一、引言人们力求在润滑机构内的两个互为压力接触的表面间保持一完整的油膜。人们知道,油膜厚度愈减小,则接触面的形状误差或变形显得愈大,而且油膜的形成和保持的实际条件与以理想表面(例如旋转的圆柱体或完美的几何球面)为准的计算所得条件相差也愈远。然而明确下述一点也是有好处的,即形状误差的存在并不都是坏事,例如象密封垫之类的一些零件,只有靠其变形才能工作。可是事情并不仅如此,形状误差的存在会显著改变轴承的承
I. INTRODUCTION People seek to maintain a complete oil film between two surfaces in pressure contact with each other in the lubrication mechanism. It is known that as the film thickness decreases, the shape error or distortion of the contact surface becomes larger, and the actual conditions for the formation and retention of the film depend on the calculation of a perfect surface (such as a rotating cylinder or a perfect geometric sphere) The conditions for the difference also farther. However, it is also advantageous to note that the existence of shape errors is not always a bad thing. For example, parts such as gaskets work only by deforming them. But things are not the case, the existence of shape errors will significantly change the bearings bearing
