Vertical Single Axis Solar Slew Drive Worm Gear Enclosed House For PV Trackers
Vertical Single Axis Solar Slew Drive Worm Gear Enclosed House For PV Trackers
Solar Slew Drive Description
The enclosed house type horizontal slewing drive reducer is assembled by a house type base, a slewing gear, a worm and other supporting parts. It can use an electric motor, stepper motor or a hydraulic motor as a power input source to drive the reducer to rotate clockwise or counterclockwise. Because the double enveloping worm ang gear are used as the main design components, the device has a strong overturning moment and axial force in slow moving applications. Compared with the reducer with the same parameters, the device has a small size and is easy to install and maintain.
