关于润滑对齿轮振动影响的理论探讨

Theoretical Analysis of the Affection of Lubrication Oil on Gear Vibration

分析了齿面弹流油膜对轮齿啮合则度的影响，导出了平行圆柱体挤压油液阻尼的理论计算公式，建立了圆柱齿轮副的一个比较完善的振动动力学模型，并论述了齿面弹流油膜对振动微分方程结构的影响。

With the analysis of the in fluence of EHL film on the gear tooth meshing sliffness, a theoretical formula is derived for the damping force of the lubricating fluid between two parallel cylinders and a more perfect dynamic model is established for the vibration of the spur gear pair. The influence of the EHL film on the structure of the differcial vibration equations is also discussed
