1.泄漏的原因影响东风4型机车牵引电动机齿轮箱油封泄漏的因素很多,其中界面间隙的大小影响最大。就我段东风4型机车齿轮箱油封的泄漏来看,我认为关键是由于齿轮罩体的自然下垂和与电机组装的累计偏心,造成了油封与轴线的不同心。偏心不仅影响界面间隙,还影响毡条对轴(长毂面)的径向力、塑性、回弹力、浮动性和温度等。偏心越大,轴的径向活动量就越小,对罩体的振动就越大。在实际应用中常发生罩体裂纹和螺栓惯松的现象,并加速了顶
1. The reasons for the leakage Dongfeng 4 locomotive traction motor gearbox seal leak many factors, including the size of the interface gap greatest impact. I paragraph Dongfeng 4 locomotive gearbox oil seal leakage point of view, I think the key is due to the natural sagging gear cover and the cumulative assembly of the motor eccentric, resulting in the oil seal and the axis of the different hearts. Eccentricity not only affects the interfacial clearance but also affects the radial force, plasticity, resilience, floatability and temperature of the felt on the shaft (long hub). The greater the eccentricity, the smaller the radial movement of the shaft, the greater the vibration of the cover. In practical applications, the phenomenon of crack and bolt looseness often occurs and the roof is accelerated
