摘　　要：为探讨齿面微观几何形貌对齿轮啮合振动特性的影响,基于真实齿面的统计特性,借助分形几何理论以及Herz公式,建立了基于真实齿面微观几何形貌的法向接触阻尼的近似数学模型。在此基础上,对比磨削加工和电化学光整加工所得齿面微观几何轮廓的分形参数,分析了加工方法对齿面法向接触阻尼特性的影响,并进一步研究了齿面法向接触阻尼对齿轮啮合振动特性的影响。结果表明:齿面微观几何形貌影响齿轮的啮合振动;加工方法影响齿面法向接触阻尼的变化率;与磨削加工相比,电化学光整加工齿面的法向接触阻尼更大,可减小齿轮啮合振动,有助于提高振动的稳定性。In order to discuss the influence of microstructure of tooth surface on the vibration of gear engagement,an approximate mathematical model for the normal contact damping of microstructure was built based on the statistical properties of real tooth surface by utilizing the theory of fractal geometry and herz formula.On the basis of this,the analysis about the influence of processing methods on the normal contact damping properties and the further research on the influence of normal contact damping on the vibration of gear engagement were done by comparing the fractal parameters of micro-geometry profile of tooth surfaces gained through grinding process and electrochemical finishing.The results show that the microstructure of tooth surface can affect the vibration of gear engagement;processing methods affects the change rate of normal contact damping of the tooth surface.Compared with grinding process,the tooth surface subject to electrochemical finishing have a greater normal contact damping,it can reduce the vibration of gear engagement,thus improving the vibration stability.
