通过对氮化和表面渗碳硬化齿轮大量的试验研究,设法揭示对齿轮进行氮化处理的可能性和局限性。我们能这样说,氮化齿轮的齿根强度和齿侧面的承载能力比渗碳淬火齿轮要差,通过去掉脆性的复合层。齿根强度会有较大程度的提高。我们能得出这样的结论,对承受重载的传动齿轮,采用齿轮氮化处理的范围是极其有限的。必须在对载荷特性作清晰的分析以及考虑这两种热处理方式各自的优点后,才能最后决定选用最适合的方法。 Through a large number of experimental studies on nitriding and surface hardening of carburized gears, attempts have been made to reveal the possibilities and limitations of gear nitriding. We can say that the root strength of gear and gear tooth side of the gear bearing capacity than carburized quenching gear worse, by removing the brittle composite layer. Dental root strength will have a greater degree of improvement. We can conclude that the gear nitriding range is extremely limited for heavily loaded drive gears. Only after a clear analysis of the load characteristics and consideration of the respective advantages of the two heat treatment methods can the final decision be taken to select the most suitable method.
