(1). Insufficient bearing lubrication, dry friction, and bearing crushing will produce abnormal sounds.
(2). It is the wear of the inner and outer rings of the bearing. As a result of this wear, the bearing and the housing, the bearing and the shaft are broken, causing the axis to deviate from the correct position and produce an abnormal sound when the shaft is moving at a high speed. When the bearing is fatigued, the surface metal peeling off will also increase the radial clearance of the bearing to produce abnormal noise.
(3). After the bearing wears loose, the cage is loose and damaged, and the abnormal bearing damage will also occur. When the rolling bearing is disassembled and inspected, the bearing failure and the cause of damage can be judged according to the damage of the bearing.
