摘要： PROBLEM TO BE SOLVED: To solve the problems wherein so as to fit by caulking, both end parts of stem, it is needed to prevent them from being nitrided, if each stem is subjected to nitriding prevention using a method for covering only both the end parts of the stem with a nitriding prevention agent, it takes a long time to perfrom the processing, it is considered inefficient to do so, and also both the high-hardened end parts remaining nitrided in an unsuitable state for caulking are subjected to caulking, and are fitted to a mating member. SOLUTION: In the high-hardened stem after soft-nitrided and induction-hardened, the range having a certain depth under the surface is removed for the end surface present in both the ends (the surface to be caulked). Thereby, the end surface to be caulked is reduced in hardness so as to be easy to caulk. COPYRIGHT: (C)2010,JPO&INPIT
摘要翻译：要解决的问题：为了解决通过铆接来适应铆钉的两个端部的问题，如果每个杆都使用仅覆盖的方法进行氮化防止，则需要防止它们被氮化茎头的两端都带有氮化防止剂，处理需要很长时间，所以认为这样做效率不高，而且在不合适的填缝状态下被渗氮的高硬化端部也被接受铆接，并装配到配合构件。解决方案：在软氮化和感应硬化后的高硬化轴中，在两端（待铆接的表面）上存在的端面移除表面下一定深度的范围。因此，要堵塞的端面的硬度降低，容易堵塞。版权所有（C）2010，JPO＆INPIT
