When should a motor be equipped with a reducer?

Reducer, also called reducer, is a relatively precise mechanical device. It is a gear set between the motor and the machine that reduces the speed of power transmission.

So under what circumstances does the motor need to be equipped with a reducer? Generally there are two situations:

1. When the speed requirement of the servo motor is very low. If the speed needs to reach 10rpm, full torque output is required, and the servo motor itself cannot do the job for a long time, a reducer is required.

2. When the frequency converter requires a low speed and a relatively large torque, it can also be achieved through a reducer.

The reduction motor is a relatively precise machine with many types, different models and different uses. According to the transmission type, it can be divided into gear reduction motor, worm gear reduction motor and planetary gear reduction motor.

1. The gear reduction motor saves space, is reliable and durable, has high overload capacity, the power can reach more than 95KW, low energy consumption, superior performance, and the reducer efficiency is as high as 95% or more; it has low noise and high energy saving. It uses high-quality segment steel materials and has strong rigidity. Cast iron box body, gear surface undergoes high-frequency heat treatment;

2. The advantages of planetary reducer are relatively compact structure, small return clearance, high precision, long service life, and the rated output torque can be very large. 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 the output shaft are not on the same axis or on the same plane. However, they are generally large in size, low in transmission efficiency, and low in precision.

Reducers have two main uses. That is, multiplying the torque (input) generated by the power source; reducing the input speed so that the output speed reaches a precise value.

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