A planetary reducer is a precision mechanical device that uses the principle of planetary gear transmission to achieve speed reduction and torque increase. Its core structure includes a sun gear, multiple planet gears, an internal ring gear, and a planet carrier. Through multi-stage planetary gear meshing, it efficiently converts the high-speed rotation of the motor into low-speed, high-torque output. The housing is made of high-strength aluminum alloy or cast steel, featuring a compact structure, high transmission efficiency (>97%), and minimal backlash (≤3 arc minutes). It significantly enhances the transmission accuracy and load capacity of equipment and is widely used in high-precision, high-torque transmission scenarios.
