VE9 Compact Worm Gearbox Slewing Drive For PV, CPV, CSP Solar Heat Tracking System
Worm Gear Slewing Drive Description
Function: Slewing drives function with standard worm technology, in which the worm on the horizontal shaft acts as the driver for the gear, in general, the shaft is driven by electric gear motor.
Gear ratio:The rotation of the horizontal worm turns a gear about an axis perpendicular to the screw axis. This combination reduces the speed of the driven unit and also multiplies its torque; increasing it proportionally as the speed decreases.The speed ratio of shafts depends upon the relation of the number of threads on the worm to the number of teeth in the worm wheel or gear.
