SDE9 Dual axis slew drive with 24V dc motor for solar tracker system and for solar panels
SDE9 Dual axis slew drive with 24V dc motor for solar tracker system and for solar panels
Introduction
Slewing drives are perfect for situations requiring both load-holding and rotational torque from the same gearbox.Ttypical applications include solar trackers, wind turbines, satellite and radar dishes, truck cranes, man lifts, utility equipment, hydraulic equipment attachments, oil tool equipment, tire handlers, digger derricks, and automotive lifts.
The performance ranges from 6kNm to 220kNm of holding torque, 200Nm to 63kNm of output torque, 500Nm to 271kNm of overturning moment load capacity, and gearbox reduction ratios of 30:1 up to 156,600:1. The mounting can be done horizontally, vertically, or across a combination of multiple axes.
Vertical installation
It is advised to mount the slewing drives referring to attached drawing upside in solar applications for better protection.
For other applications, the mounting directions shall be based on the evaluation of the protection level and it shall be better for better protection.
Horizontal installation
It is advised to mount the slewing drives upside down on the azimuth axis in solar applications for better protection and add protection for the elevation axis.
For other applications, the mounting directions shall be based on the evaluation of the protection level and it shall be better for better protection.

Application
Slew drives are widely used in solar industry, truck cranes, man lifts, utility equipment, hydraulic attachments, oil tool equipment, marine cranes, tire handlers, digger derricks and automotive lifts.
Glossary
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.
