What are the types and functions of common reducers. According to the needs of the reducer to choose a different type of reducer. According to the different characteristics of the reducer can be divided into different types of reducer. Common reducer includes a worm gear reducer; planetary reducer; harmonic reducer.

Types of 1. common reducer

The harmonic drive of the (I) harmonic reducer uses the controllable elastic deformation of flexible elements to transmit motion and power. It is not large in size and has high precision, but the disadvantage is that the flexible wheel has limited life, is not resistant to impact, and its rigidity is compared with metal parts. Poor. The input speed cannot be too high.

The advantages of (II) planetary reducer are compact structure, small return clearance, high precision, long service life, and large rated output torque. But the price is slightly more expensive.

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

The role of 2. reducer

(I) speed also reduces the inertia of the load, which is reduced by the square of the reduction ratio. You can look at the general motor has a value of inertia.

The (II) reduces the speed and increases the output torque. The torque output ratio is based on the motor output multiplied by the reduction ratio, but it should be noted that the rated torque of the reducer cannot be exceeded.

Types of 3. reducer

General reducer has 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 mechanical stepless speed change machine and so on.

Reducer is generally used for low speed high torque transmission equipment, the motor. The internal combustion engine or other high-speed running power achieves the purpose of deceleration through the gears with a small number of teeth on the input shaft of the reducer meshing with the large gears on the output shaft. Ordinary reducers will also have several pairs of gears with the same principle to achieve the ideal deceleration effect. The ratio of the number of teeth of large and small gears is the transmission ratio.
