VE5 Double Enveloping Worm Gear Slewing Drive for Horizontal Single-Axis Solar Tracking Systems
VE5 Double Enveloping Worm Gear Slewing Drive for Horizontal Single-Axis Solar Tracking Systems
Product Description
The VE5 slewing drive utilizes an enveloping (globoid) worm gear geometry to deliver high-ratio speed reduction with self-locking capability in a compact, enclosed assembly. Engineered for the continuous duty cycling requirements of HSAT (Horizontal Single-Axis Tracker) solar installations, this drive unit provides precise azimuth positioning while withstanding dynamic wind loads and gravitational moment loads inherent to multi-row tracker configurations.

Why Choose Double Enveloping Worm Gear Technology?
Unlike conventional cylindrical worm gears, the double enveloping design wraps the worm around the gear, increasing the contact area by up to 300%. This results in:
-
Higher torque transmission capability
-
Improved shock load resistance
-
Extended service life under continuous duty cycling
-
Better performance in harsh outdoor environments
