Precision planetary gear reducer is another name for planetary gear reducer in the industry. Its main transmission structure is planetary gear, sun gear and inner gear ring.
Compared with other gear reducers, precision planetary gear reducers have the characteristics of high rigidity, high precision (single stage can achieve less than 1 point), high transmission efficiency (single stage can achieve 97% - 98%), high torque/volume ratio, lifelong maintenance-free, etc. Most of them are installed on stepper motor and servo motor to reduce speed, improve torque and match inertia.
