Light weight, compact, high-strength, high-reliability and so on have been required to machines, therefore highly reliable evaluation and verification as well as improvement of surface durability is one of the most important subjects. In this study three dimensional contact stress analyses was conducted in considering of both macro-configuration such as crowning and micro-configuration such as asperity, hardness, and residual stress distributions, and the surface failure and durability were evaluated. The surface failure and durability were also examined and evaluated with rollers and gear pairs with various micro and macro surface configurations.As to surface macro-configuration, the influence of crowning on surface durability and traction performance was investigated. In case that no edge load or minor edge load occurred, the rolling contact fatigue strength evaluated with the normal load increased with increasing crowning radius. On the contrary, the traction performance increased with decreasing crowning radius. It was clarified that the optimal crowning, where both the high rolling contact fatigue strength and the traction performance were combined, exists and the importance of the crowning design of the power transmission tribomachine elements.As to micro-configuration, hardness distribution, residual stress distribution, and surface roughness of rollers and gear pairs with shot-peening, double shot-peening, and some other treatments such as cavitation shotless peening were measured. The amplitude of the ratio of the stress to the hardness obtained by the contact analyses in consideration of hardness distribution and residual stress distribution measured would be suitable for evaluation of the surface durability and the fatigue life.

对机械设备提出了轻量化、紧凑化、高强度、高可靠性等要求，因此，对表面耐久性进行高可靠性的评价和验证以及提高表面耐久性是重要课题之一。在这项研究中，进行三维接触应力分析，考虑到宏观结构，如冠状和微观结构，如粗糙度，硬度和残余应力分布，和表面失效和耐久性进行了评估。对不同微观和宏观表面形貌的滚子和齿轮副的表面失效和耐久性进行了测试和评价，并对表面宏观形貌进行了研究，分析了凸度对表面耐久性和牵引性能的影响。在没有边缘载荷或边缘载荷较小的情况下，用法向载荷评估的滚动接触疲劳强度随着凸度半径的增加而增加。相反，牵引性能随着冠状半径的减小而增加。阐明了动力传动摩擦机械零件存在着既能获得高的滚动接触疲劳强度又能获得高的牵引性能的最佳凸度，以及凸度设计的重要性。并进行了空蚀喷丸等其它处理。考虑到测量的硬度分布和残余应力分布，通过接触分析获得的应力与硬度的比值的幅值将适合于评估表面耐久性和疲劳寿命。
