1. The reducer can be divided into two types according to the purpose: general reducer and special reducer. The design, manufacture and use characteristics of the two are different. In the 1970s and 1980s, the world's reducer technology has developed greatly and is closely integrated with the development of the new technological revolution. Its main types: gear reducer; worm reducer; gear-worm reducer; planetary gear reducer. 2, the general reducer has helical gear reducer (including parallel shaft helical gear reducer, worm gear reducer, bevel gear reducer, etc.), planetary gear reducer, cycloidal pin reducer, worm gear reducer, planet Friction mechanical stepless speed changer and so on. 1) Cylindrical gear reducer Single, secondary, secondary and above. Arrangement: unfolded, split, coaxial. 2) Bevel gear reducer Used when the input shaft and output shaft position intersect. 3) worm reducer It is mainly used in the case of transmission ratio i>10, and the structure is compact when the transmission is large. The disadvantage is that it is inefficient. The Archimedes worm reducer is widely used. 4) Gear-worm reducer If the gear transmission is at a high speed level, the structure is compact; if the worm drive is at a high speed level, the efficiency is high. 5) Planetary gear reducer The transmission efficiency is high, the transmission ratio range is wide, the transmission power is 12W~50000KW, and the volume and weight are small. 3. Types of common reducers 1) The main feature of the worm gear reducer is that it has a reverse self-locking function and can have a large reduction ratio. The input shaft and the output shaft are not on the same axis, nor on the same plane. However, the volume is generally large, the transmission efficiency is not high, and the accuracy is not high. 2) Harmonic transmission of harmonic reducer is the use of flexible deformation controllable elastic deformation to transmit motion and power, small volume, high precision, but the disadvantage is that flexible wheel life is limited, not impact resistant, rigid and metal parts Relatively poor. The input speed cannot be too high. 3) Planetary reducer has the advantages of compact structure, small return clearance, high precision, long service life and large rated output torque. But the price is slightly more expensive. Reducer: In short, after the power of a general machine is designed and manufactured, its rated power does not change. In this case, the higher the speed, the smaller the torque (or torque); the smaller the speed, the greater the torque.
