High Holding Torque Dual Axis Slew Drive For Solar Tracking System
Dual Axis Slew Drive Description
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 selflocking.

Dual Axis Slew Drive Products
Dual axis slew drives are perfect solutions in the dual axis solar tracking applications. Dual axis slew drive have three types solutions with slew drives:
In general, for easy bracket structure, the sde slew drive would be the perfect solution, but the other two are also very popular.
Two horizontal tracking slew drives
One horizontal tracking slew drive and one vertical tracking slew drive
Dual Axis Slew Drive Application
The slewing drive device can be used in any occasions where full-circle rotation is required at the same time as the speed change is required. When it is necessary to realize the power transmission of larger torque, the movement transmission of higher precision, or the choice of the mechanism that requires a compact body structure and high integrity, the slewing drive Devices are the solution.
The more common applications are usually the full-circle rotary structure of engineering and construction machinery, as well as solar energy, wind energy and various long-term automatic tracking machinery. It is easy to carry out digital control, so it has many applications in the field of industrial robots.
