if found bearing damage and abnormal situation
2013-11-04 by seoer4
SKF bearings fatigue testing machine equipment for regular maintenance, operation and external parts replacement bearings were removed for inspection, required in order to determine whether this bearing parts can be used again and record usage of good and bad. Should carefully investigate and record split down the bearing and appearance of the situation. In order to understand and investigate remaining amount of lubricant, after the sampling, to a good wash bearings.
Second, check the SKF bearing raceway, rolling surface and the mating surface of the situation and the state of wear of the cage and other signs of damage and anomalies in particular, to observe the raceway running track. Determine the bearing can be used again, to consider the extent of bearing damage, machine performance, the importance of operating conditions, inspection cycles and then later decide.
Test results, if found bearing damage and abnormal situation, please follow identify the reasons for the phenomenon of bearing damage, develop countermeasures. In addition, test results, if there are several flaws words below, bearing it can not be used again, you need to replace the bearings.
a. inner and outer rings, rolling fatigue testing machine elements, cage cracks and any one of them will be fragmented.
b. inner and outer rings, rolling elements of any one of a release.
c. raceway, ribs, rolling a significant injury card.
d. cage badly worn or loose rivets terrible.
e. raceway, rolling rust and have scars.
f. rolling surface, rolling on and playing a significant indentation marks.
g. inner diameter surface or outer diameter on the creep.
h. overheating discoloration powerful.
i. grease seals and dust sealed bearings to severe damage.
