Small Size VE9" Solar Slew Drive For Horizontal Single Axis Tracking System
Small Size Heavy Duty Slew Drive For Horizontal Single Axis Solar Tracking System
Heavy Duty Slew Drive Description
The HT Slewing Drive is a gearbox designed to handle radial or axial loads with high rotational torque. In addition, the slewing ring bearing at the heart of the drive enables it to withstand high cantilever or moment loads. A descendant of the "worm" lead screw, rotary drives are found in construction machinery, manufacturing, military equipment, and many other applications where strength and precision are required.

Features
From material to finished product, our worm drives are designed, tested and guaranteed for tracking accuracy of efficiency according to customers’special requirements.
Slewing drive can realize unlimited circumferential rotation and speed reduction, and can withstand larger axial force, radial force and overturning force. It enjoys advantages of high accuracy, compact structure and large carrying capacity.
Applications
The physics of slewing drives make them a versatile solution for many applications. In operation, the axial motion of the slewing drive, or motion about its axis, interacts to generate radial torque. This action occurs by meshing the grooves of the horizontal worm with the teeth of the vertical gear. When turning, the axial movement of the worm gear transfers the amplified torque force to the radial gears. The number of threads on the worm and the number of gears interacting will determine the speed ratio of the unit. Slewing drives are best suited for applications where high torque can produce precise positioning and rotational accuracy. This design keeps the unit running smoothly and powerfully with minimal clearance.
