在同一条轴线上一根轴插入另一根轴端中心孔内(见附图)的对接轴,主要损坏形式是连接部分轴颈与轴中心孔的磨损与烧蚀。轴颈与轴孔之间有一周滚针,与滚针接触的表面非常坚硬,通常为HRC60左右。其损坏的原因主要是润滑不良。第一种修理方法是,将旧轴的轴颈与轴孔修圆,根据受力及转速情况另选相应的滚针轴承安装在轴颈与轴孔之间,仍可继 In the same axis, a shaft is inserted into the center shaft of the other shaft end (see the attached drawing). The main damage form is the wear and ablation of the journal and shaft center hole in the connecting part. There is a rolling pin between the journal and the shaft hole, and the contact surface with the rolling pin is very hard, usually around HRC60. The main reason for the damage is poor lubrication. The first method is to repair the shaft and shaft axis of the old shaft rounded, depending on the force and speed of the situation alternatively the corresponding needle roller bearings installed between the journal and shaft hole, still following
