机械设备在使用中经常出现轴承跑图，有的是轴承内圈与轴松动，有的是轴承外圈与座孔松动。由于间隙很小，始终没有很好的解决办法，一直是机床维修工最棘手的问题。 宁夏机械工程学会粘接分会研究出一种简便、快速、可靠的专治轴承跑圈的技术，已列为国家“金桥工程”项目，在 Mechanical equipment in use often bearing running map, some are bearing inner ring and shaft loose, some bearing outer ring and seat hole loose. Due to the small gap, there has always been no good solution, which has been the thorniest problem for machine tool repair workers. Ningxia Mechanical Engineering Society Branch has developed a simple, fast and reliable technology-based bearing ring race has been listed as the national “Golden Bridge Project” in the
