According to the report on the current situation analysis and development prospects of China's gearbox industry from 2019 to 2025 released by China Industry Research Network, domestic gearbox manufacturers also coexist in various forms, such as foreign-funded enterprises, Sino foreign joint ventures, state-owned enterprises, joint-stock enterprises, and individual enterprises, with scales ranging from hundreds of millions of yuan or more in annual output value to millions of yuan. It is predicted that during the 11th Five Year Plan period, due to the overall economic development, the growth rate of the planetary gearbox industry's total economic output will still reach double digits.

The product categories involved in the reducer industry include gear reducers, cycloidal pinwheel reducers, harmonic reducers, worm gear reducers, and so on. Today we will take a look at the development trend of planetary gear reducers and micro planetary gear reducers.

Planetary gearbox achieves mechatronics integration:

In micro machines, not only is there a need for a micro transmission device that can transmit power - a micro planetary gear reducer, but also a micro planetary gear reducer that can have its own power drive device. In other words, micro machines require a compact gear transmission device composed of micro motors and micro planetary gear reducers, enabling them to have both driving and deceleration functions. Therefore, for the electromechanical integrated gear transmission device with the above functions, its feature is that the input shaft and output shaft of this micro planetary reducer have coaxiality, and the motor shaft should be compactly connected to its load. Structurally, the shaft of the electric motor can be connected to the input of the planetary gear reducer, that is, the shaft of the electric motor and the gear shaft of the sun gear a are located on the same main axis and are interconnected. The output shaft of the planetary gear reducer (integrated with the internal gear e) is the output shaft of the combination, thus forming an internal gear transmission device that integrates the electric motor and the planetary gear reducer. It can also be said that the electric motor and planetary gear reducer are combined to form a low-speed electric motor, and its output shaft can be directly connected to the working machine. The current problem is that in order to make this micro planetary gear reducer with an electric motor practical, it is necessary to have a practical micro electric motor that is similar in size to the external dimensions of the micro planetary gear reducer.

Application of planetary gearbox:

Reducer is a mechanical transmission device in many fields of the national economy. The product categories involved in the industry include various types of gear reducers, planetary gear reducers, and worm gear reducers, as well as various specialized transmission devices such as speed increasing devices, speed regulating devices, and various composite transmission devices including flexible transmission devices. The product and service fields involve industries such as metallurgy, non-ferrous metals, coal, building materials, shipbuilding, water conservancy, electricity, engineering machinery, and petrochemicals.

With the increasing emphasis on the mechanical manufacturing industry in the future, the demand for reducers from major enterprises is constantly expanding. Therefore, the utilization of reducers will accelerate the development of the entire power, construction machinery, building materials, and energy industries. Naturally, the demand for reducers in such industries is also constantly expanding. It is expected that with the increasing emphasis on the machinery industry, the production of reducers will enter a white hot stage, and only in this way can the market demand be met.
