摘要
比较了标准ISO 281:1990(我国等同采用为GB/T 6391-2003)与ISO 281:2007(我国等同采用为GB/T6391-2010)关于滚动轴承寿命计算方法的差异,分析了两种标准的修正系数在含义和取值上的差异,以及修正系数对滚动轴承寿命计算结果的影响。研究结果表明,ISO 281:2007引入综合修正系数,该系数综合考虑了ISO 281:1990的材料、润滑两修正系数,此外还考虑到润滑剂中的杂质因素和轴承的疲劳载荷极限,影响因素综合程度高,计算更可靠。
Comparative analysis of International Standards Organization standard （ISO） 281 ： 1990 （ the equivalent of GB/ T6391-2003） and ISO 281：2007 （the equivalent of GB/T6391 -2010 ） Calculation Method for Rolling Bearing Life was conducted. Differences between the meaning and selection of Life modification factor, as well as their effects on Rolling Bearing Life, were analyzed through calculations. The study indicates that the ISO 281：2007 introduces the Life modification factor for systems approach, and the factor considers not only the two factors of the ISO 281 ： 1990 but also the fatigue stress limit of the bearing steel and the contamination in lubricant, which makes it easy and more reliable to estimate the influence of lubrication and contamination on bearing life.
