How many kinds of common reducers are there


The reducer plays a vital role in aluminum shredder operating.The reducer is a device that converts small power motor small power into large power.
General reducers include helical gear reducers (including parallel helical gear reducers, worm gear reducers, bevel gear reducers, etc.), planetary gear reducers, cycloidal pinwheel reducers, worm gear reducers, planetary friction mechanical stepless speed reducers and so on.
1) The main characteristic of worm gear reducer is that it has reverse self-locking function, and can have a large deceleration ratio. The input and output axes are not on the same axis, nor on the same plane. But generally, the volume is large, the transmission efficiency is not high, and the accuracy is not high.
2) Harmonic drive of harmonic reducer uses flexible components to control elastic deformation to transmit motion and power. It is small in size and high in accuracy, but its shortcoming is that flexible wheels have limited life and can not withstand impact, and its rigidity is worse than that of metal parts. The input speed should not be too high.
3) Planetary reducer has the advantages of compact structure, small return clearance, high accuracy, long service life, and large rated output torque. But it's a little expensive.
