Vertical Solar Tracker Slew Drive With Envelope Worm For Solar Renewable Energy
Solar Tracker Slew Drive Description
Slewing ring, also known as slewing bearings or turntable bearing, is a large bearing which is able to sustain the more axial load, radial load and tilting moment. It is the essential machinery transmission parts. It has the inner and outer ring, rolling and other components.
One can consider the slewing drive as a gearbox because the core motion components are the slewing bearing and worm shaft. It also consists of auxiliary components such as seals, housing, and motor. As a power source, slew drive motor is usually DC planetary gear motor, DC stepper motor, AC gear motor etc. AC hydraulic motor is mainly used in the construction machinery as a power drive system. As the core component is slewing ring drive, slewing drive can readily withstand the axial and radial forces.

Slewing Drive Working Principle
The worm is driven by the motor, which drives the outer ring of the slewing ring to rotate; the outer ring output the torque through the flange and the inner ring of the slewing ring is fixed in the housing.
Slewing drive has reverse self-locking because of worm gear drive with reverse self-locking characteristics. This feature greatly enhances the stability of the host operating and safety factor. Compared to the traditional swing products, slewing drive gearbox is easy to install, easy to maintain, and saves considerable installation space.
