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.
