Planetary gearbox tips and noise handling
skills
1. After 210~295 hours of operation, the planetary reducer should carry out the first replacement of the oil, and will check the quality of the oil from time to time in the later use. When the oil is too much impurities, the quality will drop. Under normal circumstances, for a planetary reducer that works continuously for a long time, it is necessary to replace the new oil once a year. The planetary reducer that has not been used for a long time should be replaced with new oil before re-running. The oil of the planetary reducer should be the same as the previous practical model of the oil.
2. When changing oil, wait for the planetary reducer to cool down without burning danger, but still keep warm, because after the cooling, the viscosity of the oil increases and it is difficult to drain. Note: The power supply of the transmission should be cut off to prevent unintentional energization;
3. During work, when it is found that the oil temperature rise exceeds 80 °C or the oil pool temperature exceeds 100 °C and abnormal noise is generated, stop using it. Check the cause, remove the fault, and replace the lubricating oil before continuing operation. ;
4. The user should have reasonable rules for the use and maintenance. The operation of the planetary reducer and the problems found in the inspection should be carefully recorded. The above provisions should be strictly implemented.
Noise treatment method
Most of the noise generated by the planetary reducer is due to the friction, vibration and collision of the transmission gear. How to effectively reduce and reduce the noise and make it more environmentally friendly is also a key research topic at home and abroad. Reducing the gear transmission noise when the planetary reducer is running has become an important research topic in the industry. Many scholars at home and abroad regard the change of gear tooth stiffness in gear transmission as the main factor of gear dynamic load, vibration and noise. The shape modification method is used to minimize the dynamic load and speed fluctuations to achieve the purpose of reducing noise. This method has proved to be a more effective method in practice. However, with this method, the process needs to have a shape-cutting device, and the majority of small and medium-sized factories are often unable to implement it.
