Concept and application of reducer

high sensitivity

- what is a reducer

reducer is a kind of power transmission mechanism. It uses the speed converter of about 190million school wheels in China in 2014 to decelerate the rotation number of the motor to the desired rotation number and obtain a larger torque

- function of the reducer

1) speed reduction and high melting point process in the production process require to increase the output torque. The torque output proportion is based on the motor output multiplied by the reduction ratio, but attention should be paid not to exceed the rated torque of the reducer

2) speed reduces the inertia of the load at the same time, and the reduction of inertia is the square of the reduction ratio. You can see that general motors have an inertia value

- types of reducers

general reducers include 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 changers, etc

- types of common reducers

1) the main feature of worm gear reducer is that it has reverse self-locking function and can have a large reduction ratio. The input shaft and output shaft are not on the same axis or plane. However, the general size is large, the transmission efficiency is not high, and the accuracy is not high

2) the harmonic drive of harmonic reducer uses the controllable elastic deformation of flexible elements to transmit motion and power. It has small volume and high precision, but its disadvantages are that the flexible wheel has limited service life, is not resistant to impact, and its rigidity is poor compared with that of metal parts. 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 a little expensive
