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.
