摘　　要：对数螺旋锥齿轮具有螺旋角处处相等的特点,可以使啮合传动更加平稳,噪声更小,承载能力更强,使用寿命更长。应用Pro/E三维机械设计软件,根据对数螺旋锥齿轮的形成原理,以球面渐开线为齿轮齿廓曲线,以对数螺旋线为锥齿轮齿形线,基于形状结构特征,建立对数螺旋锥齿轮的三维参数化精确模型,进而为后续的产品优化设计、有限元分析及制造奠定基础。The logarithmic spiral bevel gears have the characteristics of equal helical angle,which can make the meshing transmission more stable,less noise,greater carrying capacity and longer service life.According to the forming principle of logarithmic spiral bevel gears,using Pro/E 3D mechanical design software,taking spherical involute as gear profile curve,and taking logarithmic helix as bevel gear profile,and then based on shape and structure characteristics,a 3D parametric accurate model of logarithmic spiral bevel gears was established.Then it laid a foundation for the following product optimization design,finite element analysis and manufacturing.
