CE And ISO VE7 Slew Drive Gearbox, Vertical Single Axis Worm Gear Slew Drive For Trackers
Description
Slewing drive has reverse self-locking feature because of worm gear drive with reverse self-locking characteristics. This feature greatly enhances the stability of the host operating and safety factor. Compared to the traditional slewing products, slewing drive gearbox is easy to install, easy to maintain, and saves considerable installation space.
Advantages
1. High backholding torque to improve the solar tracking system's safety
2. 360 degree rotating range
3. Enveloping worm drive inside
4. Multi tooth contact to ensure high load
5. Self-locking function

Glossary of Key Paramaters
Tilting Moment Torque: This torque is the gravity load multiplied by distance between the position of load and the center of slewing bearing. If the actual torque is greater than the rated tilting moment torque, slewing drive will be overturned.
Radial load: The load vertical to the axis of slewing bearing
Axial load: The 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, it is also seen as broken torque.
Self-locking: Only when there is load, the slewing drive is not able to reverse rotate and thus called self-locking.
