摘　　要：为了改善正交变传动比面齿轮的传动质量与承载能力,研究了该齿轮副的基本几何参数对其重合度的影响。应用齿轮啮合原理,建立了正交变传动比面齿轮副的传动坐标系,推导出正交变传动比面齿轮副的节曲线及齿顶曲线方程。将正交变传动比面齿轮副传动展开成非圆齿轮齿条的传动形式,提出了点接触正交变传动比面齿轮副重合度的计算方法,分析了刀具齿轮及齿轮副的基本几何参数对其重合度的影响。通过测量试验得到的重合度与理论重合度的对比分析验证了该齿轮副重合度计算方法的正确性。To improve the transmission quality and bearing capacity of orthogonal variable transmission ratio face gear,the influences of the geometric parameters of gear pair on the contact ratio are investigated.According to the spatial gear meshing theory,the meshing coordinate is established and the equations of the section curve and crest curve s are deduced.The orthogonal variable transmission ratio face gear is transformed to non-circular gear rack and pinion.The calculation method of the contact ratio is proposed,and the influences of the geometric parameters of cutter gear and gear pair on the contact ratio are analyzed.The proposed calculation method of the contact ratio is verified by the measurement experiment of the actual contact ratio.
