General reducer has a helical gear reducer (including parallel shaft helical gear reducer, worm gear reducer, bevel gear reducer, etc.), planetary gear reducer, cycloid pin wheel reducer, the worm gear and worm reducer, planetary friction type mechanical CVT machine, and so on.

Common reducer type and classification

1) the main characteristics of worm gear and worm reducer is a reverse self-locking function, can have a large reduction ratio, the input shaft and output shaft is not in the same axis, is not in the same plane. But generally the volume is larger, the transmission efficiency is not high, the precision is not high.

2) harmonic drive is harmonic reducer using the elastic deformation of flexible component controllable transfer movement and power, small size, high precision, but the disadvantage is that soft round limited life, impact resistance, not rigid compared with metal parts. Input speed cannot be too high.

3) planetary gear reducer, its advantage is more compact in structure, return small gap, high precision, long service life, rated output torque can do a lot. But the price a little expensive. Reducer: in short, the general power of machine after was designed and manufactured, its rated power will not change, at this time, the greater the speed, the smaller the torque (or torque); Speed is smaller, the greater the torque.
