Small Size High Prevention Worm Gear Slew Drive For Dual Axis Solar Tracking System
Worm Gear Slew Drive Description
The worm gear slewing drive with the worm gear mechanism is often used in the occasions where the two axis load and large transmission ratio are needed in the intermittent work. Slewing drives can be used for applications that do circular rotations. This product can be widely used in construction machinery fields such as aerial work vehicles, truck cranes, solar photovoltaic power generation, wind power generation and other new energy fields, as well as other fields of automation, machine tool manufacturing, aerospace communications, etc.

Features
1. achieve clockwise and counterclockwise rotation
2. high IP rate of 66 grade to prevent the water and dust and is very suitable for used in outside
3. three types: SE, VE and SDE series slew drives, VE series are mostly applied in solar tracking system, parabolic concertrated power, while the SE series are mostly applied in construction machinery. The SDE series are dual axis slew drives, they can help the solar system to track the sun at any time and at any direaction.
Application
Slewing drives are usually found in application such as: wind turbines, heavy load transporters, solar trackers, CSP, CPV, satellite antenna, harbor cranes, hydraulic equipment, crane steering mechanisms, automation systems, heavy load manipulators, yaw and pitch control tables.
