Dual Axis Solar Tracker Slew Drive With Planetary Geared Motor For Solar Tracking System
Introduction
SDE7 7 inch dual axis slew drive are perfect for situations which need track towards the sun all the time from sunrise to sunset. It can increase the energy production capacity. Typical applications include dual axis solar trackers, it can also applied in satellite and radar dishes, machines which need moving 360 degrees at both directions.
Features
1. Enveloping worm drive inside
2. Multi tooth contact to ensure high load
3. Self-locking function
4. Can be matched with different kind of motors

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.
Application
The slewing drives can be used for a wide range of applications. The areas of deployment range from excavators and cranes, opencast mining and wind turbines, to antenna. Other fields of application include engineering and solar tracking system.
