Various types of reducer characteristics

The reducer is a relatively precise machine that matches the rotational speed and transmits torque between the prime mover and the working machine or actuator. Its purpose is to reduce the speed and increase the torque. There are many types and models, and different types have different uses. There are many types of reducers, which can be divided into gear reducers, worm reducers and planetary gear reducers according to the type of transmission; according to the number of transmission stages, they can be divided into single-stage and multi-stage reducers; according to the shape of the gear can be divided into cylindrical Gear reducers, bevel gear reducers and bevel-cylindrical gear reducers. According to the transmission arrangement, it can be divided into expansion reducer, split reducer and coaxial reducer. The main feature of the worm gear reducer is that it has a reverse self-locking function, which can have a large reduction ratio. The input shaft and output shaft are not on the same axis or plane. However, it is generally larger in size and has lower transmission efficiency and accuracy. The harmonic drive of the reducer uses the controllable elastic deformation of the flexible element to transmit motion and power, with small size and high precision. However, the disadvantage is that the flexible wheel has a limited life, is not resistant to impact, and has poor rigidity compared with metal parts. The input speed cannot be too high. The planetary reducer has the advantages of compact structure, small return clearance, high precision, long life and large rated output torque. But the price is slightly more expensive. The gear reducer has the characteristics of small size and large transmission torque. The gear reducer is designed and manufactured on the basis of the modular combination system, with various motor combinations, installation forms and structural schemes. The transmission ratio is finely graded, which can meet different working conditions and realize mechatronics. The gear reducer has high transmission efficiency, low energy consumption and superior performance. Cycloidal pin gear reducer is a transmission model based on the principle of cycloid pin gear meshing planetary transmission. It is an ideal transmission with many advantages, is widely used, and can operate in both directions.
