摘要

为了进一步研究微齿轮齿面磨损机理,采用经典Archard磨损公式,结合JKR（Johnson K L,Kendall K,Roberts A D）理论与GW（Greenwood and Williamson）表面粗糙模型,首次建立了微齿轮粗糙齿面仿真模型,并提出了减轻微齿轮齿面磨损的方法。进行了考虑表面吸引力、齿面粗糙度、微凸体顶点曲率半径、材料性能等单一因素和齿面粗糙度、微凸体面密度、微凸体顶点曲率半径等多个因素对齿面磨损影响的仿真。结果表明,适当增加齿面粗糙度;增大齿面微凸体顶点曲率半径;选用描述粗糙表面的参数乘积ηβσ值较大的齿轮;增大微齿轮的弹性模量等可以提高微齿轮的耐磨性能。

Abstract

In order to further study the microscopic wear mechanisms of micro gear,by using the classical Archard wear equation,combining with JKR（Johnson K L,Kendall K,Roberts A D） theory and GW（Greenwood and Williamson） rough surface model,a simulation model of the wear in micro gear is firstly established and the measures to reduce tooth wear are proposed.The simulation with considering the influence of single factor and multiple factor of surface attractive forces,surface roughness,the radius of curvature in asperity apex,material property etc.on tooth surface wear is carried out.The results show that an appropriate increasing in the surface roughness,reducing the radius of curvature in asperity apex,selecting the gear with larger parameter product value ηβσ which describing the rough surface,choosing the material which has a larger elastic modulus can alleviate wear and extend wear life.
