1. Partial damage due to operation or device fault; a small part of the bearing raceway and the roll body can be damaged. During operation; a specific oscillation frequency occurs when rolling over the damaged bearing component. The oscillation frequency can be analyzed. Identify damaged bearing components. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
2. The oscillating action in the use case is in many uses; 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; Have the ability to reduce the oscillations in use.
3. The waviness of the component is in close cooperation between the bearing ring and the bearing seat or the drive shaft; the bearing ring can be deformed in cooperation with the shape of the adjacent component. 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.
There are three ways to reduce the oscillation:
1. The resistance between the stimulating component and the resonant component is encouraged to oscillate.
2. Change the stiffness of the layout; then change the critical frequency.
3. Remove the critical encouragement oscillation from use.
