Single Axis Enveloping Worm Slew Drive For CSP And CPV Solar Power
Stations
Slewing Drive Description
Slewing drives are comprised of worm, gear, housing, and motor
(electric or hydraulic) and it is designed for axial, radial, and
moment loading. We developed high backlash worm gear slew drives
specially for applications where high accuracy is needed.
