Common reducer types and effects introduced

According to the different characteristics of the reducer can be divided into different types of reducer. Common reducer includes: worm gear reducer; planetary reducer; harmonic reducer. Enterprises can choose according to the needs of different reducer different types.

First, the type of common reducer

1, Harmonic gearbox harmonic transmission is the use of flexible components to control the elastic deformation to transfer movement and power, the volume is not large, high precision, but the disadvantage is the limited life of the flexible wheel, impatience impact, rigidity and metal parts Compared to poor, the input speed can not be too high.

2, planetary reducer The advantages of the structure is relatively compact, small return gap, high precision, long life, rated output torque can be done very large. But the price is slightly expensive.

3, worm gear reducer is characterized by a reverse self-locking function, you can have a larger reduction ratio, the input shaft and output shaft is not on the same axis, nor in the same plane. But the general size is larger, the transmission efficiency is not high, the accuracy is not high.

Second, the role of reducer

1, speed at the same time reduce the load inertia, inertia to reduce the square of the reduction ratio. We can look at the general motor has an inertia value.

2, slow down at the same time improve the output torque, torque output ratio by motor output multiplier, but be careful not to exceed the reducer rated torque.

General gear reducer with helical gear reducer including parallel shaft helical gear reducer, worm gear reducer, bevel gear reducer, etc., planetary gear reducer, cycloid reducer, worm gear reducer, planetary friction machine Class gear and so on.

The 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 on the input shaft teeth less gear meshing the output gear on the gear to achieve the purpose of deceleration, Reducer will have several pairs of the same principle gear to achieve the desired deceleration effect, the size of the gear ratio of teeth, is the transmission ratio.
