Factors that promote the increase in the level of planetary gear reducers

The factors that promote the improvement of the planetary gear reducer are as follows:
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, the use of good materials, the general use of a variety of high-quality alloy steel forgings, material and heat treatment quality control level.
3. The structural design is more reasonable.
4. The processing accuracy is improved to ISO5-6.
5, bearing quality and life expectancy.
6. The quality of lubricating oil is improved.
In recent years, the power of the planetary reducer designed and manufactured by China has reached 42000 kW, and the peripheral speed of the gear has reached 150 m/s or more. However, the technical level of most of the reducers in China is still not high, and old products cannot be replaced immediately. The transition of new and old products will take a long time.
