scraper conveyor chain

The scraper conveyor chain can be used to transport bulk materials in horizontal, inclined and vertical directions. It is often used for the transportation of raw grain, semi-finished products and finished products in grain and oil, feed processing plants. The scraper conveyor chain is suitable for the transportation of oil in the production process of grease processing plants. Transportation of raw grain from grain warehouse. 

It has the advantages of simple structure, good sealing, simple feeding and unloading device, multi-point feeding and unloading, flexible layout, and the ability to complete material transportation in multiple directions at the same time. The scraper conveyor chain of ZheJiang CHINAMFG Chain Factory adopts medium carbon quenched and tempered steel and cold heading die steel. The steel is moderately priced and easy to process. After proper heat treatment, a certain degree of toughness, plasticity and wear resistance can be obtained. Normalizing can promote the spheroidization of the structure and is suitable for surface hardening treatments such as high-frequency quenching and flame quenching. Application: After quenching and tempering, it can be used to manufacture medium load and medium speed work. The working principle of the scraper conveyor is to use the open chute as a bearing part for coal, gangue or materials, and fix the scraper on the chain (to form a scraper chain) as a traction member. When the driving part of the machine head starts, the sprocket on the driving head shaft rotates, so that the scraper chain circulates and moves the animal material along the chute until it reaches the machine head to unload. The scraper chain bypasses the sprocket and runs in a stepless closed loop to complete the transportation of materials. Other scraper conveyor chain uses and maintenance precautions have to be communicated with the supplier. The above information is for reference only.

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 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 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:

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.

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.

bush chain

Can a bush chain be used in cleanroom environments?

Yes, bush chains can be used in cleanroom environments depending on the specific requirements and design of the cleanroom. Here are some considerations:

1. Material Selection: The choice of material for the bush chain is crucial in cleanroom applications. Stainless steel or plastic chains are commonly used because they offer excellent corrosion resistance and are easy to clean. These materials also have low particle generation, which is important in maintaining cleanroom standards.

2. Lubrication: In cleanroom environments, lubrication may need to be minimized or eliminated to prevent contamination. Self-lubricating bush chains or dry lubricants can be used to reduce the need for external lubrication, minimizing the risk of particle generation.

3. Design and Construction: The design of the bush chain should minimize the potential for particle accumulation. Smooth surfaces and sealed construction can help prevent the buildup of contaminants. Additionally, the chain should be designed for easy disassembly and cleaning to facilitate regular maintenance.

4. Cleanroom Compatibility: It is essential to verify that the bush chain and any associated components, such as sprockets, meet the cleanroom requirements and standards. They should be made of materials that are compatible with the cleanroom environment and meet any necessary certifications or regulations.

When using a bush chain in a cleanroom environment, proper installation, regular cleaning, and maintenance are essential to ensure optimal performance and prevent any potential contamination. Consulting with experts or suppliers familiar with cleanroom requirements can help in selecting the appropriate bush chain and ensuring compliance with cleanroom standards.

bush chain

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.

scraper conveyor chain

The scraper conveyor chain can be used to transport bulk materials in horizontal, inclined and vertical directions. It is often used for the transportation of raw grain, semi-finished products and finished products in grain and oil, feed processing plants. The scraper conveyor chain is suitable for the transportation of oil in the production process of grease processing plants. Transportation of raw grain from grain warehouse. 

It has the advantages of simple structure, good sealing, simple feeding and unloading device, multi-point feeding and unloading, flexible layout, and the ability to complete material transportation in multiple directions at the same time. The scraper conveyor chain of ZheJiang CHINAMFG Chain Factory adopts medium carbon quenched and tempered steel and cold heading die steel. The steel is moderately priced and easy to process. After proper heat treatment, a certain degree of toughness, plasticity and wear resistance can be obtained. Normalizing can promote the spheroidization of the structure and is suitable for surface hardening treatments such as high-frequency quenching and flame quenching. Application: After quenching and tempering, it can be used to manufacture medium load and medium speed work. The working principle of the scraper conveyor is to use the open chute as a bearing part for coal, gangue or materials, and fix the scraper on the chain (to form a scraper chain) as a traction member. When the driving part of the machine head starts, the sprocket on the driving head shaft rotates, so that the scraper chain circulates and moves the animal material along the chute until it reaches the machine head to unload. The scraper chain bypasses the sprocket and runs in a stepless closed loop to complete the transportation of materials. Other scraper conveyor chain uses and maintenance precautions have to be communicated with the supplier. The above information is for reference only.

What are the benefits of using a plastic bush chain?

Plastic bush chains offer several advantages in various industrial applications. Here are some benefits of using a plastic bush chain:

1. Corrosion Resistance: Plastic bush chains are highly resistant to corrosion, making them ideal for use in humid or corrosive environments. Unlike metal chains, plastic chains do not rust or deteriorate when exposed to moisture, chemicals, or certain harsh conditions.

2. Lightweight: Plastic bush chains are significantly lighter than their metal counterparts. This lightweight nature reduces the overall weight of the system, making it easier to handle and operate. It also minimizes the load on supporting structures and reduces energy consumption.

3. Low Noise and Vibration: Plastic bush chains produce minimal noise and vibration during operation. Their smooth and quiet operation is beneficial in applications where noise reduction is required, such as in conveyor systems or assembly lines located in noise-sensitive environments.

4. Self-Lubrication: Some plastic bush chains are designed with built-in self-lubricating properties. These chains incorporate lubricating additives or solid lubricants within the plastic material, reducing the need for external lubrication. Self-lubricating plastic bush chains result in reduced maintenance requirements and prolonged chain life.

5. Chemical Resistance: Plastic bush chains exhibit excellent resistance to various chemicals, including oils, solvents, acids, and alkalis. This chemical resistance allows them to maintain their performance and structural integrity even in environments where exposure to chemicals is common.

6. Design Flexibility: Plastic bush chains offer design flexibility, allowing for customization to meet specific application requirements. They can be manufactured in various shapes, sizes, and configurations to accommodate different load capacities, speeds, and operating conditions.

7. Reduced Wear on Equipment: Plastic bush chains have lower friction coefficients compared to metal chains. This reduced friction minimizes wear on the sprockets and other mating components, extending the service life of the entire system and reducing maintenance costs.

8. Electrical Insulation: Plastic bush chains have excellent electrical insulation properties, making them suitable for applications where electrical conductivity needs to be avoided. They can be used in electrical or electronic assembly lines or environments where static electricity control is necessary.

These benefits make plastic bush chains a viable alternative to traditional metal chains in various industries, including food processing, packaging, pharmaceuticals, electronics, and many others.

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.

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.

Sea Harrier FA.2 ZA195 front (cold) vector thrust nozzle – the nozzle is rotated by a chain drive from an air motor
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.

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):

Pitch (inches) Pitch expressed
in eighths

Width (inches)
14 28 25 18
38 38 35 316
12 48 41 14
12 48 40 516
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.

How does a bush chain handle reverse rotations and backdrives?

A bush chain is designed to handle reverse rotations and backdrives effectively. Here’s how it works:

1. Non-Slip Design: Bush chains are typically constructed with interlocking link plates and precision-fitted bushings. This design ensures that the chain maintains a positive engagement with the sprockets, preventing slippage or disengagement during reverse rotations or backdrives.

2. Tooth Profile: The sprockets used with bush chains are designed with a specific tooth profile that helps in maintaining proper chain engagement even during reverse rotations. The tooth shape ensures a smooth transition of the chain from one tooth to another, minimizing the risk of skipping or jumping off the sprocket.

3. Backstop Mechanisms: In some applications where backdrives or reverse rotations are more common, additional backstop mechanisms may be employed. These mechanisms prevent the chain from moving in the undesired direction by utilizing devices such as one-way clutches or backstop sprockets.

4. Proper Chain Tension: Maintaining proper chain tension is crucial for reliable operation in reverse rotations and backdrives. Adequate tension ensures that the chain remains engaged with the sprockets and minimizes the possibility of slippage.

Overall, bush chains are designed to handle reverse rotations and backdrives without compromising their performance and reliability. However, it is important to consider the specific application requirements and consult with chain manufacturers or experts to ensure the selection of the appropriate bush chain design and components for the desired operating conditions.

What are the factors to consider when selecting a bush chain material?

When selecting a bush chain material, several factors should be considered to ensure optimal performance and longevity in specific applications. These factors include:

1. Load capacity: The material should have sufficient strength and hardness to withstand the expected load without deformation or failure. Higher load capacities typically require materials with greater tensile strength and wear resistance.

2. Wear resistance: The material should have good wear resistance to withstand the friction and abrasive forces experienced during chain operation. This is particularly important in applications where the chain may come into contact with harsh or abrasive environments.

3. Corrosion resistance: Depending on the operating environment, the chain material should exhibit resistance to corrosion caused by moisture, chemicals, or other corrosive substances. Corrosion-resistant materials, such as stainless steel or certain alloys, are commonly used in applications where exposure to corrosive elements is expected.

4. Temperature resistance: The material should be capable of withstanding the temperature range experienced in the application. High-temperature applications may require materials with heat-resistant properties to prevent deformation or loss of strength.

5. Fatigue strength: The material should have good fatigue strength to withstand repeated stress cycles without experiencing fatigue failure. This is particularly important in applications where the chain undergoes frequent start-stop or reversing movements.

6. Compatibility with lubrication: The chain material should be compatible with the lubricant used in the application. Some materials may require specific lubrication types or may be self-lubricating, while others may have limitations regarding lubrication compatibility.

7. Cost-effectiveness: Consideration should also be given to the cost-effectiveness of the material. Balancing performance requirements with cost considerations is crucial to ensure the best value for the specific application.

By carefully evaluating these factors and considering the specific requirements of the application, the most suitable material for the bush chain can be selected. Common materials used for bush chains include carbon steel, stainless steel, heat-treated alloys, and specialty polymers.

How do you troubleshoot common issues with bush chains?

Troubleshooting common issues with bush chains involves identifying the problem and taking appropriate corrective actions. Here are some common issues and their troubleshooting steps:

1. Chain Misalignment: If the bush chain is misaligned, it can cause excessive wear, noise, and premature failure. To troubleshoot this issue, check the alignment of the sprockets and adjust them as necessary. Ensure that the chain runs smoothly and evenly on the sprockets without any binding or skipping.

2. Chain Binding: If the chain becomes stuck or binds during operation, it may be due to improper lubrication, debris accumulation, or worn-out components. Start by cleaning the chain and sprockets to remove any debris or contaminants. Lubricate the chain with the recommended lubricant to reduce friction. If the issue persists, inspect the chain for signs of wear and replace any worn-out components.

3. Excessive Chain Wear: Excessive chain wear can lead to elongation, reduced performance, and increased risk of failure. To troubleshoot this issue, measure the chain’s length and compare it to the manufacturer’s specifications. If the chain has elongated beyond the acceptable limits, it needs to be replaced. Additionally, inspect the chain for signs of pin and bushing wear, plate wear, or sprocket wear. Replace any worn components as necessary.

4. Insufficient Lubrication: Inadequate lubrication can result in increased friction, wear, and premature failure of the bush chain. If the chain appears dry or there are signs of insufficient lubrication, apply the appropriate lubricant to the chain according to the manufacturer’s recommendations. Ensure that the lubricant reaches all the critical components of the chain, including the pins, bushings, and rollers.

5. Chain Breakage: Chain breakage can occur due to excessive loads, sudden impacts, or worn-out components. To troubleshoot this issue, inspect the chain for any signs of damaged or broken links. Identify the cause of the breakage, such as overload or impact, and address it accordingly. Replace the broken chain links with a new chain segment and ensure proper installation.

6. Excessive Noise and Vibration: Unusual noise and vibration during chain operation can indicate underlying issues. Inspect the chain for signs of misalignment, worn-out components, or inadequate tension. Address the specific cause by adjusting the alignment, replacing worn parts, or adjusting the tension to reduce noise and vibration.

It’s important to consult the manufacturer’s guidelines and recommendations for troubleshooting specific issues with bush chains. Regular inspection, proper lubrication, and timely maintenance can help prevent common issues and ensure the reliable and efficient operation of the bush chain.

What is a bush chain and how does it work?

A bush chain, also known as a bush roller chain or a bushing chain, is a type of roller chain commonly used in mechanical power transmission systems. It consists of a series of interconnected links, known as bushings, that are joined together by pins. The bushings are cylindrical metal sleeves with internal bearings that rotate on the pins.

The working principle of a bush chain is based on the interaction between the rotating bushings and the teeth of the sprockets. The chain is wrapped around two or more sprockets, with one sprocket being the driver and the other(s) being the driven. As the driver sprocket rotates, it pulls the chain, causing the bushings to rotate on the pins.

Each bushing has an outer surface that comes into contact with the sprocket teeth. The engagement between the sprocket teeth and the bushings’ outer surface creates the driving force, allowing power to be transmitted from the driver sprocket to the driven sprocket(s). This rotational motion transfers torque and enables the movement of various mechanical components or systems connected to the driven sprocket(s).

The bush chain design provides several advantages, including high tensile strength, flexibility, and the ability to transmit power over long distances. The bushings and pins are typically made of hardened steel to ensure durability and resistance to wear. Lubrication is essential to reduce friction and prevent premature wear of the bushings and pins.

Bush chains are widely used in various applications, such as industrial machinery, agricultural equipment, automotive systems, and conveyor systems. They are favored for their reliability, efficiency, and ease of installation. Proper maintenance, including regular lubrication and tension adjustment, is necessary to ensure the smooth operation and longevity of a bush chain.
