Common problems of planetary reducers and how to maintain them

The common fault of precision planetary reducers is wear and tear,
mainly covering the following parts:
First, the bearing wear of the planetary reducer;
Second, the gear shaft diameter of the planetary reducer is worn, among which the shaft head and keyway parts are very easy to wear seriously;
Third, the bearing of the transmission shaft of the planetary reducer is worn;
Fourth, the mating surface of the planetary reducer is worn.

Usually, the traditional method adopted by enterprises for wear problems is to repair the wear parts by welding and processing after brush plating. However, this method has a significant disadvantage, that is, it is time-consuming and labor-intensive, and may not ensure its sealing effect, and it is necessary to suspend the operation of the machinery, which not only affects the production efficiency of the enterprise, but also causes unnecessary economic losses.
Therefore, in order to improve the work efficiency of the enterprise and the service life of the precision planetary gear reducer, and to ensure the normal operation of the working machinery, it is necessary to pay attention to its maintenance and maintenance in the daily operation of the planetary reducer.

The maintenance method is simple and easy, without any technical difficulty, and does not require too much time and energy. You should collect it quickly.

First, it is necessary to pay attention to the working time of the planetary gear reducer to avoid the reducer running for too long, exceeding the reducer's own bearing capacity, resulting in increased workload, machine heating, and affecting the service life. The general service life of the planetary precision reducer is 20,000 hours, depending on the actual working conditions of the reducer and daily maintenance.

Second, select appropriate lubricating grease according to the type and model of the working machine of different enterprises, and check the oil volume and the sealing of the machine regularly.

Third, clean the planetary reducer regularly to check whether there are loose or worn parts.

Fifth, bearing lubrication For the lubrication of rolling bearings in reducers, commonly used lubricants are lubricating oil and grease. When choosing lubricating oil, factors such as bearing load, speed, temperature, and working environment need to be considered. The higher the bearing load and the higher the temperature, the higher the viscosity of the lubricating oil. When the bearing load is small, the temperature is low, and the speed is high, low-viscosity lubricating oil can be used.
