摘　　要：齿轮故障可以通过齿轮啮合动力学参数表现出来,齿轮啮合刚度和轮齿啮合力对齿轮系统的故障比较敏感,所以研究齿轮动力学啮合参数是对齿轮系统进行精准故障诊断的基础。基于材料力学原理和能量原理建立了求解齿轮时变啮合刚度的理论模型,近一步建立了具有非等齿宽裂纹的齿轮时变啮合刚度理论模型。通过数值仿真,求解了摇臂齿轮在啮合过程的时变啮合刚度;通过对不同程度裂纹齿轮的刚度计算,得出随着裂纹的扩展,齿轮的刚度随着变小的结论。For gear fault can be demonstrated by gear meshing kinetic parameters, particularly, gear meshing stiffness and strength are sensitive to gear fault, analysis of gear meshing kinetic parameters is the basis of gear accurate fault diagnosis. Established a mathematic model of solving gear time-varying mesh stiffness based on materials mechanics and energy principles, afterwards, proposed a mathematic model of solving gear time-varying meshing stiffness with crack propagating along tooth width and crack depth. Time-varying mesh stiffness during gear operating process was solved by numerical simulation. Through simulating gear mesh stiffness of a gear with different crack length and depth, the conclusion that gear mesh stiffness reduced with the crack extended.
