Single Axis Slew Drive Gearbox With Electrical Motor For PV Mounting Tracking System
Slew Drive Gearbox Description
The rotary drive device is also called a rotary reducer, a gear reducer, a turntable reducer, a rotary mechanism, and a rotary drive pair. They all use the slewing bearing as the main bearing, and the auxiliary drive source uses the gear or the worm as the driving part, so as to realize the deceleration and full-circle rotation functions. The composition of the slewing drive mainly includes gears (or worms), slewing bearings, motors, housings, and bases. Slewing drives can be basically divided into single worm drive slewing drives, double worm drive slewing drives and special types of slewing drives.

Its structure adopts enveloping worm and hard tooth surface gear, which can be applied to the occasions of low speed and high torque; it is widely used in solar power generation tracking system. In order to apply it in the engineering field, many manufacturers have developed the structure of the gear and applied it in the high speed.
