摘要
对基于最大剪切应力为判据的渗碳齿轮硬化层深度设计方法进行了试验验证。结果表明,按照理论硬化层深度进行渗碳热处理得到的硬度分布,在过渡区之后硬度偏低;为了避免齿轮出现深层剥落,可以在理论硬化层深度值上增加一定的层深。
The design method of hardened layer depth of carburized gear based on the maximum shear stress was tested.The results show that the actual hardness obtained by carburizing treatment according to the theoretical depth of hardening layer is found to be low after the transition zone. In order to avoid deep spilling of gears, the actual depth value of hardened layer can be increased appropriately on the basis of theoretical value.
