摘　　要：为了创建偏曲轴少齿差行星减速器内齿轮副的变参装配模型,分析了内齿轮副渐开线任一点的包角与压力角及展角的关系。引进UG的内部参数t,建立了齿顶圆与齿根圆之间的渐开线直角坐标方程,并分别建立了外齿轮与内齿轮渐开线基本表达式。以此为契机,分别进行了内外齿轮及齿轮副装配的参数建模。结果表明,该装配模型在满足一定条件下,随着齿轮的参数变化而变化,为今后对该机构优化设计、运动仿真打下坚实的基础。In order to create the assembly modeling of internal gear pairs of planetary gear reducer of less tooth difference with biasing crankshaft on variable parameters, the relationships were analyzed among the wrap angle, the pressure angle and the turning angle at any point on the involute curve of the internal gear pairs, the inside parameter t in UG was introduced, the equations of rectangular coordinates of the involute curve between the addendum circle and the dedendum circle were built, the parametric models of the external and internal gears were built, at the same time, the assembly modeling of the internal gear pairs was created. The result shows that the assembly modeling changes with the parameters of internal gear pairs under some conditions, and builds a steady basis for the optimizing design and motion simulation of the mechanism in the future.
