introduction：Reducer principle and type Principle and type of reducer The reducer refers to an independent closed transmission device between the original motor and the working machine，Used to reduce the speed and increase the torque accordingly。In addition，On some occasions，There are also devices used as speed increases，And called speeder。 There are many kinds of retarders，Here we are talking only about being driven by gears、Worm drive and the reducer composed of them。If it is divided according to transmission and structural characteristics，There are the following five kinds of reducers： 1、Gear reducer The main cylindrical gear reducer、Bevel gear Retarder and cone-Cylindrical gear reducer。 2、Worm reducer main
