VE7 Single Axis Worm Gear Slewing Bearings With Nema23 For Solar
Tracking Systems
Enclosed VE Type Slew Drive Description
The rotary reducer is an independent closed transmission device
between the prime mover and the working machine, which is used to
reduce the speed and increase the torque to meet the work needs. At
present, the main parameters of the reducer, such as center
distance, transmission ratio, module, tooth width coefficient,
etc., have been standardized. The rotary reducer is a worm drive
gear to achieve the effect of deceleration. Driven by the motor,
the worm drives the outer ring of the slewing bearing to rotate,
the outer ring outputs torque through the flange, and the inner
ring of the slewing bearing is fixed in the base. Rotary reducers
are widely used in the field of solar photovoltaic power
generation.

Applications
In the continuous development of solar light energy, the production
technology of photovoltaic systems has been continuously improved
and has been widely used in various fields. A photovoltaic system
is a device that directly converts light energy into electrical
energy through the photoelectric effect or photochemical effect.
The photovoltaic system is the core part of the solar power
generation system and the most valuable part of the solar power
generation system. Photovoltaic systems can not only convert solar
energy into electrical energy, but also store the electrical energy
in batteries, or use it to drive loads. In order to improve the
power generation efficiency of the photovoltaic system and reduce
its power generation cost, the angle of the solar panel is
generally adjusted by the rotary drive device, so that the solar
panel can effectively track the sun, thereby effectively improving
the utilization rate of the solar panel and improving the power
generation efficiency.
