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.
