Summary:...
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, a micro machine needs a compact gear transmission device composed of a micro motor and a micro planetary gear reduction unit, so that it has both driving and reduction 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. Structurally, 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 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. 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.
Planetary reducer application:
The reducer is a mechanical transmission device in many fields of the national economy. The product categories involved in the industry include various gear reducers, planetary gear reducers and worm reducers, as well as various special transmission devices, such as speed increasing devices and speed regulation Devices, and various composite transmission devices including flexible transmission devices. The product service area involves metallurgy, non-ferrous metals, coal, building materials, shipbuilding, water conservancy, electric power, construction machinery and petrochemical industries.
Lubrication of planetary reducer gears:
The problem of gear lubrication in gear transmission is an important issue in the development of miniature planetary gear transmission. Many scholars engaged in tribological research are working to better solve this problem. According to related documents, in general power transmission gear reducers, the smaller the diameter of the main shaft of the gear reducer, the greater the proportion of friction torque in the total power loss. However, in a micro machine, it is not easy to measure a small friction torque. However, the proportion of the friction torque of the miniature planetary gear reducer in its total power loss can be calculated and will increase. At present, people are paying special attention to the research work in the field of micro-tribology. It is expected that it can effectively solve the lubrication problem of the micro planetary gear reducer in the near future, and it plays a huge role in making the micro planetary gear reducer practical. Promoting role.
With the emphasis on the machinery manufacturing industry in the future, the demand for reducers by major companies continues to expand, so the use of reducers will accelerate the development of the entire power, construction machinery, building materials and energy industries. Naturally, the demand for reducers in this type of industry is also constantly expanding. It is expected that with the emphasis on the machinery industry, the production of reducers will also enter a white-hot stage, and only in this way can the market demand be met.
