According to the current situation analysis and Development Prospect Research Report of China's reducer industry in 2019-2025 released by China industry research network, domestic reducer 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 the scale ranging from the annual output value of several hundred million yuan to several million yuan. Experts predict that during the "11th Five Year Plan" period, due to the overall economic development of the country, the economic growth rate of the planetary reducer industry will still reach double digits.
The product categories involved in the reducer industry include gear reducer, cycloidal pin gear reducer, harmonic reducer, worm gear reducer, etc. Today, let's take a look at the development trend of planetary reducer and micro planetary gear reducer.
The planetary reducer realizes electromechanical integration:
In the micro machine, not only the micro transmission device that can transmit power - the micro planetary gear reducer, but also the micro planetary gear reducer that can bring its own power drive device is needed. In other words, the micro machine needs a compact gear transmission device composed of a micro motor and a micro planetary gear reduction unit, so that it has two functions of driving and reduction transmission. Therefore, the electromechanical gear transmission device with the above functions is characterized in that the input shaft and the output shaft of the micro planetary reducer are coaxial, and the motor shaft should be tightly connected with its load. Structurally, the shaft of the motor and the input of the planetary gear reducer can be connected, that is, the shaft of the motor and the gear shaft of the sun gear a are located on the same main axis line and connected to each other. And the output shaft of the planetary gear reducer (which is integrally connected with the internal gear E) is the output shaft of the assembly, thereby constituting an internal gear transmission device in which the motor and the planetary gear reducer are integrated. It can also be said that the motor and the planetary gear reducer are combined to form a low-speed motor, and its output shaft can be directly connected with the working machine. The current problem is that in order to make this kind of micro planetary gear reducer with motor practical, a practical micro motor similar to the size of the micro star reducer is required.
