SE3 Small Worm Gear Slew Drive With Electric Motor For Single Axis PV Trackers
Small Worm Gear Slew Drive Description
A slew worm drive system is a compactly constructed unit which consists of a slewing ring, base plate and worm. This unit brings the advantages of a slewing ring and a worm into one unit.
It is suitable for applications which demand slow rotation with a continuous or cyclical movement capable of handling combined loads. The product is with standard dimensions for coupling an electric or hydraulic motor as well as coupling a whole system to equipment.
Due to its compactness, high rigidity and other mentioned advantages, a worm drive system is used in varying equipment 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.
Advantages
1. Rotation 360 degrees
2. Connection of a driving motor from the left or right side
3. During installation, it is not necessary to adjust the gearing clearance; this is already set by the producer before factory
4. Simple installation and low maintenance
5. Rational space utilization
6. The gear is self-locking; therefore a brake is not necessary
7. Easy and fluent method of starting and stopping

Applications
Horizontal single-axis tracking system
Horizontal single-axis tracking system which is mainly applied in the mid and low latitude areas, connect a couple of horizontal single axis strings through a set of driving device to achieve synchronous tracking of multiple strings. Linkage array can be 6 strings, 8 strings, 10 strings and 12 strings with module mounting capacity from 20kWp to 60kWp. Annual additional electricity generation is up to 15%~23% in comparison to the fixed bracket. Applicable in different terrain, like desert, flat, fish ponds on the slope land etc.
