苏联罗斯托夫铁道学院提出了一种提高机车牵引电动机抱轴承可靠性的方法,即在其摩擦表面上刻划出一些大沟槽,但是这些沟槽不延伸到轴瓦的端部。经过这样加工的抱轴承与目前批量生产的、具有光平摩擦面的抱轴承相比,前者可以在摩擦面上储存大量的润滑材料。这样就可以改善抱轴承的工作条件,提高抱轴承的工作能 The Rostov-on-Tire Institute of the Soviet Union proposed a method of increasing the reliability of the locomotive traction motor bearings by scribing a few large grooves in the friction surfaces but these grooves did not extend to the ends of the bush. After this processing of the bearing and the current mass production, with a smooth flat-faced friction bearing, the former can be stored in the friction surface of a large number of lubricating materials. In this way, the working conditions of the bearing can be improved and the working ability of the bearing can be improved
