Do you know why bearing used in damage?

1, damage to the bearings, main reasons are: data tired; Smooth bad; Pollution; Equipment problem; Handled properly. In general, a third reason is that material fatigue damage; A third is smooth and bad; Another third is pollutants enter the bearing or device is handled properly. 2, the beginning of the bearing damage: bearing from began to apply to the exhaustion of the first data point rendering time length, and this period of time of revolution, and the size of the load bearing, smooth, and cleanliness. Fatigue load is under the result of the shear stress of periodic present, after a period of time, will trigger a tiny crack, then gradually extends to the appearance. When the roll body after the crack of small area, some crack block begin to fall off, constitute the so-called peeling phenomenon, as the skinning continue to expand, bearing damage cannot be used. Begin to occur under the appearance, although start peeling generally very subtle, but increased with the increase of stress and crack block, lead to the spread of the peeling area, the process to continue for a long time, generally significant during the period of oscillation and noise, so before not bad, should have enough time to replace it. 3 general bearing, the stress of the bearing traces after a period of time in a job assignment, the homework appearance brings a significant stress trace, not all traces of the present it means the bearing is broken, bearing used in normal circumstances they leave traces of forces. Bearing work under load, the contact surface of raceway in appearance with dark hair black. But this is not said wear, at the same time also has nothing to do with life. The trace of the crocking structure became bearing force, along with their work and load conditions, the trace its appearance also each are not identical, carefully view can help us to determine whether a bearing work under normal conditions. Centripetal bearing, ball bearing, spherical, double row ball only accept radial force, able to bear a small amount of axial load, damage way is often caused by excessive axial force. ( 1) Radial load, one-way: two kinds of conditions, is a kind of inner ring spinning; One is the inner ring is fixed. ( 2) , one-way axial load: the inner or outer ring spinning. ( 3) , one-way radial load and axial load combination. ( 4) , radial load, and the inner ring synchronous rotation, the outer ring is fixed. ( 5) , radial load and the outer ring synchronous rotation, the inner ring is fixed.
