The reducer is an independent component composed of gear transmission, worm transmission and gear-worm transmission enclosed in a rigid housing, which is commonly used as a reduction transmission device between the actuator and the working machine. It matches the speed and transmits the torque between the prime mover and the working machine or the actuator, and is widely used in modern machinery.

The reducer is generally used for low speed and high torque transmission equipment, the motor, internal combustion engine or other high-speed operation of the power through the input shaft of the reducer with fewer teeth on the gear meshing output shaft of the large gear to achieve the purpose of deceleration, the ordinary reducer will also have several pairs of the same principle of gear to achieve the ideal reduction effect, the ratio of the number of teeth of the size of the gear, is the transmission ratio.

The reducer matches the speed and transmits the torque between the prime mover and the working machine or the actuator, and is a relatively precise machine. The purpose of using it is to reduce the speed and increase the torque. There are many kinds of it, different models, and different kinds have different uses. There are many kinds of reducer, according to the transmission type can be divided into gear reducer, worm reducer and planetary gear reducer; According to the different transmission series can be divided into single stage and multistage reducer; According to the shape of the gear can be divided into cylindrical gear reducer, bevel gear reducer and conical-cylindrical gear reducer; According to the arrangement of the transmission, it can be divided into expansion reducer, shunt reducer and coaxial reducer.

The reducer is a mechanical transmission device in many fields of the national economy, the product categories involved in the industry include all kinds of gear reducer, planetary gear reducer and worm reducer, and also include a variety of special transmission devices, such as growth devices, speed regulating devices, and various types of composite transmission devices including flexible transmission devices. Products and services involve metallurgy, nonferrous metals, coal, building materials, shipping, water conservancy, electric power, construction machinery and petrochemical industries.

The development history of China's reducer industry has been nearly 40 years, in various fields of the national economy and national defense industry, reducer products have a wide range of applications. Food light industry, electric machinery, construction machinery, metallurgical machinery, cement machinery, environmental protection machinery, electronic and electrical appliances, road construction machinery, water conservancy machinery, chemical machinery, mining machinery, conveying machinery, building materials machinery, rubber machinery, petroleum machinery and other industries have strong demand for reducer products.

The huge potential of the market has spawned fierce industry competition, in the cruel market competition, the reducer industry enterprises must speed up the elimination of backward production capacity, vigorously develop energy-saving products, make full use of the national energy-saving products benefit the people project policy opportunities, increase product renewal efforts, adjust the product structure, pay attention to the national industrial policy, in order to cope with the complex and changing economic environment, Maintain a sound momentum of development.
