对于硬齿面齿轮的承载能力,仲复欣同志在《论硬齿面齿轮的承载能力》一文(以下简称仲文)的结论中指出:为了保证大曲率半径、大模数重载齿轮的齿面硬化后的承载能力提高,必须有足够的硬化层深度、必要的心部硬度和最小的过渡区残余拉应力。根据不同类型的齿轮,应合理地选择齿轮硬化方法。这一 For the carrying capacity of hardened gears, Comrade Zhong Fuxin pointed out in his article “On the bearing capacity of hardened gears” (hereinafter referred to as Zhongwen): In order to ensure the large radius of curvature, large module heavy gear teeth After the hardening of the bearing capacity increase, there must be sufficient hardened depth, the necessary core hardness and minimum residual tensile stress in the transition zone. Depending on the type of gear, the gear hardening method should be chosen reasonably. This one
