摘　　要：为了满足齿轮变传动比运动、提高轮齿承载能力,结合齿轮啮合理论和双圆弧齿廓曲线结构参数特征,提出了一种新型双圆弧齿廓椭圆齿轮。阐述了其节曲线的设计方法,利用SolidWorks软件建立了双圆弧齿廓椭圆齿轮三维模型;使用Adams软件对双圆弧齿廓椭圆齿轮副模型进行了运动学仿真,分析了不同偏心率对双圆弧椭圆齿轮副传动比变化规律的影响,并对比理论传动比曲线,分析了仿真传动比曲线存在波动误差的影响因素;为了减小齿轮副振动脉冲,给出了偏心率适当的取值范围。本文的设计方法和分析结果对双圆弧齿廓非圆齿轮的参数化设计有理论参考价值,可为双圆弧齿廓椭圆齿轮副数控加工制造及应用提供依据。In order to meet the requirements of variable transmission ratios and improve the bearing capac⁃ity of gear teeth,a new type of double-circular-arc tooth profile elliptical gear is proposed based on the meshing theory and the structural parameter characteristics of the double-circular-arc tooth circular profile curve.The design method of its pitch curve is described.A three-dimensional model of the double-circular-arc tooth circu⁃lar profile elliptical gear is established using SolidWorks software.Adams software is used to simulate the kine⁃matics of the elliptical gear pair model with double-circular-arc tooth profiles,and the influence of different ec⁃centricities on the variation rule of the double-circular-arc gear pair transmission ratio is analyzed;compared with the theoretical transmission ratio curve,the influencing factors of the fluctuation error of the simulation transmission ratio curve are analyzed.In order to reduce the vibration pulse of the gear pair,the appropriate val⁃ue range of eccentricities is given.The design method and analysis results in this study have theoretical refer⁃ence value for parametric design of non-circular gears with double-circular-arc tooth profiles,and can provide a basis for NC manufacturing and application of elliptic gear pairs with double-circular-arc tooth profiles.
