牵引电动机轴承外圈外表面涂覆有PPS绝缘树脂的PPS绝缘轴承正广泛应用于铁道车辆。采用实物牵引电动机实施了轴承温升试验,试验结果从理论上定量地揭示了PPS绝缘轴承的特性,指出严格地进行润滑脂量的管理是至关重要的。
Traction motor bearing outer surface coated with PPS insulating resin PPS insulated bearings are widely used in railway vehicles. The bearing temperature rise test was carried out with the actual traction motor. The test results theoretically quantitatively revealed the characteristics of the PPS insulated bearings and pointed out that the strict management of the grease quantity is of utmost importance.
