I. Overview of the reducer industry

The reducer is a separate component consisting of a gear transmission, a worm drive, and a gear-worm drive enclosed in a rigid housing, and is often used as a reduction transmission between the prime mover and the work machine. The function of matching the rotational speed and transmitting torque between the prime mover and the working machine or the actuator is widely used in modern machinery.

In the production process, the reducer mainly uses raw materials such as steel and copper and metal cutting machine tools. Most working machines have large load and low speed. It is not suitable for direct drive with prime mover. It is necessary to reduce the speed and increase the torque through the reducer. Therefore, most working machines need to be equipped with a reducer.

As one of the important basic components of industrial power transmission, the reducer is widely used in environmental protection, construction, electric power, chemical, food, logistics, plastics, rubber, mining, metallurgy, petroleum, cement, shipbuilding, water conservancy, textile, printing and dyeing. Feed, pharmaceutical and other industries.

There are many types of reducers. According to the transmission type, they can be divided into gear reducers, worm reducers and planetary gear reducers. According to the different drive stages, they can be divided into single-stage and multi-stage reducers. According to the gear shape, they can be divided into cylindrical gears. , bevel gear reducer and cone-cylindrical gear reducer; according to the transmission arrangement can be divided into expansion, split and coaxial reducer.

Third, the analysis of the competitive landscape of China''s reducer industry

The internal capital body leads the company''s production capacity to climb. According to statistics, the first echelon of domestic sales volume includes Efte, Eston, Zhongxingxing, Guangzhou Qifan, Xinshida, Xinsong Robot, Liqun Automation, Huanyan, etc. On the other hand, capacity utilization is constantly climbing.

The domestic RV reducer entered the scale of heavy volume. In the case of insufficient supply of foreign giants, the domestic reducer broke through the barrier of trust and initially sold volume in 2018. Among them, Nantong Zhenkang''s RV reducer has been supplied to Aft, Huanyan and other on-off enterprises in batches. Zhongdida has signed 80,000 orders with Bronte in 2018, and Double Ring Drive has signed 10,000 orders with Eft in 2018.

Fourth, the development trend of China''s reducer industry

In the 1970s and 1980s, the world''s reducer technology has developed greatly and is closely integrated with the development of the new technological revolution. The development trend of universal reducers is as follows:

1. High level and high performance: Cylindrical gears generally adopt carburizing and quenching, grinding teeth, and the bearing capacity is increased by more than 4 times. The volume is small, the weight is light, the noise is low, the efficiency is high, and the reliability is high;

2, building block combination design: the basic parameters use the priority number, the size specifications are neat, the parts are versatile and interchangeable, the series is easy to expand and the pattern is refurbished, which is conducive to organizing mass production and reducing costs;

3, the variety of types, variant design: get rid of the traditional single base installation, add hollow shaft suspension, floating support base, motor and reducer integrated connection, multi-directional mounting surface and other different types, expand the scope of use .

The main factors driving the increase of the speed reducer are:

(1) The theoretical knowledge is becoming more and more perfect, and it is closer to reality (such as gear strength calculation method, shape modification technology, deformation calculation, optimization design method, root smooth transition, new structure, etc.);

(2) With good materials, various high-quality alloy steel forgings are generally used, and the quality control level of materials and heat treatment is improved;

(3) The structural design is more reasonable;

(4) The processing accuracy is improved to ISO5-6;

(5) Improved bearing quality and life;

(6) The quality of lubricating oil is improved.

Since the 1960s, China has successively formulated the standards for a number of general-purpose reducers such as JB1130-70 "Cylindrical Gear Reducer". In addition to the self-supporting use of the main engine factory, it has also formed a number of professional manufacturers of reducers. There are hundreds of companies producing reducers nationwide, with an annual output of about 250,000 universal reducers, contributing to the development of China''s mechanical products.
