轴承甩油是ZQDR—204牵引电动机在日常运用中常见的惯性故障之一。我段1972年共发生大、小端轴承甩油落修的牵引电动机58台次,占落修电机总台数的55.2％,延长了机车检修停留时间,直接影响了运输任务的完成。我们认为造成轴承甩油的原因是多方面的:轴承室内积油过多、齿轮润滑脂通过电机密封圈串入轴承室内使轴承油脂稀释、原用二硫化钼与工业锂基脂或与其它油脂混装、二硫 Bearing oil throwing is one of the common inertial faults of ZQDR-204 traction motor in daily operation. In 1972, a total of 58 tractor motors with large and small end bearings thrown out of oil were repaired in 1972, accounting for 55.2% of the total number of motor repairs, thus prolonging the maintenance time of locomotives and directly affecting the completion of transportation tasks. We believe that the cause of bearing oil thrown away in many ways: too much oil inside the bearing chamber, gear grease into the bearing chamber through the motor seal to dilute the bearing grease, the original molybdenum disulfide and industrial lithium grease or other grease Mixed, disulfide
