摘　　要：为探究柔轮齿形修形对谐波减速器啮合性能的作用,建立了中空型谐波减速器的装配模型,采用有限元法分析了柔轮与刚轮啮合情况。以双圆弧齿形的在空载、负载过程中等效变形与等效应力作为对比条件。综合考虑柔轮齿形齿顶修形量,同时调整柔轮齿形轴向的齿高倾角,计算同等边界条件下齿形修形后的等效变形应力情况。对比结果表明,空载与负载条件下,提取柔轮轮齿前缘与后缘的中性层曲线,柔轮的等效变形基本不变,但最大等效应力分别降低至80%与76.6%,啮合性能得到提升。相关研究为谐波减速器的设计、评估及传动性能优化提供有益尝试和参考依据。To explore the effect of the tooth profile modification of the flexible gear on the meshing performance of the harmonic reducer,an assembly model of the hollow harmonic reducer was established,and the meshing situation of the flexible gear and the rigid gear was analyzed by the finite element method.The equivalent deformation and equivalent stress of the double-arc tooth profile in the no-load and load process are used as the comparison conditions.Comprehensively consider the amount of flexible gear tooth profile tooth tip modification,and adjust the tooth height inclination of the flexible gear tooth profile axis at the same time,and calculate the equivalent deformation stress after the tooth profile modification under the same boundary conditions.The comparison results show that the neutral layer curves of the front and rear edges of the flexible gear tooth are extracted under no-load and load conditions.The equivalent deformation of the flexible gear is basically unchanged,but the maximum equivalent stress is reduced to 80%and 76.6%respectively,and the meshing performance is improved.Related researches provide useful attempts and references for the design,evaluation and transmission performance optimization of harmonic reducers.
