Worm reducer Worm reducer plays a role in matching the speed and torque transmission between the prime mover and the working machine or actuator. It is widely used in modern machinery.
Reducer by application Can be divided into two categories of general reducer and special reducer, the design, manufacturing and use characteristics of the two are different. Its main types: gear reducer; worm reducer; gear-worm reducer; planetary gear reducer.
General reducer There are helical gear reducers (including parallel shaft helical gear reducers, worm gear reducers, bevel gear reducers, etc.), planetary gear reducers, cycloidal pin gear reducers, worm gear reducers, planetary friction mechanical stepless speed change Machine and so on. 1) Cylindrical gear reducer Single-stage, two-stage, two-stage or higher. Layout form: unfolding type, split type, coaxial type. 2) Bevel gear reducer It is used when the position of the input shaft and the output shaft intersect. 3) Worm reducer It is mainly used in occasions with transmission ratio i> 10, and the structure is compact when the transmission is relatively large. The disadvantage is that it is inefficient. Widely used Archimedes worm reducer. 4) Gear-worm reducer If the gear drive is in the high-speed stage, the structure is compact; if the worm drive is in the high-speed stage, the efficiency is higher. 5) Planetary gear reducer High transmission efficiency, wide transmission ratio range, transmission power 12W ~ 50,00000KW, small size and weight.
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 and are not on the same plane. But generally the volume is large, the transmission efficiency is not high, and the accuracy is not high. 2) The harmonic transmission of the harmonic reducer uses the controllable elastic deformation of the flexible element to transfer motion and power. The volume is small and the accuracy is high, but the disadvantages are the limited life of the flexible wheel, the impact resistance, the rigidity and the metal parts Comparatively poor. The input speed cannot be too high. 3) The advantages of planetary reducer are compact structure, small backlash, high accuracy, 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. At this time, the greater the speed, the smaller the torque (or torque); the smaller the speed, the greater the torque.
