摘　　要：运用空间啮合原理求出超环面行星蜗杆机构含误差的啮合方程,求出各误差的影响系数。综合考虑加工成本、尺寸因素、装配性能等工程实际,结合各误差的影响系数,提出了超环面行星蜗杆机构改进最佳极限偏差分配法,对超环面传动关键零件误差进行合理分配,并给出实际算例。以上研究为超环面行星蜗杆机构的精度规范打下基础,将促进超环面行星蜗杆传动机构在工程实际中的推广应用。The equation of meshing with error of toroidal drive and the error-impinged coefficient of each error are derived based on spatial meshing theory. Considering the manufacturing cost, the dimension factor and assembly performance in engineering practice and combining error-impinged coefficient, a method to improve the best limit deviation and tolerance allocation is proposed. Distributing the tolerance of key components in toroidal drive is allocated equitably, and a numerical example is also given. The above studies provide a foundation of precision standard for toroidal drive, and the toroidal drive will be promoted its application to engineering practice.
