Bearing damaged cause and the use of the common matters needing attention

Bearing the damage to the common cause and the matters needing attention of the general terms, a third of the bearing damage resulting from the fatigue damage, a third of the other resulting from poor lubrication, a third of the other resulting from improper disposal of pollutants into the bearing or installation. However, the damage pattern is also related to industrial don't. Pulp and paper industry, for example, mostly due to bad lubrication or pollution of bearing damage, not due to material fatigue. For bearing equipment preventive maintenance, operation and peripheral parts change was removed when high temperature bearing aborted inspection, demand, in turn, discriminant can bearing parts can be used again and record use case better than bad. More serious investigation and record the bearing and the appearance of being removed. In order to explore the residual amount of investigation and lubricant, after sampling, to clean the bearing well. Second check bearing raceway surface, rolling surface and cooperate with the surface conditions and adhere to the wear conditions of with and without damage to watch the race and abnormal situation especially the running track. Discriminant bearing can use again, the extent of the damage will be thinking of bearings, machine performance, importance, and operating conditions, such as inspection cycle resolution will come later. Inspection result, suppose that there are found bearing damage and abnormal situation, please according to the bearing damage phenomenon to find out the reason, formulate countermeasures. In addition, the test results, there are some defects, assuming that the bearing can't use, need to change the new bearing. 一个。 Inner and outer ring, rolling body, adhere to any of them have crack and present pieces. b。 Inner and outer ring, rolling body any one strip. c。 Raceway surface, guard, significant injury of roller. d。 Insist on plane badly worn or loose rivet fierce. e. Raceway surface, rust and roller has a scar. f。 Had a remarkable indentation rolling surface, rolling body and make a mark. g。 Inner ring diameter or outer diameter on the creep. h。 Hot color changing fierce. 我。 Sealed bearing grease sealing and dust cover breakage to serious.
