Planetary reducer and general reducer what is the difference

Reducer is generally used for low speed and high torque transmission equipment, the motor. Internal combustion engine or other high-speed operation of the power through the reducer input shaft gear less gear meshing output shaft gear to achieve the purpose of deceleration, the general Reducer will have several pairs of the same principle gear to achieve the desired deceleration effect, the size of the gear ratio of the number of teeth, is the transmission ratio.

Reducer is a power transmission mechanism, the use of gear speed converter, the number of revolutions of the motor deceleration to the desired number of revolutions, and get a larger torque mechanism.

   The role of reducer


1) Decrease speed and increase the output torque at the same time. The proportion of torque output should be multiplied by the output of the motor, but be careful not to exceed the rated torque of the reducer.


2) The speed reduces the inertia of the load at the same time. The reduction of inertia is the square of the speed reduction ratio. We can look at the general motor has a value of inertia.


The type of reducer


General reducer helical gear reducer (including parallel shaft helical gear reducer, worm reducer, bevel gear reducer, etc.), planetary gear reducer, cycloid reducer, worm reducer, planetary friction Mechanical continuously variable transmission and so on.


Common types of reducer


1) The main features of the worm gear reducer with reverse self-locking function, you can have a larger reduction ratio, the input shaft and the output shaft are not in the same axis, nor in the same plane. But generally larger, transmission efficiency is not high, accuracy is not high.


2) Harmonic drive harmonic drive is the use of flexible components controlled by the elastic deformation to transfer movement and power, small size, high accuracy, but the disadvantage is limited life of the flexible wheel, impatience impact, rigidity and metal parts Relatively poor. Input speed can not be too high.


3) Planetary reducer has the advantages of compact structure, small backlash, high precision, long service life and great rated output torque. But the price is slightly more expensive
