滚动轴承.通用负载滚动轴承有效静态安全性的计算方法

[中文适用范围]： 本文件规定了考虑倾角或对齐误差、轴承操作间隙和滚动体内部载荷分布的情况下有效静安全系数的计算方法。 该计算方法涵盖除ISO 76中描述的影响参数外的其他影响参数。 ISO 76和ISO 20056-2中给出的方向和限制适用于本文件。 该计算方法适用于单列和多列的向心球轴承、滚子轴承，这些轴承承受径向载荷和轴向载荷，并考虑了径向间隙和倾角。 分析有效静安全系数的方法可以从此公式推导出来。 [外文原描述]： This document specifies the calculation of the effective static safety factor under consideration of tilt or misalignment, operating clearance of the bearing, and internal load distribution on rolling elements. The calculation method provided in this document covers influencing parameters in addition to those described in ISO 76. The directions and limitations given in ISO 76 and ISO 20056-2 apply to this document. The calculation method pertains to the static safety factor of the bearings. Other mechanisms of failure, like false brinelling, fatigue life, wear or microspalling (gray-staining), lie outside the scope of this document. This document applies to single and multi-row radial and thrust ball and roller bearings, subjected to radial and axial load and with radial clearance and tilt taken into account. References to methods for the analysis of the internal load distribution under general load are given. The analysis of effective static safety factor for multi-row bearings or bearings of a more complex geometry can be derived from the formulae given in this document. For these bearings, the load distribution for each individual row is considered. The calculation of effective static safety factor is also applicable to hybrid bearings, using the static load ratings according to ISO 20056-2.
