本文从国内各厂家生产的全液压转向器和摆线马达的实际需要出发,根据摆线副的啮合原理及其实际工况确定了以总效率为优化设计的目标函数,以等距修正量、移距修正量为设计变量,推导并验证了摆线副的可装配性条件、搜寻到了摆线副在最佳啮合间隙时的摆线副齿形最佳相对修正量、并对摆线轮进行了有限元分析,采用SAP—5程序计算出了摆线轮轮齿的弹性变形量并将其编入优化电算程序。为摆线副的生产、装配提供了必要的理论基础,为摆线副特征尺寸的公差的制定提供了重要的依据。
Based on the actual needs of hydraulic steering gear and cycloidal motor produced by domestic manufacturers, the objective function with total efficiency as the optimal design is determined according to the meshing principle of cycloidal pair and its actual working conditions, The amount of correction for the displacement is taken as the design variable, the assembly condition of the cycloidal pair is deduced and verified, the best relative correction of the cycloid pair profile is found when the cycloidal pair is in the best meshing clearance, For the finite element analysis, the amount of elastic deformation of the cycloidal gear was calculated using SAP-5 program and programmed into the optimized computer program. It provides the necessary theoretical basis for the production and assembly of the cycloidal pair and provides an important basis for the formulation of the tolerance of the cycloidal secondary feature size.
