标准摘要
[中文适用范围]： 本文件的目的是通过应用油润滑流体动压滑动轴承的计算方法来实现运行可靠的滑动轴承的设计，其中止推环和滑动轴承表面通过润滑剂膜完全分离[1 ]。 本文件适用于带有集成楔块和支撑表面的滑动推力轴承，该支撑表面具有任意楔块表面长度 lwed 与一个轴瓦长度 L 的比率。 它涉及值 lwed/L = 0,75，因为该值代表最佳比率[2] 。 一个瓦块的宽度与长度之比可以在 B/L = 0.5 至 2 的范围内变化。 本文件中描述的计算方法可用于其他组合间隙形状，例如带有集成隔板的滑动推力轴承，当对于这些类型，雷诺方程的数值解是已知的。 该计算方法用于设计和优化例如用于风扇、齿轮装置、泵、涡轮机、电机、压缩机和机床的滑动推力轴承。 它仅限于稳态条件，即在连续工作条件下所有旋转部件的载荷和角速度恒定。 不包括动态操作条件。 [外文原描述]： The aim of this document is to achieve designs of plain bearings that are reliable in operation, by the application of a calculation method for oil-lubricated hydrodynamic plain bearings with complete separation of the thrust collar and plain bearing surfaces by a film of lubricant [ 1 ] . This document applies to plain thrust bearings with incorporated wedge and supporting surfaces having any ratio of wedge surface length l wed to length of one pad L . It deals with the value l wed/ L = 0,75 as this value represents the optimum ratio [ 2 ] . The ratio of width to length of one pad can be varied in the range B / L = 0,5 to 2. The calculation method described in this document can be used for other incorporated gap shapes, e.g. plain thrust bearings with integrated baffle, when for these types the numerical solutions of Reynolds equation are known. The calculation method serves for designing and optimizing plain thrust bearings e.g. for fans, gear units, pumps, turbines, electrical machines, compressors and machine tools. It is limited to steady-state conditions, i.e. load and angular speed of all rotating parts are constant under continuous operating conditions. Dynamic operating conditions are not included.
