AI Technical Summary

Technical Problem

Existing reducers have poor reliability under complex outdoor working conditions. The rotation range between the torque output and torque input components is limited, making them unable to adapt to more working conditions. Furthermore, their torque transmission efficiency is low, leading to unstable operation of the photovoltaic tracking system and potentially causing power generation losses.

Method used

Design a universal assembly for a rotary reducer, with two first grooves and key pins between the torque output component and the torque input component, allowing rotation within a 360° range. The rotation range is increased through the sliding fit of the ball joint and the key pin, and the torque transmission stability is improved through planar or arc-shaped surface contact.

Benefits of technology

It realizes universal drive that can rotate in any direction, improves the reliability of the reducer and the torque transmission efficiency, ensures the photovoltaic panel remains stable under complex working conditions, reduces transmission deviation and jamming, and improves the operational stability and power generation efficiency of the photovoltaic tracking system.
