(Summary description)Maintenance and judgment of bearing
In order to judge whether the disassembled bearing can be used, it should be checked after the bearing is cleaned. Check the state of raceway surface, rolling surface and mating surface, the wear of cage, the increase of bearing clearance and the damage of irrelevant dimensional accuracy, which are abnormal. For non separable small ball bearings, support the inner ring horizontally with one hand and rotate the outer ring to confirm whether it is smooth.
(1) Tapered roller bearings and other separate bearings can inspect the raceway surfaces of rolling elements and outer rings respectively.
(2) Since large bearings cannot be rotated by hand, pay attention to the appearance of rolling elements, raceway surfaces, cages, edge retaining surfaces, etc. the higher the importance of bearings, the more careful the inspection is.
Judgment of whether the bearing can be reused (bearing replacement)
It is determined by considering the degree of bearing damage, mechanical performance, importance, operating conditions and the period until the next maintenance. However, if there are the following defects, they can no longer be used and must be replaced with new bearings.
(1) There are cracks or notches on any one of the inner ring, outer ring, rolling element and cage
(2) Any one of the ferrule and rolling element is broken
(3) There is significant jamming on the raceway surface, retaining edge and rolling element
(4) Significant wear of cage or significant relaxation of rivets
(5) There is rust and damage on the raceway surface and rolling element
(6) There are serious indentations and scratches on the raceway surface and rolling element
(7) There is obvious creep on the inner diameter surface of the inner ring or the outer diameter surface of the outer ring
(8) Discoloration caused by heat is obvious
(9) The bearing, sealing ring or dust cover sealed with grease is obviously damaged
Strengthening the maintenance and identification knowledge can not only effectively reduce the equipment failure rate, reduce the maintenance cost and the number of spare parts, but also greatly reduce the downtime and improve the economic benefits of enterprises, which is of great significance to further improve the equipment management!
