9 Inch Vertical Worm Gear Slew Drive For High Torque Solar Tracking System
Worm Gear Slew Drive Description
Slewing ring bearing a compact solution with high transmission, consisting of a slewing ring with external gear, combined with an adjoining geared worm shaft. By the self-locking gearset, no break is necessary on the driving engine. Also available with directly mounted planetary geared motors.Worm drive—higher wear-resistance of worm gear drive, which can load strong output torque and tilting moment torque with the well performance of stability and reliability. The worm drive is also available for higher tracking precise field.
