Summary of angular contact ball bearing manufacturers: factors affecting bearing noise-

Many customers will ask, what are the reasons for the noise of the bearing? As a manufacturer of angular contact ball bearings for 37 years, Sanli has summarized the following points: 1. Flutter caused by changes in the total number of loaded rolling elements When an axial load is loaded on a certain bearing, the number of rolling elements bearing the load It will change slightly during operation, resulting in a deviation of the load angle. 2. Partial damage A small part of the bearing dovetail guide and rolling elements is likely to be damaged due to incorrect handling or assembly. During operation, damaged bearing components will form a corresponding vibration frequency. Vibration frequency profiling can identify damaged bearing components. This mechanism has been used in condition monitoring equipment to detect bearing damage. 3. The precision of related parts In the case of close fit between the inner and outer rings of the bearing and the bearing housing or the rotating shaft, the inner and outer rings of the bearing may be deformed due to improper fit with the appearance of the adjacent parts. If deformation occurs, vibration and noise may occur during operation. 4. Pollutants If the equipment operates in a polluted environment, debris may enter the rolling elements of the bearings and cause vibrations. Such things can often be heard as an annoying noise. 5. Other reasons The factors causing noise of rolling bearings are more complicated. One is that the inner and outer surfaces of the bearing are damaged. Due to this kind of damage, the matching relationship between the bearing and the housing, and the bearing and the shaft is destroyed, causing the center line to deviate from the correct position. Axis causing rattling during fast gym movements. In addition, if the bearing is not lubricated enough, dry friction will occur, and abnormal noise will inevitably occur if the bearing is crushed. Damaged bearings, loose ball bearings and damaged ball bearings can also cause abnormal noise. Only when the torque is accurate can the rotation be stable!
