VE9 Worm Gear Module Solar Tracker Slew Drive For Solar Tracking
System
Worm Gear Self Lock Slew Drive Product Description
The slewing drive is a reduction transmission mechanism integrated
with a driving power source. It features with worm gear mechanism,
so it is sef locking. It also has housing outside and skeleton
sealing, so the protection degree is IP66.
The slewing drive's rotation can be in a single axis, or in
multiple axes together. It is a general-purpose reduction
transmission mechanism that integrates the functions of rotation,
deceleration, and having a simple structure and convenient
manufacture and maintenance at the same time.

Features
Slewing drive can realize unlimited circumferential rotation and
speed reduction, and can withstand larger axial force, radial force
and overturning force. It enjoys advantages of high accuracy,
compact structure and large carrying capacity. It is designed,
tested and used for a 30-year field life.
Applications
Slewing drive application are usually found in such as: wind
turbines, heavy load transporters, solar trackers, harbor cranes,
hydraulic equipment, crane steering mechanisms, automation systems,
heavy load manipulators, yaw and pitch control tables.
