What is the prospect of planetary reducer

　　According to the 2019-2025 China Reducer Industry Status Analysis and Development Prospects Research Report released by the China Industry Research Network, the production of the domestic reducer industry also coexists in various forms, such as foreign-funded enterprises, Sino-foreign joint ventures, state-owned enterprises, and joint-stock enterprises. And individual enterprises, ranging from as large as several hundred million yuan in annual output value to as small as several million yuan.Experts predict that during the "Eleventh Five-Year Plan" period, due to the development of the country's overall economy, the growth rate of the total economic volume of the planetary reducer industry will still reach double digits.

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

　　Planetary reducer realizes mechatronics:

　　In a micro machine, not only a micro transmission device that can transmit power-a micro planetary gear reducer, but also a micro planetary gear reducer with its own power drive device is required.In other words, the micro machine needs a compact gear transmission device composed of a micro motor and a micro planetary gear reducer unit, so that it has both driving and deceleration transmission functions.Therefore, the mechatronic gear transmission with the above-mentioned functions is characterized in that the input shaft and the output shaft of the miniature planetary reducer have coaxiality, and the motor shaft should be tightly connected with its load.In terms of structure, the shaft of the motor can be connected with the input of the planetary gear reducer, that is, the shaft of the motor and the gear shaft of the sun gear a are located on the same main axis and are connected to each other.The output shaft of the planetary gear reducer (connected as a whole with the internal gear e) is the output shaft of the combined body, which constitutes a built-in gear transmission in which the electric motor and the planetary gear reducer are combined into one body.It can also be said that the motor and the planetary gear reducer are combined into a low-speed motor, and its output shaft can be directly connected to the working machine.The current problem is that, in order to make the miniature planetary gear reducer with electric motor to be practical, it is necessary to have a practical miniature motor with the same size as the miniature star reducer.
