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.
