标准范围

本文件规定了油润滑流体动力滑动轴承的计算方法，推力环和可倾瓦推力轴承表面通过润滑剂膜完全分离。本文件适用于带有倾斜式滑块（可倾瓦）的推力滑动轴承，其中在运行过程中自动形成楔形润滑间隙。一个焊盘的宽长比可以在B/L范围内变化？=？0.5至2。本文件不适用于重载可倾瓦推力轴承。笔记？存在等效的计算程序，使得能够估计操作条件并根据可接受的条件进行检查。它们的使用同样是可以接受的。

This document specifies a calculation method for oil-lubricated hydrodynamic plain bearings with complete separation of the thrust collar and tilting pad thrust bearing surfaces by a film of lubricant.This document applies to plain thrust bearings with tilting-type sliding blocks (tilting pads), where a wedge-shaped lubrication clearance gap is automatically formed during operation. The ratio of width to length of one pad can be varied in the range B/L = 0,5 to 2.This document is not applicable to heavily loaded tilting pad thrust bearings.NOTE       Equivalent calculation procedures exist that enable operating conditions to be estimated and checked against acceptable conditions. The use of them is equally admissible.
