摘　　要：为了解决传统的摆线针齿传动输出结构易损坏、结构复杂等问题,将内、外摆线齿廓运用到NN型少齿差行星齿轮传动领域,提出了一种新型的摆线针排齿轮,并进行了其齿廓特性和啮合特性分析。对摆线轮的齿廓方程、压力角进行公式推导,分析了齿廓参数对压力角的影响,为该新型传动系统的应用奠定基础;对不同齿廓修形方法下的内外摆线齿轮进行参数方程推导,并利用Matlab软件进行仿真分析,以解决由于润滑黏膜、制造误差等一系列原因所产生的啮合间隙问题;最后,对双摆线针齿传动进行力学特性分析,为后续的减速器设计和有限元分析提供了理论基础。研究对开发新的传动方式具有意义和工程使用价值。In order to solve the problems of the traditional output structure of the cycloid pinion transmission,such as easy damage and complex structure,a new type of cycloid pinion gear is proposed by applying the internal and external cycloid tooth profile to the field of NN-type less differential planetary gear transmission,and the analysis of its tooth profile characteristics and meshing characteristics is carried out.The equations of the tooth profile equation and pressure angle of the cycloid are derived,and the influence of the tooth profile parameters on the pressure angle is analyzed to lay the foundation for the application of this new transmission system.The parameter equations of the inner and outer cycloid gears under different tooth profile modification methods are derived,and the simulation analysis is carried out using Matlab software to solve the meshing gap problem due to a series of reasons such as lubrication mucosa and manufacturing errors.Finally,the mechanical characteristics of the double cycloid needle gear transmission are analyzed,which provides a theoretical basis for the subsequent design of the reducer and finite element analysis.This study has significance and engineering use value for the development of new transmission methods.
