What are the types and functions of common reducers?

There are various types of reducers to meet different needs. Below, we will introduce the types and functions of common reducers? I hope it can be helpful to you.

1、 Common types of reducers

（1） The harmonic transmission of harmonic reducers utilizes the controllable elastic deformation of flexible components to transmit motion and power. It is small in size and has high accuracy, but its disadvantages are limited service life of flexible wheels, lack of impact resistance, and poor rigidity compared to metal parts. The input speed cannot be too high.

（2） The advantages of planetary reducers are their compact structure, small return clearance, high accuracy, long service life, and large rated output torque. But the price is slightly expensive.

（3） The main feature of a worm gear reducer is its reverse self-locking function, which can have a large reduction ratio. The input and output shafts are not on the same axis or plane. But generally, the volume is relatively large, the transmission efficiency is not high, and the accuracy is not high.

2、 The function of the gearbox

（1） The speed simultaneously reduces the inertia of the load, which is reduced by the square of the deceleration ratio. Everyone can take a look. Generally, motors have an inertia value.

（2） Reduce the speed while increasing the output torque. The torque output ratio is calculated by multiplying the motor output by the reduction ratio, but be careful not to exceed the rated torque of the reducer.

3、 Types of reducers

General reducers include helical gear reducers, including parallel axis helical gear reducers, worm gear reducers, bevel gear reducers, etc., planetary gear reducers, cycloidal pinwheel reducers, worm gear worm reducers, planetary friction mechanical continuously variable transmissions, etc.

Reducers are generally used for low speed and high torque transmission equipment, where the power of electric motors, internal combustion engines, or other high-speed operation is reduced by meshing the small number of teeth on the input shaft of the reducer with the large gear on the output shaft. Ordinary reducers also have several pairs of gears with the same principle to achieve ideal deceleration effect, and the ratio of the number of teeth of the large and small gears is the transmission ratio.
