A slewing reducer is an important transmission component in the fields of construction machinery and industrial control, capable of achieving low-speed, high-torque, and high-load output. It mainly consists of a base, worm, central shaft, as well as a motor, bearings, seals, flanges, and other components. The principle of operation involves utilizing the large transmission reduction ratio of the worm gear and worm to reduce the speed of the motor and amplify the torque. The reducer serves to match the rotational speed and transmit torque between the prime mover and the working machine or actuator, making it a relatively precise mechanism. Meanwhile, the output of the reducer adopts structures such as slewing bearings, which can simultaneously withstand large axial forces, radial forces, and overturning moments.

Photovoltaic power generation is an important application area for slewing reducers. The slewing reducer is a core component of the tracking system used in photovoltaic power generation. Driven by a motor, it rotates the driven photovoltaic modules at a certain speed in the horizontal or elevation direction. Based on the sun's position throughout the day, it precisely adjusts the angle and elevation of the photovoltaic modules to maintain the optimal receiving angle for the solar panels, significantly improving solar power generation efficiency. Additionally, in extreme weather conditions such as strong winds, the slewing reducer can utilize its unique self-locking characteristics to keep the photovoltaic modules stable at a wind-sheltered angle, ensuring the safe and smooth operation of the photovoltaic power station.
