ISO 12130的目的是通过应用推力环和推力环完全分离的油润滑流体动力滑动轴承的计算方法滑动轴承表面涂有一层润滑剂。ISO 12130的这一部分适用于带有倾斜式滑块（倾斜垫）的推力滑动轴承，其中楔形润滑间隙在运行过程中自动形成。一个衬垫的宽度与长度之比可以在B/L=0.5至2的范围内变化。ISO 12130这一部分中描述的计算方法可用于其他间隙形状，例如抛物线润滑间隙，以及用于其他类型的滑块，例如圆形滑块，当用于这些给出了雷诺微分方程的数值解。ISO 12130-2仅给出平面楔形间隙的特征值；因此，这些值不适用于具有轴向支撑。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。ISO 12130的这一部分不适用于重载可倾瓦推力轴承。

The aim of ISO 12130 is to achieve designs of plain bearings that are reliable in operation by the application of acalculation method for oil-lubricated hydrodynamic plain bearings with complete separation of the thrust collar andplain bearing surfaces by a film of lubricant.This part of ISO 12130 applies to plain thrust bearings with tilting-type sliding blocks (tilting pads), where a wedgeshapedlubrication clearance gap is automatically formed during operation. The ratio of width to length of one padcan be varied in the range B/L = 0,5 to 2.The calculation method described in this part of ISO 12130 can be used for other gap shapes, e.g. paraboliclubrication clearance gaps, as well as for other types of sliding blocks, e.g. circular sliding blocks, when for thesetypes the numerical solutions of Reynolds' differential equation are present. ISO 12130-2 gives only thecharacteristic values for the plane wedge-shaped gap; the values are therefore not applicable to tilting pads withaxial support.The calculation method serves for designing and optimizing plain thrust bearings e.g. for fans, gear units, pumps,turbines, electric 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.This part of ISO 12130 is not applicable to heavily loaded tilting pad thrust bearings.
