VE9 Single Worm Gear Slew Drive With High Torque For Linkage Solar
Tracking System
Description
Slewing drives or slewing ring bearings are rotating modules which
are compact rotational units integrated in a cast iron housing that
contains a turning ring with a gear. The gear rotates the turning
ring with great precision and allows for smooth rotation and
maximum effort.
Features
1. Reverse self-locking because of worm gear self-locking
characteristics. This feature greatly enhances the stability of the
host operating and safety factor.
2. Compared to the traditional swing products, slewing drive
gearbox is easy to install, easy to maintain, and saves
considerable installation space.

Advantages
1. Strong overturning moment based on slewing ring
2. Enveloping worm drive inside
3. Large load for using multi tooth contact
4. Static self-locking function
5. Hard stop inside
Applications
Typical slewing drive or slewing ring applications include solar
power, wind turbines, truck cranes, man lifts, utility equipment,
hydraulic equipment attachments, oil tool equipment, tire handlers,
digger s and automotive lifts.
