本文介绍了用有限元法对一对渐开线直齿轮啮合时的扭转刚度进行详细分析的结果。自适应网格已被用于商业有限元程序中，以揭示从单齿到双齿接触区的转换区域中的详细行为，反之亦然。分析过去的齿轮齿刚度模型，包括单齿和多齿模型的个人和组合扭转啮合刚度。齿轮体刚度已被证明是一个主要组成部分的总啮合刚度，并提出了一个修正的方法来预测组合扭转啮合刚度。进一步表明，啮合刚度和载荷分配比将是施加载荷的函数。
Abstract This paper presents the results of a detailed analysis of torsional stiffness of a pair of involute spur gears in mesh using finite element methods. Adaptive meshing has been employed within a commercial finite element program to reveal the detailed behaviour in the change over region from single- to double-tooth contact zones and vice versa. Analysis of past gear tooth stiffness models is presented including single- and multitooth models of the individual and combined torsional mesh stiffness. The gear body stiffness has been shown to be a major component of the total mesh stiffness, and a revised method for predicting the combined torsional mesh stiffness is presented. It is further shown tha the mesh stiffness and load sharing ratios will be a function of applied load.
