< jats: p>本文介绍了一种适用于平行表面，如旋转轴端面密封表面的液体润滑理论。提出的润滑机制是基于表面微观不规则性和相关的膜腔。封闭形式的解析解得到作为速度，粘度和表面粗糙度尺寸的函数的负载能力。理论结果同意定性与负载能力实验确定的三个粗糙分布。
< jats: p> This paper describes a theory of liquid lubrication applicable to parallel surfaces, such as the surfaces of a rotary-shaft face seal. The lubrication mechanism presented is based on surface microirregularities and associated film cavities. Closed-form analytical solutions are obtained giving load capacity as a function of speed, viscosity, and surface-asperity dimensions. The theoretical results agree qualitatively with load capacity determined experimentally for three asperity distributions.
