What are the types and functions of the common reducers?

What are the types and functions of the common reducers?. According to the needs of the reducer, to choose different types of reducer. According to the different characteristics of the reducer, the types of different reducers can be distributed. The common reducer includes worm gear reducer, planetary reducer, harmonic reducer.
First, the types of common reducer
(1) the harmonic drive of the harmonic reducer is to transfer the motion and power by the flexible deformation controlled by the flexible component. It has small volume and high precision, but the disadvantage is that the life of the flexible wheel is limited and the impact is not good, and the rigidity is relatively poor compared with the metal parts. The input speed can not be too high.
(two) planetary reducer has the advantages of compact structure, small return clearance, high accuracy, long service life, rated output torque can be done a lot. But the price is slightly expensive.
(three) the main feature of the worm gear reducer is the reverse self-locking function, which can have a large reduction ratio. The input shaft and output shaft are not on the same axis, nor on the same plane. But the general volume is large, the transmission efficiency is not high, the accuracy is not high.
Two, the role of reducer
(1) the 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 the general motors have an inertia value.
(two) reduce the speed and increase the output torque, torque output ratio by motor output multiplication and deceleration ratio, but be careful not to exceed the rated torque of the reducer.
Three. Types of reducers
The general reducer has helical gear reducer, including parallel shaft helical gear reducer, worm gear reducer, bevel gear reducer, etc., planetary gear reducer, cycloid pin gear reducer, worm gear reducer, planetary friction type mechanical stepless speed variator, etc..
Reducer is generally used in transmission equipment, low speed high torque motor. The gear gear output shaft power internal combustion engine or other high speed running through the reducer input shaft less number of teeth on the reducer to achieve the purpose of general reducer will have several pairs of the same principle to achieve the ideal effect of gear reducer. The size of the number of teeth of the gear ratio, the transmission ratio is.
