摘要
介绍了CRH1型动车组空心轴探伤作业过程中发现的轴端螺栓断裂、轮对轴承甩脂、轴端锈蚀等问题,重点分析了问题产生的工艺原因,并提出了解决方案。
Such problems found in the process of flaw detection on hollow axles of CRH1 multiple units as breaking of axle end bolts,grease throwing out of wheelset bearings and axle end rust are described.The causes to the problems are mainly analyzed in technology.And the scheme for solution is given.
