Single Enveloping Worm Gear Slew Drive, Self-Locking And IP66 Grade For Solar Trackers
Description
Single enveloping worm gear slew drive is a compactly constructed unit which consists of envelop worm, gear, housing, base etc. This unit brings the advantages of a slewing drive.
Geared slewing drive is suitable for applications which demand slow rotation with a continuous or movement and capable of handling combined loads. The product is with standard dimensions for coupling an electric, hydraulic motor, servo motor etc. as well as coupling a whole system to equipment. As to its compactness and high rigidity, a worm drive system is used in various equipments such as mobile assembly platforms, satellite system, hydraulic loading cranes on haulage vehicles, small marine cranes, extendable rotating ladders, in wheel units of large marine portal transporters, it is now especially widely uesd in solar energy.
Advantages
1. Able to rotate 360 degrees
2. Able to connect a driving motor from the left or right side
3. Not necessary to adjust the gearing clearance during istallation, it is already setted before factory
4. Simple installation and low maintenance
5. Rational space utilization
6. The gear is self-locking
7. Easy and fluent method of starting and stopping
