Air compressor bearingsIt is a very important part of air compressor, and the running time increases with the use of air compressor。The air compressor will make noise from the air compressor bearing, so what are the causes of the air compressor bearing noise？

1, local damage Due to operation or installation errors, a small part of the air compressor bearing raceway and rolling element may be damaged。During operation, damaged bearing components produce specific vibration frequencies。Vibration frequency analysis can identify damaged air compressor bearing components。This principle has been applied to condition monitoring equipment to monitor the damage of air compressor bearings。

2. Excitation caused by changes in the number of loaded rolling elements When a radial load is loaded on an air compressor bearing, the number of rolling elements bearing the load will change slightly during operation, causing the load direction to shift。

3, pollutants If the equipment is operated in a polluted environment, impurities may enter the air compressor bearing rolling body, resulting in vibration sound。In this case, a disturbing noise can usually be heard。

4, air compressor bearing wear, cage loose damage, will also produce abnormal sound。

5、 In the case of close coordination between the inner and outer rings of the air compressor bearing and the bearing seat or the drive shaft of the air compressor, the inner and outer rings of the air compressor bearing may be improperly matched with the shape of the adjacent parts and be deformed。If deformation occurs, vibration and noise may occur during operation。

6. The causes of noise generated by other rolling air compressor bearings are more complex, one is the wear of the inner and outer rings of air compressor bearings。Due to this wear, the mating relationship between the air compressor bearing and the housing and the air compressor bearing and the shaft is destroyed, resulting in the axis deviating from the correct position。The shaft produces abnormal sound when moving at high speed。
