The common effect of the reducer and frequency converter on the transmission equipment is to reduce the speed. However, the reducer is actually a power transmission mechanism, which does not generate power itself. Its role is to use different gear sizes and speed converters. , Decelerate the number of revolutions of the motor (motor) to the number of revolutions you want; and get a larger torque mechanism. In the current mechanism for transmitting power and motion, the application range of the reducer is quite wide. What is the reducer?
In the current mechanism for transmitting power and motion, the application range of the reducer is quite wide. For example, the gear reducer can be seen in almost all kinds of mechanical transmission systems. From the transportation of ships, cars, locomotives, construction heavy equipment, bicycles, the principle is similar to the reducer, used in the machinery industry. Processing equipment and automated production equipment, to common household appliances, clocks, etc. in daily life. Its applications range from large power transmission to small loads, precise angle transmission can be seen in the application of reducers, and in industrial applications Above, the reducer has the functions of deceleration and torque increase. Therefore, it is widely used in speed and torque conversion equipment. For example, the elevator we make every day uses the worm gear reducer.

The main functions of  reducer are:

(1) Reduce the speed and increase the output torque at the same time, 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.
(2) Deceleration also reduces the inertia of the load, and the reduction of inertia is the square of the reduction ratio. You can see that the general motor has an inertia value.
Reducer is a relatively precise machine, the purpose of using it is to reduce the speed and increase the torque. It has many types and different models, and different types have different uses. There are many types of reducers, according to the type of transmission can be divided into gear reducer, worm reducer and planetary gear reducer; according to the different transmission stages can be divided into single-stage and multi-stage reducer; according to the shape of the gear can be divided into cylindrical gear reduction Reducer, conical gear reducer and conical-cylindrical gear reducer; according to the layout of the transmission, it can be divided into unfolded, split-flow and coaxial reducers.
working principle
The reducer is generally used in low-speed and high-torque transmission equipment. The motor, internal combustion engine or other high-speed power is driven by the gear with a small number of teeth on the input shaft of the reducer to mesh with the large gear on the output shaft. The reducer will also have several pairs of gears with the same principle to achieve the desired reduction effect. The ratio of the number of teeth of the large and small gears is the transmission ratio.
the difference
Reducer is to reduce the speed of the motor (motor) through a mechanical transmission device, and the frequency converter is to achieve the purpose of adjusting the speed of the motor (motor) by changing the AC frequency. When the motor speed is reduced by the inverter, energy saving can be achieved.
