The reducer is a relatively precise machine. The purpose of using it is to reduce the speed and increase the torque. (Note: The torque calculation formula of the reducer)

  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 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. Gear reducer, bevel gear reducer and cone-cylindrical gear reducer; according to the arrangement of transmission, it can be divided into expansion type, split type and coaxial type reducer.The following are commonly used reducer classifications:

  1. Cycloid reducer

  2. Hardened cylindrical gear reducer

  3. Planetary gear reducer

  4. Soft tooth surface reducer

  5. Three-ring reducer

  6. Crane reducer

  7. Worm reducer

  8. Shaft-mounted hard tooth surface reducer

  9. Stepless speed changer

  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.
