摘要
构架螺纹孔的状态与轨道车辆的行驶稳定性息息相关,螺纹孔的状态不好甚至会影响行车安全,造成意外事故。针对构架螺纹孔检修的重要性,简要介绍了近几年构架检修的情况,对螺纹孔损坏原因进行了剖析,阐述了构架螺纹孔检修的加工工艺,结合作者多年构架检修实践经验,分析了焊修法和钢丝螺套法修复工艺的适用条件,对构架修理通用性工艺进行了总结。
The state of the threaded hole of bogie is closely related to the running stability of the rail vehicle,whose bad function may even affect the safety of the traffic, causing serious accidents. Focusing on the importance of its maintenance,this paper briefly introduces the situation of bogie maintenance in recent years,and analyzes the causes of damages occurred in the threaded hole, and also the maintenance processing technology of the threaded hole of bogie is described. Based on several years of practical experience in bogie maintenance of the author, the applicable conditions of welding repair method and wire thread inserts repair technology are analyzed, and the general process of bogie repair is summarized.
