第一节中略为说明了多楔式油膜轴承的构造。在本节中拟对油膜的性质作一个最简单的数学分析,并说明油膜轴承的几个基本特性。轴与轴承间的高压油膜是怎样发生的呢?这完全是由於滑油的黏性。一切的液体都具有一定的黏性。所谓黏性者,便是液体对于它本身流动的阻力;换言之,也便是使它以一定速度流动时所需加上的外力。黏性小的液体,譬如水银,只要略受外
The first section slightly shows the multi-wedge oil film bearing structure. In this section, we want to make a simple mathematical analysis of the nature of the oil film and illustrate some of the basic characteristics of the oil film bearing. High-pressure oil film between the shaft and the bearing is what happened? This is entirely due to the viscosity of the oil. All liquids have a certain viscosity. The so-called sticky person, is the liquid on its own flow resistance; in other words, it is also made when it flows at a certain speed plus the required external force. Small viscosity liquid, such as mercury, as long as slightly affected by the outside
