摘　　要：根据空间齿轮啮合原理,提出一种偏心-高阶椭圆锥齿轮副的设计方法,建立了偏心-高阶椭圆锥齿轮副的数学传动模型,推导出偏心椭圆锥齿轮和与其相互啮合的高阶椭圆锥齿轮的节锥面、球面节曲线方程;分析了范成法生成偏心-高阶椭圆锥齿轮齿廓的过程,获得了范成刀具的空间走刀位置;结合VB与Solidworks(API),开发出偏心-高阶椭圆锥齿轮仿真加工设计程序,得到了偏心-高阶椭圆锥齿轮副的虚拟实体及其装配模型;通过对偏心-高阶椭圆锥齿轮副传动特性的分析,得到了偏心-高阶椭圆锥齿轮副传动过程中传动比、从动轮角速度和角加速度的变化规律。Base on the space engagement theory,a design method of eccentric-high order elliptical bevel gear pair was presented,the mathematical model of eccentric-high order elliptical bevel gear drive was established,pitch cone and spherical pitch curve of the eccentric elliptical bevel gear and the high order elliptical bevel gear were derived;the position of the cutter in the space during tooth profile of eccentric-high order elliptical bevel gear was generated analyzed.Secondary development based on Solidworks（API） and VB,which made the pseudo-entity and assembly model of eccentric-high order elliptical bevel gear pair was obtained;and then the transmission characteristics of eccentric-high order elliptical bevel gear pair was analyzed,the change laws of eccentric-high order elliptical bevel gear pair,angular velocity and angular acceleration of driven wheel during the transmission were acquired.
