KOYO bearing assembly improper cooperate clearance with fault detection

KOYO bearing as the main components Material Of SKF Bearings of the locomotive, especially the traction motor and axle box KOYO bearing, its function plays an important role in transportation safety, the locomotive runs, online once KOYO bearing failure, will cause the whole trains can not run, blocking transportation trunk line, especially the passenger train fails, the negative impact is bigger, once the locomotive KOYO bearing failure occurs at the same time, the locomotive repair is very difficult, so the prevention and decrease of locomotive KOYO bearing failure, transportation is very important to the security of locomotive, can will have the problems before the KOYO bearing loading KOYO bearing.
KOYO bearing damage is often not a single reason, but under the effect of several aspects comprehensive, under harsh operating conditions to produce vicious circle, causes severe loss of KOYO bearing, so after the accident, it is often difficult to determine is caused by what, also bring some difficulties to our relevant measures, convenient for discussion, first from several aspects to analyze the cause of KOYO bearing failure .
Use after a period of time when KOYO bearing, KOYO bearing inner ring, rolling element and cage, outer ring raceway produce certain defects, such as scars, KOYO bearing caused by poor lubrication, cause the fever of KOYO bearing, fever for a long period of time, can lead to: (1) the KOYO bearing lubricating oil dilution. (2) accelerate the fatigue of material, hardness decreased. Due to these reasons, and further form vicious circle, accelerated overheating and make the KOYO bearing damage. Serious displacement of KOYO bearing inner ring, rolling body round, heating, welding together in the end. So in the online operation, such as found KOYO bearing severe fever, smoke, don't stop, and should keep running to stand ahead, because this moment overheating KOYO bearing in melting state, once the parking is unable to walk again after cooling, main blockage.
