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.
