本文件规定了油润滑流体动压滑动轴承的计算程序，该轴承通过一层润滑剂将轴和轴承滑动面完全分离，用于设计运行可靠的滑动轴承。 它涉及角跨度为360°、180°、150°、120°和90°的圆柱轴承，圆弧段集中加载。除了润滑油膜压力和温度引起的可忽略的变形外，它们的间隙几何形状是恒定的。 计算程序用于提供尺寸并优化涡轮机、发电机、电动机、齿轮装置、轧机、泵和其他机器中的滑动轴承。它仅限于稳态操作，即在连续驱动的操作条件下，负载的大小和方向以及所有旋转部件的角速度恒定。 如果全滑动轴承受到以任何速度旋转的恒力，也可以使用该方法。不考虑动态载荷（即大小和方向随时间变化的载荷），例如快速运行转子的振动效应和不稳定性可能导致的载荷。 注:存在等效计算程序，可以根据可接受的条件估计和检查运行条件。使用它们也是同样可以接受的。

This document specifies a calculation procedure for oil-lubricated hydrodynamic plain bearings, with complete separation of the shaft and bearing sliding surfaces by a film of lubricant, used for designing plain bearings that are reliable in operation. It deals with circular cylindrical bearings having angular spans, Ω, of 360°, 180°, 150°, 120°, and 90°, the arc segment being loaded centrally. Their clearance geometry is constant except for negligible deformations resulting from lubricant film pressure and temperature. The calculation procedure serves to provide dimensions and optimize plain bearings in turbines, generators, electric motors, gear units, rolling mills, pumps, and other machines. It is limited to steady-state operation, i.e. under continuously driven operating conditions, with the magnitude and direction of loading as well as the angular speeds of all rotating parts constant. It can also be applied if a full plain bearing is subjected to a constant force rotating at any speed. Dynamic loadings (i.e. those whose magnitude and direction vary with time), such as those that can result from vibration effects and instabilities of rapid-running rotors, are not taken into account. NOTE Equivalent calculation procedures exist that enable operating conditions to be estimated and checked against acceptable conditions. The use of them is equally admissible.
