Slewing Drive

HZPT slewing drive is a gearbox designed to handle radial or axial loads using high rotational torque. In addition, the slewing ring bearing, at the heart of the drive, enables it to withstand high overhung or moment loads. A descendant of the “worm” screw, slewing drives are present in construction machinery, manufacturing, military equipment, and many other applications that require strength and precision.

The physics of the slew drive makes it a versatile solution for many applications. In operation, the slew drive’s axial movement, or motion around its axis, interacts to create radial torque. The action occurs by meshing the grooves of the horizontal screw with the teeth of a perpendicular gear. While turning, the worm gear’s axial movement transfers magnified torque force to the radial gear. The number of threads on the horizontal screw and the number of gears that interact will determine the speed ratio of the setup.

Slew drives work best for applications in which high torque can create precision positioning and rotational accuracy. This design results in a device that works smoothly and powerfully with minimal backlash.
