Coresun Drive Equipment Changzhou Co., Ltd. Slewing drives function with standard worm technology, in which the worm on the horizontal shaft acts as the driver for the gear. The rotation of the horizontal screw turns a gear about an axis perpendicular to the screw axis. This combination reduces the speed of the driven member 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.

For slewing drive, there are nine (9) different sizes available from 3" to 25" with more than 60 models to meet both regular and precise tracking requirements in PV, CPV and solar thermal power tracking fields.

Slew Drive is a new type of slewing product, usually called slewing ring, which is usually composed of worm, slewing ring, housing, motor and other components. Since the core components are slewing bearings, they can simultaneously withstand axial forces, radial forces, and overturning moments. Compared with traditional rotary products, the new slewing drive features easy installation, easy maintenance and a greater degree of installation space.

 Slew Drive are widely used in PV,CPV,STP solar tracking systems and construction applications including truck cranes, manlifts, turntables, port machinery, modular vehicles, small wind power systems and satellite communications.
