Low Noise SDE Slew Drive Gearbox With High Holding Torque For Dual
Axis Solar Tracking System
Low Noise SDE Slew Drive Description
The dual axis solar tracker includes a moving platform, a fixed
platform, a serial chain, a parallel chain and a driving device
such as dual axis solar tracker slewing drive. The moving platform
is supported by the serial chain and driven by the parallel chain,
forming a parallel tracking mechanism. slew drive for dual axis
solar tracker is configured to drive the parallel chain to motion
so as to drive the moving platform to rotate around vertical and
horizontal axes. The dual axis solar tracker slewing drive of the
present disclosure has a larger workspace, a better tracking
performance and advantages of high rigidity, low energy
consumption, small driving torque and low inertia, etc.

Glossary of Key Parameters
Tilting Moment Torque: Torque is the load multiplied by distance between the position of
load and the center of slewing bearing. If the qorque generated by
load and distance is greater than the rated tilting moment torque,
slewing drive will be overturned.
Radial load: Load vertical to the axis of slewing bearing
Axial load: Load parallel to the axis of slewing bearing
Holding torque:It is the reverse torque.When the drive is rotating reversely, and
parts are not damaged,The maximum torque achieved is called holding
torque.
Self-locking: Only when loaded, the slewing drive is not able to reverse rotate
and thus called self-locking.
