What is the bearing movement
Bearing a rotation, the inner race and the outer raceway surface, due to rolling contact with the rolling element, so the running track is dark, running track attached to the raceway surface does not belong to the exception, so remove the SKF bearings, please Pay strict attention to and observe the running track of the raceway. Careful observation of the operating path reveals that only the radial load, the large axial load, the moment load or the extreme rigidity of the bearing housing is unequal. Can check whether the bearing plus the accidental load and installation error is too large, etc., and became the clues to investigate the cause of bearing damage. Out of deep groove ball bearings in different load conditions of production running track. (A) is the normal operating path that can only support radial loads when the inner ring is rotating. (C) ~ (h) shows the trajectory of the bearing has a bad influence, most of the service life is relatively short. The same applies to roller bearings. (I) The outer ring travel path when a cylindrical roller bearing used in rotating the inner ring is correctly loaded with a radial load. (J) is the relative inclination of the inner ring and the outer ring, the axis of deflection of the larger trajectory, raceway surface trajectory, in its longitudinal shades at the load ring exit, the trajectory is inclined, double cone Roller bearings rotate the inner ring. (K) shows the running path of the outer ring when only the radial load is applied. L represents the path only under axial load. When the inner ring and the outer ring are relatively inclined to bear the radial load only, the operation track deviates from the two track surfaces 180. s position.
