环隙科特层流润滑理论

根据环隙科特流理论导出了滑动轴承偏心环隙的单位宽循环流量公式 .在以空气为介质的实验中 ,证实了Sommerfeld边界条件 ,即在最大间隙和最小间隙处的压强等于环境压强 .并分别对无限长轴承与有限长轴承建立了断面流量与坐标之间的关系 ,揭示出了这种偏心轴承可能产生的极限承载能力和最小承载能力 .并第一次提出了在最大压强、最小压强处的坐标和通过该断面的流量与相对偏心量有函数关系的观点 ,以及有限长轴承中界面上的压强分布与无限长轴承压强分布成比例 .

The Lubrication Theory of the Couette Laminar Flow Between Two Concentric Cylinders

The paper derives the unit discharge formula of a journal sliding bearing according to the theory of Couette flow between two concentric cylinders. Through experiments using air as media, the paper confirms the Sommerfield boundary conditions. That is the pressure in both maximum and minimum gap is equal to the surrounding pressure. Furthermore, the paper establishes the specific relation between sectional flux and coordinate pertaining respectively to bearings of infinite length and bearings of limited length. It opens out the possible maximum and minimum bearing capacities of the kind of eccentric bearings. For the first time, the paper puts forward the viewpoint that coordinates at the point of maximum pressure and minimum pressure, as well as the flux passing the section have functional relations with the relative eccentricity,and the pressure distribution is similarity between bearings of infinite length and bearings of limited length.
