摘要

将二阶对数修形量沿法线方向叠加至RV减速器摆线轮的理论齿廓,推导出对数修形后的摆线轮齿廓方程。通过控制齿廓修形底数、齿廓修形系数,可达到控制齿廓曲线不同位置的修形量。提出的二阶对数齿廓修形方法与传统修形方法的不同点是:摆线轮主要参与啮合工作段齿廓更加逼近理论齿廓;二阶对数齿廓修形可使摆线针轮副重合度更大,传动误差曲线对称性更好,使摆线轮传动更加平稳。该修形方法具有优越性,为高精度RV减速器摆线轮的修形设计提供了新思路。

Abstract

The second-order logarithmic superposition of modification quantity along the normal direction to the theory of conjugate tooth profile of cycloid gear of RV reducer is carried out,the cycloid tooth profile equation after the modification is deduced. By controlling the base number of the tooth profile modification and the coefficient of the tooth profile modification,the modification quantity control of the tooth profile curve at different position can be achieved. The difference between the second-order logarithmic profile modification method and the traditional parabola method is that the cycloidal wheel mainly involved in the tooth profile of the meshing working section is more closely to the theoretical tooth profile. The contact ratio of second-order logarithmic tooth profile modification is bigger,the transmission error curve has better symmetry,and the cycloidal wheel drive is more stable. This modification method has the advantages,a new way of thinking for the modification design of high precision RV reducer cycloid gear is provided.
