Classification of reducer
The reducer plays the role of matching the speed and transmitting torque between the prime mover and the working machine or the actuator. It is a relatively precise machine. The purpose of using it is to reduce the speed and increase the torque. It has a wide variety of different models, and different types have different uses. There are many types of reducers. According to the transmission type, they can be divided into gear reducers, worm reducers and planetary gear reducers; according to the number of transmission stages, they can be divided into single-stage and multi-stage reducers; according to the gear shape, they can be divided into cylindrical gear reducers. According to the arrangement of transmission, it can be divided into expansion reducer, split reducer and coaxial reducer.
Features of reducer
The main feature of the worm gear reducer is that it has a reverse self-locking function and can have a larger reduction ratio. The input shaft and the output shaft are not on the same axis or on the same plane. But generally the volume is large, the transmission efficiency is not high, and the accuracy is not high. The harmonic drive of the harmonic reducer uses the controllable elastic deformation of the flexible element to transmit movement and power. The volume is small and the accuracy is high. However, the disadvantage is that the flexible wheel has a limited life and is not resistant to impact. The rigidity is compared with metal parts. Difference. The input speed cannot be too high. The advantages of planetary reducer are compact structure, small return clearance, high precision, long service 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 a modular combination system. There are a lot of motor combinations, installation forms and structural schemes, and the transmission ratio is finely graded to meet different operating conditions and realize electromechanical integration. The gear reducer has high transmission efficiency, low energy consumption and superior performance. Cycloidal pin gear reducer is a transmission model that adopts the principle of cycloidal pin tooth meshing planetary transmission. It is an ideal transmission device with many advantages, a wide range of uses, and can run forwards and backwards.
