摘要
对洛阳机务段HX_D3机车牵引电机NU330轴承运用中的问题进行了调查,对调查中还未出现故障的轴承内套滚道面出现的初始裂纹进行了全面材料检验,分析认为该轴承早期失效的原因是轴承内圈滚道面局部承受了较高的接触应力所致。
In this paper,the traction motor NU330 bearings＇ application problems of HX_D3 electric locomotives allocated in Luoyang Locomotive Depot are investigated,the comprehensive material inspection is conducted for the initial crack of no-fault bearings inner raceway surface,and the cause of bearing premature failure is confirmed that the bearing inner ring raceway surface has suffered higher contact stress.
