标准范围

ISO/TS 16281:2008包含了计算修改参考额定寿命的建议，其中考虑了轴承材料的润滑、污染和疲劳载荷极限，以及倾斜或错位、轴承的工作间隙和滚动元件上的内部载荷分布。ISO/TS 16281:2008中提供的计算方法涵盖了ISO 281中所述参数之外的影响参数。ISO 281中给出的说明和限制适用于ISO/TS 16281:2008.计算方法与轴承的疲劳寿命有关。其他失效机制，如磨损或微剥落（灰色染色），不在ISO/TS 16281:2008的范围内。ISO/TS 16281:2008适用于承受径向和轴向载荷并考虑径向间隙和倾斜的倾斜单列径向滚珠轴承。它也适用于倾斜单列滚柱轴承，承受纯径向载荷，并考虑径向间隙、边缘应力和倾斜。为一般荷载下的内部荷载分布分析方法提供了参考。可根据ISO/TS 16281:2008中给出的方程式，对多列轴承或几何形状更复杂的轴承的内部载荷分布和修正参考额定寿命进行分析。对于这些轴承，必须考虑每行的载荷分布。ISO/TS 16281:2008主要用于计算机程序，与ISO 281一起涵盖了寿命计算所需的信息。为了在上述规定的工作条件下进行准确的寿命计算，建议使用ISO/TS 16281:2008或轴承制造商提供的高级计算机计算，以确定不同载荷条件下的动态等效参考载荷。

ISO/TS 16281:2008 contains recommendations for the calculation of the modified reference rating life taking into consideration lubrication, contamination and fatigue load limit of the bearing material, as well as tilting or misalignment, operating clearance of the bearing and internal load distribution on rolling elements. The calculation method provided in ISO/TS 16281:2008 covers influencing parameters additional to those described in ISO 281.The directions and limitations given in ISO 281 apply to ISO/TS 16281:2008. The calculation methods pertain to the fatigue life of the bearings. Other mechanisms of failure, like wear or microspalling (gray staining), lie outside the scope of ISO/TS 16281:2008.ISO/TS 16281:2008 applies to tilted single-row radial ball bearings, subjected to radial and axial load, and with radial clearance and tilt taken into account. It also applies to tilted single-row roller bearings, subjected to pure radial load and with radial clearance, edge stress and tilt taken into account. References to methods for the analysis of the internal load distribution under general load are given.The analysis of internal load distribution and modified reference rating life for multi-row bearings or bearings of a more complex geometry can be derived from the equations given in ISO/TS 16281:2008. For these bearings, the load distribution for each individual row has to be considered.ISO/TS 16281:2008 is primarily intended to be used for computer programs and together with ISO 281 covers the information needed for life calculations. For accurate life calculations under the operating conditions specified above, it is recommended that either ISO/TS 16281:2008 or advanced computer calculations provided by bearing manufacturers, for determining the dynamic equivalent reference load under different loading conditions, be used.
