Generally speaking, international cutting-edge bearings such as SKF bearings do not attack. Once they have attacked, they should be checked. The excitation caused by the change of the number of loading tumblers is a radial load loading. In the case of a bearing; the number of tumbling bodies carrying the load will be slightly changed during operation; that is, this causes a shift in the direction of the load. The resulting oscillation is unavoidable; but it can be axially preloaded. Reduced; loaded on all roll bodies (not applicable to cylindrical roller bearings). The waviness of the part is in close cooperation between the bearing ring and the bearing seat or the drive shaft; the bearing ring has the ability to cooperate with the shape of the adjacent part Deformation. If it is deformed, it can oscillate during operation. Therefore, it is important to machine the bearing housing and the drive shaft to the required public service. Partial damage is due to operation or device fault; small part of bearing raceway and tumbling The body can be damaged. During operation; a specific oscillation frequency occurs when rolling over the damaged bearing component. The oscillation frequency profile can identify the damaged bearing component. The oscillation action in the use case is In use; the stiffness of the bearing is the same as the stiffness of the surrounding layout. Because of this feature; only the correct selection of bearings (including preload and clearance) and their equipment in use; there is the ability to reduce the oscillations in use. There are three The method can reduce the oscillation: remove the critical encouragement oscillation from the use, suppress the critical excitation oscillation between the excitation component and the resonance component, change the stiffness of the layout; then change the critical frequency.
