机车车辆车轴、汽车车轴、船舶螺旋桨轴、发电机及电动机电枢轴、大型曲轴等采用的压装轴,其疲劳强度比光滑轴低得多,因此有必要综合考虑尺寸效应、缺口效应、微动磨蚀的向题。微动磨损是由于螺栓连接处和压装或热装轴、滚动轴承等承受到交变载荷的机械构件,在其压入部位出现微小的相对滑动而发生的,这种磨损引起的尺寸精度下降、’疲劳裂纹发生等导致了疲劳强度降低,成为一个重要的研究课题。本文整理了压装与微动疲劳强度的有关资料,最大限度地收集了能在设计中应用的内容。关于压入轴的设计,以前已有文章介绍,故本文主要着重于其表面处理方面的介 The fatigue strength of rolling axles, locomotive axles, automobile axles, ship propeller shafts, armature shafts of generators and motors, large crankshafts, etc., is much lower than that of smooth shafts. Therefore, it is necessary to consider the size effect, Move to the problem of erosion. Fretting wear is due to bolt connections and press-fitted or hot-loaded shaft, rolling bearings and other subjected to alternating load of mechanical components, in the press-in parts of the small relative sliding occurs, the wear caused by the decline in dimensional accuracy, ’Fatigue cracks have led to the reduction of fatigue strength has become an important research topic. This article has sorted out the information about the fatigue strength of press fit and fretting, and collected the content that can be applied in the design to the maximum. On the design of the press into the shaft, the article has been introduced before, so this article focuses on the surface treatment of its introduction
