摘　　要：斜齿微线段齿轮是一种新型齿轮 ,它具有最小齿数少等众多的优点。该文介绍了斜齿微线段齿轮的基本特性 ,在分析现有各种齿轮胶合承载能力的计算方法的基础上 ,结合斜齿微线段齿轮的传动特点 ,基于弹流动力润滑理论建立了其摩擦学系统模型 ;并指出最小油膜厚度法可用于进行斜齿微线段齿轮的胶合计算 ,导出了与之相关的综合曲率半径及卷吸速度的理论计算公式 。The common methods of calculating the scuffing strength of gear are introduced first. Then based on the theory of elastohydrodynamic lubrication(EHL) and in light of the transmission characteristics of the micro-segment helical gear,a novel kind of gear the relative curvature of the profile of which being zero at many contact points,the method of minimum oil thickness is advanced to calculate the scuffing strength of the novel gear,and its model of tribologic system is constructed.The formulas for calculating the compositive radius of curvature and the tangential speed are deduced. An application example is given.
