本文件根据计算选定的多瓣和可倾瓦轴颈轴承的指导值建立了允许的操作参数。为了通过根据ISO/TS 31657-1的计算获得多瓣和可倾瓦轴颈轴承的足够的操作安全性，操作特征值hmin必须显著高于允许的操作参数hlim、tr，并且允许的操作参数Tlim和plim不被计算的操作特征值Tmax和pmax超过。指导值代表滑动轴承摩擦学系统中基于几何和技术的操作极限值。它们是经验值，即使在较小的干扰影响下也能实现足够的操作安全性（参见ISO/TS 31657-1).所示的经验值可以针对特殊应用领域进行修改。注:符号和计算示例的解释包含在ISO/TS 31657-1中。

This document establishes the permissible operational parameters in terms of guide values for the calculation of selected multi-lobed and tilting-pad journal bearings.In order to attain a sufficient operational safety of multi-lobed and tilting-pad journal bearings by the calculation according to ISO/TS 31657-1, it is necessary for the operational characteristic value h_min to be significantly above the permissible operating parameter h_lim,tr and for the permissible operating parameters T_lim and p_lim not to be exceeded by the calculated operational characteristic values T_max and p_max.The guide values represent geometrically and technologically founded operational limiting values in the tribological system of plain bearings.They are empirical values that enable sufficient operational safety even in the event of smaller disturbing influences (see ISO/TS 31657-1). The empirical values indicated can be modified for special application areas.NOTE The explanations for the symbols and calculation examples are contained in ISO/TS 31657-1.
