摘要
渗碳淬火齿轮的应用日益广泛。为提高齿轮的承载能力,必须使之获得足以抵抗接触疲劳破坏的有效硬化层。可通过分析齿轮失效机制和损伤过程,运用赫兹应力公式、藤田公式及Smith理论,在弹性范围内计算渗碳淬火齿轮的有效硬化层深度,同时提供了计算渗碳淬火齿轮有效硬化层深度的经验公式。
Application of carburized and hardened gears is increasingly popularized. The carburized and hardened gear must be provided with effective case sufficient to resist contact fatigue breakdown to increase the load-bearing capability. On the basis of the analysis on both the failure mechanism and the damage process of gear, the effective case depth of gear carburized and hardened can be calculated in the elastic range using the H Herz formula, Fujita formula and Smith theory. Furthermore, there was a empiric formula to calculate the effect case depth of gear carburized and hardened.
