摘　　要：在研究分析了轮齿间油膜的动力学性能的基础上 ,提出了把此油膜看成是一个质量 -弹簧 -阻尼系统的假设 ,并运用弹流理论 ,分析了油膜厚度和油膜等效刚度 ,建立了相应的动力学模型和运动微分方程 ,对运动微分方程进行了计算和分析 。On the basis of researching and analyzing the dynamic properties of oil film lying between teeth of gears, this paper put forward an assumption of regarding this oil film as a mass-spring-damping system. By utilizing the theory of elastohydrodynamics the thickness and equivalent stiffness of oil fiml are being analyzed and th corresponding dynamic model and kinematic differential equations are established. Calculations and analysis are carried out on the kinematic differential equations and finally the difference of dynamic response is being compared on geared dynamic systems with or without the oil film.
