Требования к техническому обслуживанию для поддержания чистоты подшипников

Due to the relative movement of the rolling elements and the raceways and the intrusion of pollutants and dust, the surfaces of the rolling elements and the raceways are worn. When the amount of wear is large, the bearing, noise and vibration increase, which reduces the running accuracy of the bearing, thus directly affecting the accuracy of some hosts. Therefore, for some bearings for silent machinery, routine maintenance is mainly to prevent the intrusion of pollutants and dust.

1. Impact on bearing life

The cleanliness of the bearing has a considerable impact on the life of the needle bearing. The bearing has been specially tested for this purpose. The result is that the difference is several times or even dozens of times. The higher the cleanliness of the bearing, the longer the life. Tests by others have shown that different degrees of cleanliness of the lubricant have a great impact on the life of the ball bearing. Therefore, improving the cleanliness of the lubricating oil can prolong the life of the bearing. In addition, if the dirt particles in the lubricating oil are controlled below 10um, the bearing life will also increase several times.

2. Impact on vibration and noise

The test results of the bearing test center show that cleanliness seriously affects the vibration level of the bearing, especially in the high frequency band. Bearings with high cleanliness have low vibration velocity values, especially in high frequency bands. Experiments have been conducted on the effect of dust in needle bearing grease on noise, which proves that the more dust, the greater the noise.

3, The impact on lubrication performance Decreased bearing cleanliness will not only affect the formation of lubricating oil film, but also cause the deterioration of the grease and accelerate its aging, which will affect the lubrication performance of the grease.
