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.
