Worm Gear Dual Axis Slewing Gear Drive With Electric Motor For Solar Tracking System
Slewing Gear Drive Description
A slewing drive is a gearbox that can safely withstand radial and axial loads at the same time and transmit low-speed rotating torque. Rotation can be on a single axis or on multiple axes. The slewing drive is assembled from gears, worms, seals, housings, and motors and other auxiliary components. The enclosed type of slewing drive is usually used in solar tracking system because it needs to be used outdoors for at least 25 years field life. We can also choose a suitable electric motor or hydraulic motor according to your technical requirements.

Features
1. clockwise and counterclockwise rotation
2. IP66 protection grade to prevent the water and dust
3. SE, VE and SDE types of slewing drives meet requirement of different applications.
VE vertical single axis slewing drives are mostly applied in solar tracking system, parabolic concertrated power, while the SE horizontal single aixs slewing drives are applied in solar tracking system, construction machinery and wind turbines. The SDE dual axis slewing drives are used in PV, CSP, CPV, satellite antenna and stirling dishes.
