When a bearing is subjected to a radial load, it experiences both a loaded zone and a non-loaded zone. If the bearing has a certain amount of radial clearance, the rolling elements in the non-loaded zone may not be fully supported. In such cases, the centrifugal force alone might cause the rolling elements to come into contact with the inner race or the cage.
At low speeds, where the centrifugal force is less than the weight of the rolling elements, the rolling elements can fall out of place, leading to an unstable motion and increased noise. This phenomenon, often referred to as "bearing tumbling," exhibits several characteristics:
1. The occurrence of this issue varies depending on the speed and the size of the bearing.
2. It is more likely to happen when there is a large radial clearance and only a radial load is applied.
3. The noise produced may be intermittent or irregular.
4. Bearings are more prone to this problem when using grease rather than oil, especially if the grease is too thick.
5. The effect tends to be more noticeable during start-up or under varying loads.
6. The vibration caused by this issue can lead to secondary oscillations in the outer ring, which may affect the overall performance of the bearing.
Understanding these behaviors is essential for maintaining the efficiency and longevity of bearings in various mechanical systems.
