TSXCAY22材料弹性力学使得齿轮组啮合时,主、被动齿轮可简化为围绕轴心线旋转的悬臂梁模型[1]，在承受负荷时会产生弯曲变形, 而且齿面接触区域存在弹性形变。另外，齿轮制造加工误差、壳体加工误差、装配等各种误差的客观影响, 造成齿轮实际啮合点与理论啮合区域存在偏移, 产生了啮合冲击激励。为了减少齿轮啮合时产生的误差,在设计早期应该对齿轮的NVH做仿真预测。齿形修形是优化齿轮接触位置和应力大小的有效方法，微观修形可以针对啮合的一对齿轮，也可只做单齿轮修形优化，在工程实践中通常更多采取对单一齿轮修形，其具备较高的生产效率和较低的生产成本。通常齿廓修形的关键影响因子有轮廓修形、宽度、齿根和齿顶修形，其中齿根修形参数的确定,需要兼顾修形参数的选择同时考虑齿轴的系数，避免齿根修形过大引起齿轮齿根弯曲强度的降低。图4展示了齿廓修形的常规形式，包括左右端直线修形、螺旋线修形和鼓性修形。具体齿廓修形的方案选择，需综合考虑输入负荷激励的大小、传递路径的刚度及易加工等因素，结合NVH仿真工具优选齿廓修形方案。
