The quantitative solutions presented in this chapter are useful for number of reasons. First, they are given in an analytical form with all the inherent advantages over numerical results, of which the bulk of exact solutions exist. Oftentimes they are the only available solutions, a useful guide to how a bearing would possibly perform under certain conditions, and they do provide upper or lower limits. Although the quantitative answers are often at variance with experimental results,they do nevertheless provide means of studying trends and relations.
The presented solution for the dynamically loaded journal bearing yields regions of high negatve pressures.Such negative pressures are rarely encountered in real bearings.Mineral oils contain between8 and12 percent dissolved air.This air will start to come out of solution whenever the pressure falls below the saturation pressure,which reduces the capability of the journal bearings to support high dynamic loads.This

定量解答提出了在这个章节里是有用的为原因的数字。首先, 他们被给以分析形式以所有固有好处数字结果, 大多数确切的解答存在。他们经常是唯一的可利用的解答, 一本有用的指南对于怎样轴承可能会执行在某些情况下,并且他们提供上部或低限。虽然定量答复经常是与实验性结果不一致, 他们然而提供学习趋向和联系手段。
被提出的解答为高阴电子的动态地被装载的学报轴承出产量地区消极压力很少遇到在真正粗暴的.矿物油里的密封,这种包含在8之间到12 百分之被溶化的空气. 这个空气将开始从解答出来每当压力下跌在饱和压力之下, 使学报轴承降低的能力到支持高的动态装载.这就导致了建议消极压力预言由分析应该被忽略。在长的动态地被装载的学报轴承情况下, 唯一的模型可利用是模型由过多提出, 他集成压力等式为动态地装载只在正面压力地区由设置压力在残余的部份相等与它将被回顾和将被评估在下个章节的零度.因为这个模型是重要。
