HXD2型新八轴机车在安康机务段担当牵引任务以来,陆续发生轮对踏面剥离现象,在厂、验、段三方的共同努力下,通过跟踪对比轮对踏面状态变化情况以及统计分析相关数据,提出了引起轮对踏面剥离的主要原因和解决措施,经长时间的运用考核,效果良好,实践证明剥离问题得到有效解决。 Since the HXD2 new eight-axis locomotive has taken on the traction task of Ankang Locomotive Depot, the wheel-tread surface stripping occurs one after another. With the joint efforts of the factory, inspection and segment tributaries, by tracking and comparing the wheelset tread condition changes and the statistical analysis data, The main reason that caused the separation of wheel tread and its countermeasures were put forward. After a long period of application and examination, the effect was good. The practice proved that the problem of delamination was effectively solved.
