VE5 Small Backlash Enclosed Slewing Drive For Horizontal Single
Axis Tracking Systems
Worm Gears Slewing Drive Description
A Slew Drive, commonly referred as a worm drive, is a complete,
ready to install system that consists of gear, worm, base, top
plate and completely enclosed housing. It can be customized with
hydraulic or 12V/24V/48V electric motors, planetary gearboxes. As a
key component of the tracking system, the slewing reducer is called
the "heart" of the tracking system, and its product performance
directly affects the accuracy of the tracking system.

Applications
The worm gear and worm drive have the characteristics of reverse
self-locking, which can realize reverse self-locking, that is, only
the worm can drive the worm gear, but the worm cannot be driven by
the worm gear to move. When the lead angle of the worm is less than
the equivalent friction angle between the meshing gear teeth, the
mechanism has self-locking properties and can achieve reverse
self-locking, that is, only the worm can drive the worm wheel, but
the worm cannot be driven by the worm wheel. Such as the
self-locking worm mechanism used in its heavy machinery, its
reverse self-locking can play a role in safety protection. This
feature makes the slewing drive device widely used in lifting,
aerial work and other equipment. While improving the technological
content of the main engine, it also greatly improves the operation
stability and safety factor of the main engine. It is an important
embodiment of the safe construction application of mechanical
equipment.
