Planetary reducers

A planetary reducer is a high-precision transmission device that uses coaxial meshing of a sun gear, planetary gears, and an internal ring gear. Its core function is to achieve efficient connection between a servo motor and the load, driving equipment by reducing speed and increasing output torque, while effectively reducing the effects of load inertia.

Planetary reducers feature a highly integrated structure. Their one-piece gearbox design and multi-planetary gear load-sharing characteristics enable them to achieve high torque density and load distribution capabilities within a compact size. Key features include high transmission efficiency (over 97% in a single stage), low backlash accuracy (within 3 arc minutes), high input speed (typically 5000-8000 RPM), and high rigidity. These precision planetary reducers are widely used in industrial robots, CNC machine tools, automated production lines, aerospace, and medical equipment, among other fields. Their high reliability and modular design can meet the precision transmission requirements of various complex operating conditions.
