SE14 Gear Ratio 85 / 1 Small Backlash Worm Gear Slew Drive For Single Axis And Dual Axis Solar Trackers
Description
Structural characteristics
Slewing worm drive is consisting of worm gear, worm shaft, housing, bearing, motor and so on. Motor drive the worm shaft, the worm and envelop worm and gear are engaged to increase the torque, stable and reliable.
Performance
Slewing drive is able to sustain more axial load, radial load and tilting moment. Turntable or frame rotate at azimuth and elevation driven by slewing drive.
Application scope
Typical applications include solar trackers, wind turbines, satellite and radar dishes, truck cranes, man lifts, utility equipment, hydraulic equipment attachments, oil tool equipment, tire handlers, digger s, and automotive lifts.
