The structure of reducer is mainly composed of gearbox, transmission motor, transmission shaft and output shaft
1. Gearbox: gear set, transmission shaft, box and washer.
2. Gear series: there are single-stage, double-stage and three-stage reducers, but some of them with large reduction ratio can reach four stages, and the larger the series, the lower the efficiency of reduction drive.
3. Drive motor: DC brush motor, DC brushless motor, stepping motor, hollow cup motor, motor, permanent magnet motor can be used.
4. Transmission shaft: sintered bearing, rolling bearing.
5. Output shaft: metal output shaft, plastic output shaft.
