the chain.

Additionally, the selection of a suitable lubricant is important for high-speed bush chain applications. The lubricant should have excellent film strength and provide sufficient protection against wear and friction at high speeds. It is recommended to consult with the chain manufacturer or a lubrication specialist to determine the most suitable lubrication solution.

Overall, while bush chains can be used in high-speed applications, it is essential to consider the specific requirements and limitations of the application and to ensure proper maintenance and lubrication to achieve reliable and efficient operation.

bush chain

How do you calculate the required length of a bush chain?

The length of a bush chain is determined by the distance between the sprockets or pulleys it needs to span. To calculate the required length, you can follow these steps:

1. Measure the distance between the centers of the sprockets or pulleys where the bush chain will be installed. This is known as the “center distance.”

2. Determine the number of chain links required. The number of links depends on the pitch of the bush chain, which is the distance between adjacent pins. The pitch is typically specified by the chain manufacturer.

3. Divide the center distance by the pitch of the chain to calculate the number of chain links needed. Round up to the nearest whole number to ensure proper engagement of the chain with the sprockets.

4. Multiply the number of chain links by the pitch to obtain the actual length of the chain required.

Keep in mind that the calculated chain length is a starting point and may need to be adjusted during installation. It is recommended to provide some additional slack in the chain to accommodate any tensioning or adjustment requirements.

It’s important to refer to the manufacturer’s specifications and guidelines for the specific bush chain you are using, as different chain types and designs may have variations in calculating the required length.

What are the design considerations for a bush chain system?

When designing a bush chain system, several key considerations should be taken into account to ensure its reliable and efficient operation. These design considerations include:

1. Load capacity: Evaluate the expected loads that the bush chain system will need to handle. Consider the weight, size, and type of materials or products being conveyed or transmitted. Select a bush chain with a suitable load capacity to ensure it can withstand the required loads.

2. Speed and acceleration: Determine the desired operating speed and acceleration of the bush chain system. This will influence the selection of chain pitch, material, and lubrication requirements. Higher speeds may require additional considerations such as reduced friction or increased precision.

3. Environmental conditions: Evaluate the operating environment for the bush chain system. Consider factors such as temperature, humidity, dust, chemicals, and presence of corrosive or abrasive substances. Select a bush chain material and coating that can withstand the environmental conditions and resist corrosion or wear.

4. Space limitations: Assess the available space for the installation of the bush chain system. Consider the dimensions and layout of the equipment, conveyor, or transmission system. Ensure that there is sufficient clearance for the chain’s movement and that the system can be properly tensioned and aligned.

5. Alignment and tensioning: Proper tensioning and alignment are critical for the smooth operation of a bush chain system. Design the system to include tensioners, idler sprockets, or adjustable mounting options to facilitate easy tensioning and alignment adjustments.

6. Lubrication and maintenance: Determine the lubrication requirements of the bush chain system. Consider the frequency and method of lubrication, as well as any accessibility constraints for maintenance. Select a lubrication method that suits the application, such as manual lubrication, automatic lubrication systems, or self-lubricating bush chains.

7. Safety considerations: Ensure that the bush chain system is designed with appropriate safety measures. Incorporate guards, covers, or enclosures where necessary to prevent accidental contact with moving parts. Consider emergency stop systems and safety interlocks for the protection of personnel and equipment.

By carefully considering these design factors, a bush chain system can be optimized for performance, reliability, and longevity in a specific application or industry.

ROLLER CHAIN

Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, printing presses, cars, motorcycles, and bicycles. It consists of a series of short cylindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket. It is a simple, reliable, and efficient means of power transmission.

CONSTRUCTION OF THE CHAIN

Two different sizes of roller chain, showing construction.
There are 2 types of links alternating in the bush roller chain. The first type is inner links, having 2 inner plates held together by 2 sleeves or bushings CZPT which rotate 2 rollers. Inner links alternate with the second type, the outer links, consisting of 2 outer plates held together by pins passing through the bushings of the inner links. The “bushingless” roller chain is similar in operation though not in construction; instead of separate bushings or sleeves holding the inner plates together, the plate has a tube stamped into it protruding from the hole which serves the same purpose. This has the advantage of removing 1 step in assembly of the chain.

The roller chain design reduces friction compared to simpler designs, resulting in higher efficiency and less wear. The original power transmission chain varieties lacked rollers and bushings, with both the inner and outer plates held by pins which directly contacted the sprocket teeth; however this configuration exhibited extremely rapid wear of both the sprocket teeth, and the plates where they pivoted on the pins. This problem was partially solved by the development of bushed chains, with the pins holding the outer plates passing through bushings or sleeves connecting the inner plates. This distributed the wear over a greater area; however the teeth of the sprockets still wore more rapidly than is desirable, from the sliding friction against the bushings. The addition of rollers surrounding the bushing sleeves of the chain and provided rolling contact with the teeth of the sprockets resulting in excellent resistance to wear of both sprockets and chain as well. There is even very low friction, as long as the chain is sufficiently lubricated. Continuous, clean, lubrication of roller chains is of primary importance for efficient operation as well as correct tensioning.

LUBRICATION

Many driving chains (for example, in factory equipment, or driving a camshaft inside an internal combustion engine) operate in clean environments, and thus the wearing surfaces (that is, the pins and bushings) are safe from precipitation and airborne grit, many even in a sealed environment such as an oil bath. Some roller chains are designed to have o-rings built into the space between the outside link plate and the inside roller link plates. Chain manufacturers began to include this feature in 1971 after the application was invented by Joseph Montano while working for Whitney Chain of Hartford, Connecticut. O-rings were included as a way to improve lubrication to the links of power transmission chains, a service that is vitally important to extending their working life. These rubber fixtures form a barrier that holds factory applied lubricating grease inside the pin and bushing wear areas. Further, the rubber o-rings prevent dirt and other contaminants from entering inside the chain linkages, where such particles would otherwise cause significant wear.[citation needed]

There are also many chains that have to operate in dirty conditions, and for size or operational reasons cannot be sealed. Examples include chains on farm equipment, bicycles, and chain saws. These chains will necessarily have relatively high rates of wear, particularly when the operators are prepared to accept more friction, less efficiency, more noise and more frequent replacement as they neglect lubrication and adjustment.

Many oil-based lubricants attract dirt and other particles, eventually forming an CZPT paste that will compound wear on chains. This problem can be circumvented by use of a “dry” PTFE spray, which forms a solid film after application and repels both particles and moisture.

VARIANTS DESIGN

Layout of a roller chain: 1. Outer plate, 2. Inner plate, 3. Pin, 4. Bushing, 5. Roller
If the chain is not being used for a high wear application (for instance if it is just transmitting motion from a hand-operated lever to a control shaft on a machine, or a sliding door on an oven), then 1 of the simpler types of chain may still be used. Conversely, where extra strength but the smooth drive of a smaller pitch is required, the chain may be “siamesed”; instead of just 2 rows of plates on the outer sides of the chain, there may be 3 (“duplex”), 4 (“triplex”), or more rows of plates running parallel, with bushings and rollers between each adjacent pair, and the same number of rows of teeth running in parallel on the sprockets to match. Timing chains on automotive engines, for example, typically have multiple rows of plates called strands.

Roller chain is made in several sizes, the most common American National Standards Institute (ANSI) standards being 40, 50, 60, and 80. The first digit(s) indicate the pitch of the chain in eighths of an inch, with the last digit being 0 for standard chain, 1 for lightweight chain, and 5 for bushed chain with no rollers. Thus, a chain with half-inch pitch would be a #40 while a #160 sprocket would have teeth spaced 2 inches apart, etc. Metric pitches are expressed in sixteenths of an inch; thus a metric #8 chain (08B-1) would be equivalent to an ANSI #40. Most roller chain is made from plain carbon or alloy steel, but stainless steel is used in food processing machinery or other places where lubrication is a problem, and nylon or brass are occasionally seen for the same reason.

Roller chain is ordinarily hooked up using a master link (also known as a connecting link), which typically has 1 pin held by a horseshoe clip rather than friction fit, allowing it to be inserted or removed with simple tools. Chain with a removable link or pin is also known as cottered chain, which allows the length of the chain to be adjusted. Half links (also known as offsets) are available and are used to increase the length of the chain by a single roller. Riveted roller chain has the master link (also known as a connecting link) “riveted” or mashed on the ends. These pins are made to be durable and are not removable.

USE

An example of 2 ‘ghost’ sprockets tensioning a triplex roller chain system
Roller chains are used in low- to mid-speed drives at around 600 to 800 feet per minute; however, at higher speeds, around 2,000 to 3,000 feet per minute, V-belts are normally used due to wear and noise issues.
A bicycle chain is a form of roller chain. Bicycle chains may have a master link, or may require a chain tool for removal and installation. A similar but larger and thus stronger chain is used on most motorcycles although it is sometimes replaced by either a toothed belt or a shaft drive, which offer lower noise level and fewer maintenance requirements.
The great majority of automobile engines use roller chains to drive the camshaft(s). Very high performance engines often use gear drive, and starting in the early 1960s toothed belts were used by some manufacturers.
Chains are also used in forklifts using hydraulic rams as a pulley to raise and lower the carriage; however, these chains are not considered roller chains, but are classified as lift or leaf chains.
Chainsaw cutting chains superficially resemble roller chains but are more closely related to leaf chains. They are driven by projecting drive links which also serve to locate the chain CZPT the bar.

A perhaps unusual use of a pair of motorcycle chains is in the Harrier Jump Jet, where a chain drive from an air motor is used to rotate the movable engine nozzles, allowing them to be pointed downwards for hovering flight, or to the rear for normal CZPT flight, a system known as Thrust vectoring.

WEAR

 

The effect of wear on a roller chain is to increase the pitch (spacing of the links), causing the chain to grow longer. Note that this is due to wear at the pivoting pins and bushes, not from actual stretching of the metal (as does happen to some flexible steel components such as the hand-brake cable of a motor vehicle).

With modern chains it is unusual for a chain (other than that of a bicycle) to wear until it breaks, since a worn chain leads to the rapid onset of wear on the teeth of the sprockets, with ultimate failure being the loss of all the teeth on the sprocket. The sprockets (in particular the smaller of the two) suffer a grinding motion that puts a characteristic hook shape into the driven face of the teeth. (This effect is made worse by a chain improperly tensioned, but is unavoidable no matter what care is taken). The worn teeth (and chain) no longer provides smooth transmission of power and this may become evident from the noise, the vibration or (in car engines using a timing chain) the variation in ignition timing seen with a timing light. Both sprockets and chain should be replaced in these cases, since a new chain on worn sprockets will not last long. However, in less severe cases it may be possible to save the larger of the 2 sprockets, since it is always the smaller 1 that suffers the most wear. Only in very light-weight applications such as a bicycle, or in extreme cases of improper tension, will the chain normally jump off the sprockets.

The lengthening due to wear of a chain is calculated by the following formula:

M = the length of a number of links measured

S = the number of links measured

P = Pitch

In industry, it is usual to monitor the movement of the chain tensioner (whether manual or automatic) or the exact length of a drive chain (one rule of thumb is to replace a roller chain which has elongated 3% on an adjustable drive or 1.5% on a fixed-center drive). A simpler method, particularly suitable for the cycle or motorcycle user, is to attempt to pull the chain away from the larger of the 2 sprockets, whilst ensuring the chain is taut. Any significant movement (e.g. making it possible to see through a gap) probably indicates a chain worn up to and beyond the limit. Sprocket damage will result if the problem is ignored. Sprocket wear cancels this effect, and may mask chain wear.

CHAIN STRENGTH

The most common measure of roller chain’s strength is tensile strength. Tensile strength represents how much load a chain can withstand under a one-time load before breaking. Just as important as tensile strength is a chain’s fatigue strength. The critical factors in a chain’s fatigue strength is the quality of steel used to manufacture the chain, the heat treatment of the chain components, the quality of the pitch hole fabrication of the linkplates, and the type of shot plus the intensity of shot peen coverage on the linkplates. Other factors can include the thickness of the linkplates and the design (contour) of the linkplates. The rule of thumb for roller chain operating on a continuous drive is for the chain load to not exceed a mere 1/6 or 1/9 of the chain’s tensile strength, depending on the type of master links used (press-fit vs. slip-fit)[citation needed]. Roller chains operating on a continuous drive beyond these thresholds can and typically do fail prematurely via linkplate fatigue failure.

The standard minimum ultimate strength of the ANSI 29.1 steel chain is 12,500 x (pitch, in inches)2. X-ring and O-Ring chains greatly decrease wear by means of internal lubricants, increasing chain life. The internal lubrication is inserted by means of a vacuum when riveting the chain together.

CHAIN STHangZhouRDS

Standards organizations (such as ANSI and ISO) maintain standards for design, dimensions, and interchangeability of transmission chains. For example, the following Table shows data from ANSI standard B29.1-2011 (Precision Power Transmission Roller Chains, Attachments, and Sprockets) developed by the American Society of Mechanical Engineers (ASME). See the references[8][9][10] for additional information.

For mnemonic purposes, below is another presentation of key dimensions from the same standard, expressed in fractions of an inch (which was part of the thinking behind the choice of preferred numbers in the ANSI standard):

58 58 50 38
34 68 60 12
1 88 80 58

Notes:
1. The pitch is the distance between roller centers. The width is the distance between the link plates (i.e. slightly more than the roller width to allow for clearance).
2. The right-hand digit of the standard denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. The left-hand digit denotes the number of eighths of an inch that make up the pitch.
4. An “H” following the standard number denotes heavyweight chain. A hyphenated number following the standard number denotes double-strand (2), triple-strand (3), and so on. Thus 60H-3 denotes number 60 heavyweight triple-strand chain.
 A typical bicycle chain (for derailleur gears) uses narrow 1⁄2-inch-pitch chain. The width of the chain is variable, and does not affect the load capacity. The more sprockets at the rear wheel (historically 3-6, nowadays 7-12 sprockets), the narrower the chain. Chains are sold according to the number of speeds they are designed to work with, for example, “10 speed chain”. Hub gear or single speed bicycles use 1/2″ x 1/8″ chains, where 1/8″ refers to the maximum thickness of a sprocket that can be used with the chain.

Typically chains with parallel shaped links have an even number of links, with each narrow link followed by a broad one. Chains built up with a uniform type of link, narrow at 1 and broad at the other end, can be made with an odd number of links, which can be an advantage to adapt to a special chainwheel-distance; on the other side such a chain tends to be not so strong.

Roller chains made using ISO standard are sometimes called as isochains.

What are the common signs of wear and tear in a bush chain?

As a bush chain is subjected to regular use and stress, it can exhibit signs of wear and tear over time. Here are some common indicators to look out for:

1. Chain Elongation: One of the most apparent signs of wear in a bush chain is elongation. This occurs when the chain’s pitch increases due to the stretching of the bushings, resulting in a loose and elongated chain. Elongation can lead to improper engagement with the sprockets and affect the overall performance of the chain.

2. Pin and Bushing Wear: The pins and bushings of a bush chain experience friction and wear during operation. Excessive wear can be observed as grooves or significant flattening of the pin surfaces or bushing bores. This wear can lead to increased clearances, reduced chain strength, and compromised performance.

3. Plate Wear: The inner and outer plates of a bush chain can also exhibit signs of wear. This can include visible signs of erosion, thinning of the plates, or rough surfaces. Plate wear can affect the chain’s overall strength and increase the risk of failure.

4. Sprocket Wear: Wear on the teeth of the sprockets is another indication of chain wear. Excessive wear can result in irregular tooth profiles, tooth tip thinning, or significant tooth wear. Sprocket wear can lead to poor chain engagement, increased noise, and reduced efficiency.

5. Misalignment: Misalignment of the chain can cause uneven wear on the pins, bushings, and plates. Signs of misalignment include uneven wear patterns, abnormal noise during operation, and premature failure of the chain components.

6. Increased Noise and Vibration: Excessive wear in a bush chain can result in increased noise and vibration during operation. Unusual rattling, clanking, or grinding sounds may indicate worn-out components or poor chain engagement.

Regular inspection of the chain and being attentive to these signs of wear and tear is crucial. When any of these signs are noticed, it is recommended to take appropriate measures such as replacing the chain or repairing the worn components to ensure the safe and efficient operation of the equipment.

Roller Chain Basics

Before choosing the right roller chain for your machine, it is necessary to learn some basics. Learn about sprockets, tensile strength, pitch, and width. Read this article to learn more. It will help you make an informed decision. Getting the right product is critical, but it’s not always as simple as choosing a brand name. You need to choose a company that supports its products and provides good service.
chain

Roller sprocket

If you are planning to purchase roller sprockets for your application, you should first look at the various types available. Sprockets available for single-strand roller chains are manufactured by Boston Steel – Type B sprockets are drilled to size. They are available in 1/4, 3/8, 1/2, 5/8, 3/4 and 1″ pitch sizes.
The diameter of the sprocket is important when choosing the right sprocket for your application. Using a caliper to measure the diameter of a toothless plate is a good way to determine the exact size of the sprocket. A caliper is the diameter of a plate without teeth. On Type B and C sprockets, the hub diameter measures the thickness of the hub.
Another type of sprocket is the steel split sprocket, which is split in diameter. This type is easy to install and remove, and is held together by bolts in the hub. Typically, split sprockets have chain pitches ranging from 40 to 240 and bores ranging from 3/4″ to 6″. The split sprockets are designed with one pointing towards the ceiling and the other two parallel to the floor.
When shopping for sprockets, it is important to remember that they are designed specifically for a specific chain. All chains are manufactured to specific standards. In the United States, the most common standard is ANSI. The chain pitch is the distance between the center of each pin and the center of the next pin. In the US, the standard is always measured in eight-inch intervals.
In addition to sprocket size, sprocket pitch and the surface area also affect chain life. Unlike belt sprockets, which are made of forged steel, the teeth on roller sprockets are stamped from steel sheet or pressed from powdered metal. The harder the teeth, the longer the chain will last.

Roller chain pitch

The pitch of a roller chain is the distance between the sprocket and the pin. The smaller the thread pitch, the smaller the bushing wear. Generally speaking, the smaller the pitch, the longer the life of the chain. For best performance and longest life, manufacturers recommend a minimum chain pitch of 2% to 3%. Chain pitch is important to ensure proper performance, and the manufacturer recommends that you replace the chain when it reaches 2% to 3% of normal.
To determine the correct chain pitch for a particular chain, first determine the sprocket size and pitch. Pitch is the distance between pin centers, measured in 1/8 inch increments. The pin diameter of the chain is also important. If you’re not sure about the pin diameter of your chain, measure a few links to get a good average reading. Alternatively, use a caliper to measure the inside diameter of the sprocket and count the number of teeth.
When sizing a sprocket, measure the chain between the gears with a caliper and compare it to the measurements on the chain size chart. Make sure you have checked all the specs and checked the correct chain pitch. Then, choose the correct chain pitch for your needs. This is a critical step in choosing the right chain. So get the correct pitch for your roller chain. Correct pitch helps ensure maximum performance and safety.
To identify a specific type of roller chain, measure its tensile strength. This represents the amount of load the chain can withstand before breaking. Another key parameter to consider is fatigue strength. Chains with high fatigue strength are more resistant to rust and wear than chains with low fatigue strength. The numbers on the right in the standard numbering represent normal or light duty chains, while the numbers on the left represent the pitch of heavy-duty chains.
Double pitch roller chains are a variant of single pitch chains. They are manufactured according to ISO 606 and meet the same standards as single pitch chains. They are mainly used in applications with lower requirements for speed and power transmission. The plates of double pitch roller chains are also longer than single pitch chains. The double pitch drive series is also used for elevator and long conveyor drives. There are three main types of roller chains: single-pitch chains, double-pitch carriers, and oversized rollers.

Roller chain width

When buying a roller chain, one of the first decisions you must make is its width. To make this determination, you need to measure the overall width of the chain, the diameter, and the width of each roller. You must also know the height and thickness of the board. After taking these measurements, you can start shopping for the perfect roller chain. But before you buy a new chain, it’s important to know what to expect from the chain itself.
There are many different types of roller chains. These chains are available for ANSI and metric measurements. They come in single-stranded and double-stranded variants. They are usually used for power transmission. Other types include agricultural, automotive, conveyor, multi-strand, and four-strand chains. These charts also include a chart so you can easily see the exact size you need. Listed below are some of the benefits of buying a roller chain.
Roller diameter and pin diameter are important factors in choosing the correct chain width. The width of the chain is the nearest binary fraction of 5/8 of an inch. It should be at least half the thickness of the sprocket, and the plate thickness is one-eighth the width of the chain. Overweight chains are indicated with the suffix H. The pitch and width of the chain are determined by the working load and machine speed.
The outer links of the roller chain are called pin links. These pins are inserted into the bushings of the adjacent roller links. They are held in place by cotter pins. Pin links are usually pressed into the pins of heavy-duty chains. These pins are used to hold the rollers in place. However, these pin chains can reduce the power rating of roller chains by up to 20%.
The ANSI 29.1 Steel Chain Specification specifies a minimum pitch in inches and ultimate strength of 12,500 x pitch in inches. At the same time, the O-ring chain greatly reduces wear due to its lubricating effect. O-ring and X-ring chains contain a lubricant injected by vacuum when riveting the chain together. Transmission chains are tested and governed by standards bodies such as ANSI. In 2011, the American Society of Mechanical Engineers developed a standard for precision power transmission chains.
chain

Roller chain tensile strength

One of the most important indicators of roller chain strength is tensile strength. This measurement refers to the amount of load the chain can withstand before breaking. Another measure, called fatigue strength, refers to the maximum load a chain can withstand before it breaks. The strength of a roller chain depends on its size, the quality of the steel used in its construction, and the heat treatment. There are also differences in the types of shot peening used to treat steel, pitch holes, and link plates.
When choosing a roller chain, the workload is critical. This is the maximum load the chain can withstand before fatigue failure occurs. This measurement is critical because it helps determine the type of load applied to the chain. When deciding which roller chain to buy, be sure to consider the mechanical type and desired strength. Then, make sure it meets strength and load-carrying capacity requirements.
The ultimate tensile strength of a roller chain is based on the manufacturer’s recommended maximum tensile strength. However, the actual tensile strength may be higher or lower than this value. The working load limit of a roller chain can also be calculated by multiplying the chain diameter by the grade. The working load limit of a chain is the highest tension it can withstand before breaking. This value is usually expressed in points.
The maximum tensile strength of roller chains varies by chain type. The single-strand heavy chain has thick side plates for higher shock loads. Single strand heavy-duty roller chains, also known as “bushing” roller chains, are also available. Double-stranded heavy chains are structurally similar, but they have two layers of steel connected by pins that are nearly twice as strong as standard roller chains.
The tensile strength of a single-strand roller chain is approximately 500 tons. In comparison, a single-chain blockchain has a tensile strength of 900. The tensile strength of the two is similar, and it is not recommended to choose one or the other. Although steel and titanium chains are considered the strongest materials for roller chains, these materials are not magnetic.

What is a travel chain?

A drive chain is a wheeled system that transmits energy from one equipment to an additional. The push chain is generally an oval ring all around a corner or worm equipment. On the other hand, idler pulleys do not transmit energy and are not employed to transfer the chain. In some instances, drive chains can be utilized with idler pulleys to transportation objects. This permits the push chain to recover some power from the next equipment.

conveyor chain

There are many kinds of conveyor chains to select from. One particular kind is a closed joint chain. It is composed of the barrel and connecting rod, manufactured from a one casting and heat-handled for higher power and longevity. Conveyor chains generally have reduced working speeds and are normally produced of malleable iron. An additional kind of chain is the electricity transmission chain, which is employed to transmit mechanical energy. They characteristic successful lubrication and are more robust than typical conveyor chains.
Roller chain pitches can selection from 50 percent an inch to a third of an inch. They are available in metal and nickel-plated metal. They can be utilised with inline or staggered rollers and can be created with different pitch ranges. They can also have bushings between the chainplates or gaps amongst the teeth to boost their greatest spacing. When choosing a conveyor chain, keep in mind to correctly lubricate bearing surfaces to reduce power absorption, dress in, and corrosion. Mineral oils of medium viscosity are appropriate for regular functioning temperatures. SAE 20W50 is appropriate. Manufacturers also offer self-lubricating chains.
Conveyor chains are used in numerous industries. The automotive market has traditionally utilized these chains for bulk transportation. Their dependability and minimal price make them an outstanding choice for a variety of apps. CZPT Chains delivers stainless metal and CZPT conveyor chains to meet up with your special demands. If you’re in the marketplace for a new conveyor, don’t forget to store close to. CZPT Chain can help you find the excellent 1.
The regular drive model consists of an ASME/ANSI roller chain wrapped all around a pushed sprocket. It can also be configured for variable rpm. The equipment ratio in between the two elements determines the reduction or improve in pace. In some instances, answer chains can be employed. Roller chains are more effective. Then, there are answers for both situations. There are many sorts of conveyor chains to select from.
Conveyor chain pitch also performs an critical role in overall performance. The smaller the pitch of the chain, the more quickly it spins. On the other hand, a more compact pitch will demand a lot more teeth on the sprocket, which indicates more backlinks will be engaged for the duration of the movement. This smaller articulation angle also makes smoother motion. It also minimizes vibration. For that reason, CZPT Chains can be trustworthy for a extended time.

roller chain

The functionality of a push chain relies upon on how effectively it is taken care of and lubricated. Mindful consideration to detail is necessary when choosing a roller chain, which is 1 of the most crucial components in a generate chain. Its suitable lubrication and assembly will considerably have an effect on its dress in existence. Below are some essential suggestions to stick to when buying a roller chain:
The size of the generate chain should be picked in accordance to the sprockets employed. The huge sprocket should have at least twenty five enamel, and the small sprocket must have less teeth. The pitch of a push chain is the get in touch with angle amongst the chain and the sprocket. The smaller sized the sprocket, the more compact the get in touch with angle of the two components. Bigger sprockets are far better, but smaller sprockets must never ever have less teeth.
When buying a roller chain, be sure to consider the maximum pace of the small sprocket. This will figure out how considerably lubrication you need to have. Various lubrication systems have distinct specifications. Guide lubrication restrictions how a lot of toes for each minute the travel chain can run, while oil bath lubrication can get you up to 1100 ft/min. The only way to improve generate chain pace is to buy a pump lubrication program.
After you have the right length, you can determine if you need a new one. To do this you have to move the axis to evaluate the size. Once the duration is established, the generate chain need to be removed from the sprocket and measured utilizing the ANSI specified measuring load. You should also stick to protection suggestions when measuring your chain. If you want to improve the existence of your drive chain, be confident to adhere to these guidelines.
An additional critical thought is the variety of setting you function in. For apps that need to have to avoid rubbing metal rails, it is ideal to use a roller chain that can face up to a cleanse indoor atmosphere. Though roller chains are generally more sturdy, they need to be saved appropriately to stay away from corrosion. If you care about the surroundings, consider opting for double chain. Its sturdiness and reduced routine maintenance costs will make it a beneficial expense in your business.

closed pivot

Shut-end pivot drive chains are employed in a selection of apps. They are acknowledged for their durability, high strength, and lengthy lifestyle. They are available in a range of grades, like quality four hundred, grade 600, and quality 800 pivots, which can withstand the high forces necessary for certain applications. Enclosed pivot chains can be used to raise, pull, express and transfer large loads.
Course four hundred shut-conclude pivot chain characteristics one particular-piece solid offset hyperlink building. Steel pins link every link and are prevented from rotating by head stops. This design and style permits the pin to hook up inside the barrel without breaking. This variety of chain is the most frequently employed and has the optimum toughness. In addition to being incredibly resilient, it gives lengthy-long lasting functionality and clean operation.
An additional closed-end pivot conveyor chain travel is named a power push chain. These chains consist of barrels and links employed to transmit rotation from 1 shaft to another. The barrels of the shut-end pivot chains are created of steel, which allows them to run simply on the sprockets. Block generate chains are used for minimal-speed apps, but they can be noisy when the chain is in get in touch with with the sprockets.
The enclosed pivot generate chain has rollers on both finishes to reduce use. These chains are normally created of steel and can be utilised in locations the place substantial-pace energy transmission is needed. They are also available in heavy-duty versions. In contrast to other kinds of chains, steel pivot chains are developed for a range of programs. They are suitable for weighty-duty purposes and their open up barrel style makes it possible for for small contact with the pins in the barrel and the root of the sprocket.

Linear chain

CZPT is an essential portion of linear generate technological innovation. This kind of chain is capable of offering actual electrical power in tight spaces. Normally, loads are moved by pulling or pushing. CZPT can perform equally varieties of movements. They can drive and pull added masses. This type of chain can also be wound and saved in the magazine. It is a well-liked choice for small machine resources and many other makes use of.
Not like traditional mechanical chains, CZPT makes use of a drive-pull technique to go weighty objects. It is a rigid locking style that prevents kinking and allows the chain to transmit power without having bending. The CZPT is an outstanding choice for relocating massive masses and is specifically versatile in energy transmission. Nevertheless, CZPT is a lot more costly than classic travel chain options.
The service life of a linear chain relies upon on its style, content type and dimensions. You could want to purchase a great top quality chain, but it’s not needed in all cases. While outstanding high quality can prolong the daily life of the chain, it could not be required for lower-speed drives or really light shock loads. If you might be not working with substantial-velocity shock masses, you almost certainly do not need attributes like oil reservoirs or bushing grooves.
The size of the drive sprocket can have a significant effect on the total lifestyle of the linear chain. It establishes how quickly the chain can go and how a lot horsepower it can produce. An eleven-tooth chain will strike about fifty percent its rated pace, but only about thirty percent of its rated horsepower. You can lengthen the daily life of your linear chain by selecting a travel sprocket with a greater number of teeth. It is very best to pick a travel sprocket with a large variety of teeth, but make certain the quantity of teeth is even. This will make certain that your chain wear is evenly distributed.

Routine maintenance measures of industrial chain lifting chain!
one. The sprocket must be installed on the shaft and should not be skewed or swayed. In the same transmission assembly, the finish faces of the two sprockets need to be on the exact same aircraft. When the heart length of the sprocket is less than .5m, the allowable deviation is 1mm when the center length of the sprocket is a lot more substantial than .5m, the permissible deviation is 2mm. Nevertheless, no friction is authorized on the sprocket aspect. If the knitting action of the two laps is also massive, it is easy to trigger de-chaining and accelerated wear. Verify and modify offset when changing sprockets.
2. The tightness of the lifting chain should be suitable. As well tight will enhance power intake, and the bearings are inclined to use. The tightness of the chain is: carry or compress from the middle of the chain, and the centre distance among the two sprockets is about 2%-3%.
three. The new lifting chain is also prolonged or stretched following use, and it is challenging to modify. Get rid of backlinks as needed, but should be an even quantity. The hyperlinks must go via the back of the chain, the cleats need to be inserted on the outside the house, and the openings of the cleats need to be dealing with the opposite route of rotation.
4. When the sprocket is seriously worn, the new sprocket and new chain need to be replaced at the exact same time to make certain good meshing. New chains or sprockets cannot be repSpecialty Chains: A Unique Decision for Your Unique Venture Often a normal roller chain basically just isn’t appropriate for your undertaking – you’re both in a challenging environment or have heavy-obligation specifications or demanding purposes. Even though we also offer you machining choices for chains and attachments, these “regular” specialty chains are our most popular. Do you need nails to the best of a chain or binding chain? no problem! Our specialist chain stores are usually at your services. From spires to facet bows, every of our specialty chains is built to exacting ANSI expectations, so you can be self-assured your device will operate as predicted without having unforeseen failures or chain bends.
laced individually. Failure to do so will consequence in very poor meshing and accelerated put on of the new chain or sprocket. Soon after the sprocket tooth surface area is worn to a specific extent, it need to be fixed in time. Prolong utilization time.
five. The old lifting chain can not be mixed with a element of the new chain, normally it will very easily cause transmission vibration and harm the chain.
six. Remember to include lubricating oil in time in the course of perform. Lubricant must enter the gap among the rollers and the inner sleeve to enhance doing work problems and minimize put on.

The function of chain parts
Chain plate
The chain plate is the part that bears the tension on the chain and bears repeated loads, sometimes accompanied by shocks. As a result, the chainplate need to not only have static strong tensile toughness but also have the ability to withstand masses and impacts. In addition, the chainplates must fulfill environmental resistance requirements (e.g. corrosion, use, and many others.).
pin
The pin bears the shearing power and benDue to the vast range of apps of chain drives, clarification of their general
Servicing and mend techniques are practical upkeep and fix
The better you do it, the much less faulty the chain generate will be. practice displays that,In use, if you can adhere to a few comparatively simple servicing rules Then you can conserve charges, lengthen your daily life and get the most out of The working capacity of chain generate:
1. Every single sprocket of the transmission must keep good coplanarity, and the chain channel need to be kept unobstructed
2. The sag of the loose edge of the chain should be stored acceptable. For pan and tilt drives with adjustable centre distance, the chain sag ought to be managed at center length.
About 1%~2%, for vertical transmission or vibration load, reverse transmission, and dynamic braking, the chain sag must be far more minimal. frequently Checking and modifying chain slack is an essential component of chain push upkeep.
three. Often sustain great lubrication, which is an crucial component of servicing function. No subject which lubrication strategy is utilised, the most important issue is In time, the grease is evenly dispersed into the hole of the hinge. Try not to use large sticks if not needed Oil or grease, as they are likely to clog the passage (gap) to the friction surface of the hinge with dust right after a time period of use.
The roller chain ought to be cleaned and decontaminated often, and the lubrication impact ought to be checked frequently. If essential, the pin and sleeve should be disassembled for inspection, these kinds of as friction.
When the surface is brown or dim brown, it is normally induced by insufficient oil source and bad lubrication.
4. The sprocket must be stored in excellent working situation.
five. Usually examine the operating floor of the sprocket teeth. If it is identified that the dress in is too rapidly, the sprocket need to be altered or changed in time.
ding pressure transmitted by the chainplate, and in the method of partaking with the sprocket, the pin and the sleeve jointly represent the bearing portion. Consequently, the pin needs high tensile power, shear power, bending resistance, and has the characteristics of impact resistance and dress in resistance.
sleeve
The sleeves are subjected to shear and bending stresses from the chainplates and rollers, and the sleeves are also subjected to shock hundreds when the chain is engaged with the sprockets.
Also, when the chain is tensioned, the interior area will sort a load-bearing part with the pin. The outer floor will also type a load-bearing portion with the internal area of the roller as it rotates on the observe or engages the sprocket. As a result, it need to have high specific compressive strength, shear energy, and affect and wear resistance.
roller
When the chain meshes with the sprocket, the rollers are impacted by the sprocket tooth. Soon after weaving, the stage of make contact with and drive amongst the roller and the sprocket changes. At this time, the roller is among the sprocket teeth and the sleeve and moves on the tooth surface area below the motion of force.
Furthermore, the internal area of the roller and the outer surface area of the sleeve jointly form the bearing portion when the roller rotates on the guidebook rail. For that reason, it have to have use resistance, impact resistance, fatigue resistance, and a large-force ratio coefficient.
Cotter pin, elastic locking plate, locking pin
These elements prevent the outer chain plate from shifting and slipping off following the pin is moved axially. When the chain is operating, these components could collide with other areas on the gear and drop off, so the set up course and bending angle of these parts are essential.
