Causes of noise in rolling bearings

Writer: admin Time:2023-01-19 08:43 Browse:

(1) It is the wear of the matching surface of the inner and outer rings of the bearing. Due to this wear and tear, the matching relationship between the bearing and the housing, and the bearing and the shaft is destroyed, causing the axis to deviate from the correct position, and abnormal noise is generated when the shaft moves at high speed. When the bearing is fatigued, the metal on its surface will peel off, which will also increase the radial clearance of the bearing and produce abnormal noise.
 
(2) Insufficient lubrication of bearings, dry friction, and broken bearings will produce abnormal sounds.
 
(3) After the bearing is worn and loose, the cage is loose and damaged, which will also cause abnormal noise and damage to the bearing. When the rolling bearing is disassembled and inspected, the failure of the bearing and the cause of the damage can be judged according to the damage of the bearing.
