EG Series Slewing Drive

A slewing drive is a gearbox that handles radial or axial loads with high rotational torque. In addition, the slewing ring bearing at the heart of the drive enables it to withstand high cantilever or moment loads. A descendant of the “worm” lead screw, slewing drives are found in construction machinery, manufacturing, military equipment, and many other applications where strength and precision are required.

The physics of slewing drives make them a versatile solution for many applications. In operation, the axial motion of the slewing drive, or motion about its axis, interacts to generate radial torque. This action occurs by meshing the grooves of the horizontal screw with the teeth of the vertical gear. When turning, the axial movement of the worm gear transfers the amplified torque force to the radial gears. The number of threads on the horizontal screw and the number of interacting gears will determine the speed ratio of the unit.

To judge what kind of slewing drive you need, you have to clear out the configuration of the slew drive and the purpose of the equipment. Each unit will have differing specifications. When defining the type and capability of the slew drive, the following variables are calculated:

(1) Gear ratios
(2) Precision
(3) Weight
(4) Output
(5) Tilting moment
(6) Torque
(7) Dynamic and static axial
(8) Radial dynamic
