Dual Axis Slew Drive with Worm And Gear Structure For Solar
Tracking System
Worm And Gear Slew Drive Description
Slewing drives consist of slewing bearing, worm shaft, housing,
bearing, motor and so on. Motor drive the worm shaft, the outer
ring of slewing bearing will rotate, the outer ring output the
torque through flange while the inner ring of slewing bearing is
fixed in housing.

Function
Slewing drive is able to sustain more axial load, radial load and
tilting moment. Turntable or frame rotates at azimuth and elevation
driven by slewing drive.
Application
For Solar: It is designed in solar tracking system and improves
power generation efficiency.
For industrial usage: Mainly used to drive two relative rotating
objects in 360°.
Advantages
1. Designed with hourglass worm shaft which provides more tooth
contact and higher torque
2. Service life is increased by gear and raceway harden
3. Product performance is tested and ensured product quality.
There are many applications in which the slewing drive can be
utilized, primarily because it is perfect for applications that
require both load-holding power and rotational torque strength.
