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.
