三、线接触全膜弹流理论线接触是弹流问题中较简单的一种(如直齿轮传动、滚子轴承和凸轮机构等)。因为在进行它的润滑分析时,只需采用一维的雷诺方程;而在作变形分析时,可按平面应变状态来处理。因而,近30年来,人们首先对它进行了大量的研究,并建立了被实践所证实的理论。另外,对线接触弹流研究的结果也反映了弹流问题的共同特点。因此,我们在这里对它给以重点介绍。
Third, the line contact with the whole film Elastic theory Line contact is a simpler type of spring flow problems (such as spur gear transmission, roller bearings and cam institutions, etc.). Because in its lubrication analysis, only one-dimensional Reynolds equation; and in the deformation analysis, the plane strain state can be processed. Therefore, in the recent 30 years, people first conducted a great deal of research on it and established a theory that has been proved by practice. In addition, the results of the research on the line-contact spring-current also reflect the common characteristics of the spring-current problem. Therefore, we give a briefing here.
