ISO 12131这一部分的目的是通过以下方式实现运行可靠的滑动轴承设计:完全分离油润滑流体动力滑动轴承计算方法的应用止推环和滑动轴承表面由一层润滑剂[1]。ISO 12131的这一部分适用于带有内置楔块和支撑表面的推力滑动轴承楔形表面长度lwed与一个垫L的长度的任何比率。它将值lwed/L=0,75作为该值处理表示最佳比率[2]。一个垫的宽度与长度的比率可以在B/L=0.5至2的范围内变化。ISO 12131这一部分中描述的计算方法可用于其他结合的间隙形状，例如。带整体挡板的推力滑动轴承，当这些类型的雷诺微分的数值解方程是已知的。该计算方法用于设计和优化推力滑动轴承，涡轮机、电机、压缩机和机床。它仅限于稳态条件，即负载和在连续运行条件下，所有旋转部件的角速度都是恒定的。动态操作条件不包括在内。

The aim of this part of ISO 12131 is to achieve designs of plain bearings that are reliable in operation, by theapplication of a calculation method for oil-lubricated hydrodynamic plain bearings with complete separation of thethrust collar and plain bearing surfaces by a film of lubricant [1].This part of ISO 12131 applies to plain thrust bearings with incorporated wedge and supporting surfaces havingany ratio of wedge surface length lwed to length of one pad L. It deals with the value lwed/L = 0,75 as this valuerepresents 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 part of ISO 12131 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' differentialequation 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 andangular speed of all rotating parts are constant under continuous operating conditions. Dynamic operatingconditions are not included.
