本文件规定了在流体润滑状态下，油润滑和静载流体动压滑动轴承的最高轴承温度和润滑油膜中有效动态粘度的计算程序，该轴承具有圆柱形形状，角跨度Ω为360°，宽度比B*为0.5至1.5。轴承特性通过四个无量纲数的设计图获得，这四个无量纲数是根据轴承尺寸、操作条件和润滑剂的粘度特性计算出来的。

This document specifies a calculation procedure for the maximum bearing temperature and effective dynamic viscosity in the lubricant film of oil-lubricated and statically loaded hydrodynamic plain journal bearings with a circular cylindrical shape, angular span Ω of 360° and width ratio B* of 0,5 to 1,5 under fluid lubrication regime. The bearing characteristics are obtained by design charts from four dimensionless numbers which are calculated from bearing dimensions, operating conditions and viscosity characteristics of the lubricant.
