The reducer is a kind of relatively precise machinery. The purpose of using it is to reduce the speed and increase the torque. It has many kinds, different models, different kinds and different uses. There are many kinds of reducers, which can be divided into:
Gear reducer, worm reducer and planetary reducer;
According to the different transmission stages, it can be divided into single-stage and multi-stage reducers;
According to the gear shape, it can be divided into cylindrical gear reducer, conical gear reducer and conical cylindrical gear reducer;
According to the arrangement of the transmission, it can be divided into the expansion type, the shunt type and the coaxial type. The following are the commonly used reducer classifications:
