相互接触的机器零件,如轴承、齿轮和凸轮其磨损很大程度上取决于在这些零件上的润滑油膜的厚度。如果油膜厚度太薄,零件会很快磨损,并过早损坏。但以前的一些计算最小油膜厚度的公式都不太可靠,而现根据物体呈椭圆接触的情况,对其在等温下弹性流体动力润滑进行的研究得出了更为 The wear of the parts of the machine that come into contact with each other, such as bearings, gears and cams, depends very much on the thickness of the lubricant film on these parts. If the film thickness is too thin, the parts wear out quickly and prematurely. However, some of the previous formulas for calculating the minimum oil film thickness are not very reliable. However, based on the elliptical contact of the object, the study on its isothermal elastohydrodynamic lubrication is more
