摘  要:比较了双环减速器的少齿差内啮合齿轮副几何尺寸不同计算公式特点,并阐述其啮合时所要满足的限制条件。在此基础上,研究了变位系数、齿顶高系数、中心距之间的关系,提出了基于Matlab最小啮合角变位系数优化选择方法,并通过实例加以验证,同时研究了不同步长对计算结果影响。结果表明,该方法优化准确性高,可避免其他优化方法缺点。Different formula characteristics of internal gear pair with few teeth difference of novel type double ring reducer are compared, the restricted conditions of them when meshing are set forth. On this basis, the relationships between modification coefficients, tooth addendum coefficient and the center distance are studied, the optimal choice method for modification coefficient based on matlab for the smallest meshing angle is proposed, and it is verified with living example, at the same time the effect of the different step lengths on calculation results is researched. The results show that, the optimum method is accurate, the disadvantages of the other optimal choice methods can be avoided.
