摘要
结合ISO 281:2007讨论了黏度比κ通过aISO对轴承额定寿命计算的显著影响,澄清了标准中对黏度比κ两种计算方法适用前提的含糊描述。通过分析计算表明,在滚动接触表面超精研加工和一般运行条件下,黏度比κ应该按照黏度的比值进行计算,否则应该按照油膜参数进行计算。
Combined with IS0 281： 2007, the great influence of viscosity ratio κ on bearing rating life calculation through also is discussed, vague description on the preconditions for the calculation of κ is clarified. Upon calculation and analysis, viscosity ratio κ should be calculated by the ratio of viscosity for super finishing contact surfaces and moderate bearing running speed and load, otherwise, it should be calculated by oil film parameter.
