Many customers will ask, what are the reasons for the noise problem of the bearing? As a manufacturer of angular contact ball bearings for 37 years, the following points are summarized: 1. Flutter caused by the change of the total number of loaded rolling elements When an axial load is loaded on a bearing, the number of rolling elements that bear the load is There will be a slight change in operation, resulting in a deviation of the load angle. 2. Partial damage A small part of the bearing dovetail guide and rolling elements are likely to be damaged due to incorrect operation or assembly. During operation, damaged bearing components develop corresponding vibration frequencies. Vibration frequency profiling identifies damaged bearing components. This mechanism has been used in condition monitoring equipment to detect bearing damage. 3. The precision of the relevant parts In the case that the inner and outer rings of the bearing are closely matched with the bearing seat or the middle of the rotating shaft, the inner and outer rings of the bearing may be deformed due to unreasonable cooperation with the appearance design of the adjacent parts. If deformation occurs, vibration and noise are likely to occur during operation. 4. Contaminants If the facility is operated in an environmentally polluted environment, there is a high possibility that residues will enter the bearing rolling elements and cause vibration noise. An annoying noise can often be heard with such things. 5. Other reasons The factors of noise caused by rolling bearings are more complicated. One is that the inner and outer surfaces of the bearings are damaged. Because of this type of damage, the matching relationship between the bearing and the housing, and the bearing and the shaft is destroyed, causing the centerline to be shifted to the proper position. Axle causes abnormal noise during fast fitness movements. In addition, if the bearing is not lubricated enough, dry friction and the crushing of the bearing will cause abnormal noises. If the bearing is damaged or the ball bearing is loose or damaged, it will also cause abnormal noise. The torque is accurate, in order to turn stable!
