According to the needs of the reducer, different types of reducer should be selected. According to the different characteristics of the reducer, different types of reducer can be distributed and divided. Common reducers include worm gear reducers; planetary reducers; harmonic reducers.

1. Common types of reducers

(1) The harmonic transmission of the harmonic reducer uses the controllable elastic deformation of the flexible element to transmit the motion and power. relatively poor. The input speed should not be too high.

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

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

2. The role of the reducer

(1) The speed reduces the inertia of the load at the same time, and the reduction of the inertia is the square of the reduction ratio. You can look at the general motor has an inertia value.

(2) Reduce the speed and increase the output torque at the same time. The torque output ratio is the motor output multiplied by the reduction ratio, but attention should be paid not to exceed the rated torque of the reducer.

Three, the type of reducer

General reducers include helical gear reducers, including parallel shaft helical gear reducers, worm gear reducers, bevel gear reducers, etc., planetary gear reducers, cycloidal pin wheel reducers, worm gear reducers, planetary friction machinery without Gearbox etc.

The reducer is generally used for transmission machinery with low speed and high torque. The motor, internal combustion engine or other high-speed running power is used to achieve the purpose of deceleration through the gear with a small number of teeth on the input shaft of the reducer and the large gear on the output shaft. Ordinary The reducer 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 the large and small gears is the transmission ratio.
