VE5 40 To 1 Gearbox For Solar Panel Horizontal Single Axis Trackers
Enveloping Worm Gear Description
The slewing drive is a new type of rotary and transmission product. It is usually called slewing drive or slewing bearing, which is usually composed of double enveloping worm, gear, housing, motor and other components. Since the core components are the double enveloping worm, it can mesh with the gear more closely and to achieve multi tooth contact, thus improve the accuracy and the holding moment torque. They can simultaneously withstand axial forces, radial forces, and overturning moments. Compared with traditional rotary products, the new slewing drive features easy installation, easy maintenance and a greater degree of installation space.

Applications
There are 10 different sizes of VE type slewing drives, starting
from 3' size to 25" inch, among them are 5", 7", 9" 12", 14", 17" ,
19" and 21". They are both widely used in solar tracking systems
(PV, CPV, HCPV and heliostat) and regular vehicles, such as man
lifts, truck cranes, as well as modular vehicles.
