本文认为:导致钢领失效的磨损类型是热粘着磨损和摩擦疲劳磨损。粘着可分为两个时期,走熟期间的粘着是塑性接触引起的,而走熟后的粘着是“接触熔化”引起的。钢领工作表面的疲劳属于摩擦疲劳,而不是接触疲劳。摩擦疲劳磨损是摩擦力和温度脉冲长期作用的结果,而接触点上的切应力是引起这种破坏的主要原因。在出现摩擦疲劳磨损之前,存在着一个相当长的“潜伏期”。 This paper argues that the types of wear that lead to failure of the ring are thermal adhesive wear and frictional fatigue wear. Adhesion can be divided into two periods, ripening adhesion is caused by plastic contact, and cooked cooked adhesion is caused by “contact melting.” The fatigue of the working surface of the ring belongs to the friction fatigue, not the contact fatigue. Frictional fatigue wear is the result of friction and temperature pulse long-term effects, and the shear stress at the contact point is the main cause of this damage. There is a rather long “latency” before frictional wear occurs.
