摘要: 计算了修形前后摆线齿轮与针齿的啮合作用力,通过初始间隙的分布曲线判定了修形摆线齿轮与针齿的同时啮合齿数。建立了摆线齿轮及针齿的参数化模型,并导入到ANSYS软件当中,建立了以“接触单元密分和非接触单元粗分”为原则的有限元模型,分别对标准齿形摆线齿轮及修形摆线齿轮的啮合作用力进行了有限元接触应力分析,得到了考虑摩擦因数的最大啮合作用力,并与通过理论公式计算出的最大啮合作用力进行对比分析。研究结果可为工程上摆线针轮传动的受力分析提供理论依据和技术支持。

Abstract: The meshing force between pin wheels and cycloidal gears with standard profile and profile modification is calculated.The meshing teeth is judged by distribution curve of initial gap.The parametric model of cycloidal gear and pin wheel is built.The finite element model of the cycloidal gear and pin wheel are built by ANSYS with the principle of segment the contact path.Finite element method is applied to perform tooth contact stress analysis of cycloid reducer including standard cycloid reducer and profile modification cycloid reducer.The maximum meshing force with friction is obtained from finite element analysis.The analysis result is compared to the theoretical computation results,and that would take a reference for the analysis of force on engineering.

Key words: cycloidal drive, contact stress analysis, finite element analysis, meshing force
