Self Locking Worm Gear Small Slewing Drives, 7 Inches For Solar
Energy Systems
Worm Gear Small Slewing Drives Description
As a clean and pollution-free energy source, solar energy has a
very broad development prospect and has become a green energy
source that countries are competing to develop. However, due to the
problems of low density, intermittency, and constant changes in the
direction and intensity of sunlight over time, the traditional
fixed-installed solar photovoltaic system, that is, the panels are
fixed at a certain angle, will not change with the position of the
sun. , which seriously affects the photoelectric conversion
efficiency. Assuming that there is a 25-degree deviation between
the photovoltaic system and the sun's ray angle, the output
efficiency of the photovoltaic array will drop by about 10% due to
the reduction of vertically incident radiant energy.
Throughout the year, from day to night, the rise and fall of the
sun, the angle of the sun's rays, change all the time. Therefore,
using a rotary drive device to realize that the photovoltaic system
changes the angle of the solar panel with the light angle can
greatly improve the photovoltaic conversion rate.

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. Grease had been filled 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
8. High tilting torque, suitable for horizontal installation
