What's the difference between planetary reducer and general reducer?
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.

The size of the number of teeth of the gear ratio, the transmission ratio
is. Reducer is a power transmission mechanism, the use of gearbox speed
converter, the number of motor rotation deceleration to the desired number
of turns, and get a larger torque mechanism.
Function of reducer
1) reduce the speed and increase the output torque, torque output ratio by motor output multiplication and deceleration ratio, but should not exceed the rated torque of the reducer.
2) the inertia of the load is reduced 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.
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..
Types of common reducers
1) the main characteristics of worm gear reducer is the reverse self-locking function, which can have a larger 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.
2) harmonic drive of harmonic reducer is to use flexible components to control the elastic deformation to transfer movement and power, the volume is small, the accuracy is very high, but the disadvantage is that the flexible wheel life is limited, not impact resistance, rigid and metal parts are relatively poor. The input speed can not be too high.
3) planetary reducer has the advantages of compact structure, small return clearance, high accuracy, long service life, rated output torque can do a great deal. But the price is slightly expensive.
