轴承是机车牵引电机的重要部件,也是极易发生故障的部件之一。通过对电机轴承故障的分析,兼顾诊断参数敏感性与稳定性的特点,研究了结合振动加速度有效值和峭度系数的轴承故障振动综合检测法,同时辅以轴温检测的实时监测,可以有效地预防、监测机车牵引电机的轴承故障。提出了牵引电机轴承的日常保养与故障预防措施,在一定程度上减少牵引轴承的故障率,保障机车的行车安全。
Bearings are an important part of locomotive traction motors and one of the most vulnerable parts. Based on the analysis of the motor bearing faults and the sensitivity and stability of the diagnostic parameters, a comprehensive bearing vibration detection method based on the effective value of the vibration acceleration and the kurtosis coefficient is studied, and simultaneously with the real-time monitoring of the shaft temperature detection, it is effective To prevent, monitor locomotive traction motor bearing failure. Put forward the routine maintenance of traction motor bearings and fault prevention measures to reduce the failure rate of traction bearings to a certain extent, to protect the locomotive traffic safety.
