摘　　要：针对直线共轭液压泵齿轮齿廓啮合参数缺乏统一系统分析的问题,提出了使用几何方法分析啮合参数的方式。基于Willis定理建立了啮合几何模型,结合各啮合参数定义,使用Solid Works软件参数化功能并结合Excel软件,以范例形式分析和计算啮合角、压力角、滑动系数的啮合参数,揭示了直线共轭齿轮齿廓啮合规律。结果表明使用几何方法分析齿廓啮合参数具有简洁准确、高效等优点,为直线共轭齿轮齿廓设计提供参考。In view of the lack of unified system analysis of gear profile meshing parameters of the straight conjugate hydraulic pump,a geometric method is proposed to analyze the meshing parameters.The meshing geometric model is established based on Willis theorem.Combined with the definition of meshing parameters,the meshing parameters of meshing angle,pressure angle and sliding coefficient are analyzed and calculated in the form of examples by using the parameterization function of SolidWorks software and Excel software,and the meshing law of straight conjugate gear profile is revealed.The results show that using geometric method to analyze the meshing parameters of tooth profile has the advantages of simplicity,accuracy and efficiency,which provides a reference for the tooth profile design of straight conjugate gear.
