VE7 Vertical Worm Gear Slew Drive With 24VDC Electrical Gear Motors For Solar Trackers
Description
A slew worm drive system is a compactly constructed unit which consists of a slewing gear, base and worm. This unit brings the advantages of a slewing gear and a worm into one unit.
The single axis vertical slew drives are mounted vertically, it is specifically designed for flat single axis solar tracking systems that require tracking towards the sun for east to west. The precise rotation of the vertical slew drive allows the mechanism to track perfectly. This kind of vertical slewing drive is manufactured using the latest technology which incorporates hourglass mechanism.
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 Parameters
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.
