为准确建立斜齿轮动力学模型，更好分析斜齿轮系统振动特性，提出基于轮齿承载接触分析、考虑齿轮轴扭转变形的轮齿啮合刚度计算方法。分析国内文献普遍采用的基于啮合刚度分解建立斜齿轮动力学模型，指出其与理论力学相悖之处，提出基于力、振动位移分解法建立综合考虑时变啮合刚度激励、啮入冲击激励的斜齿轮啮合型弯-扭-轴耦合振动模型。以某斜齿轮副为例进行的仿真计算结果表明，基于承载接触分析的轮齿啮合刚度计算方法能准确、方便求得轮齿啮合刚度，文献[8]动力学响应结果与理论实际存在明显差别，而基于力、振动位移分解法的响应则能与理论实际较好吻合。

In order to establish of dynamic model an accurate of helical gear, and investigate vibration characteristics of helical gear system,a meshing stiffness calculation method was put forward based on the analysis of teeth contact under load and the consideration of shaft torsional deformation.The dynamics models of helical gear built according to the decomposition of meshing stiffness in major domestic literatures,were inspected and some violation against theoretical mechanics was pointed out.Resolving forces and vibration displacements,a helical gear vibration model was established considering the meshing stiffness excitation and the corner mesh impact excitation.Taking some helical gear transmission system as an example,the results indicate that the method based on the analysisi of teeth contact under load can easily and accurately calculate the teeth meshing stiffness.The dynamic responses calculated in a certain literature are significantly different from the actual results.The results by the method of resolving forces and vibration displacements are in good agreement with the theoretical ones.
