在本文中，考虑全局轮齿挠度和局部接触挠度，在接触路径的任意点评估正齿轮副的啮合刚度，并通过解析的简单函数进行近似。利用此函数，可以计算负载分配比，并与之前根据最小弹性势能假设（MEPE 模型）获得的结果进行比较，考虑齿形挠度，但忽略赫兹挠度。还对标准和高重合度正齿轮的两个模型的临界弯曲和接触应力进行了比较。
In this paper, the meshing stiffness of spur gear pairs, considering both global tooth deflections and local contact deflections, is evaluated at any point of the path of contact and approximated by an analytical, simple function. With this function, the load sharing ratio is calculated and compared with previous results obtained from the hypothesis of minimum elastic potential energy (MEPE model), considering the tooth deflections, but neglecting the hertzian deflections. Critical bending and contact stresses from both models are also compared both for standard and high contact ratio spur gears.
