为了研究油膜轴承油的黏温特性，采用NDJ-5 S数显旋转黏度计测定S220、M220和H460三种油膜轴承油在常压、20～90℃温度范围的黏度值，得到不同黏度等级油膜轴承油的黏温曲线，并采用幂关系式和指数关系式对黏-温曲线进行拟合，得到三种油膜轴承油的黏温公式。分析比较拟合结果表明，在20～90℃温度范围内以幂关系作为油膜轴承油的黏温公式更符合实际情况。

In order to study the viscosity-temperature characteristic of lubricating oils used in oil film bearing,the NDJ-5 S digital viscometer was used to measure the viscosity of S220 oil,M220 oil,and H460 oil under normal pressure and the temperature ranging from 20 ℃ to 100 ℃.The viscosity-temperature curves of the three oils were got,and the viscosity-temperature formulae were obtained by fitting the viscosity-temperature curves with power relationship and exponential rela-tionship.It is shown through analyzing the fitting results that the power relationship as the viscosity temperature formula of the lubricating of oil film bearing is more consistent with the actual situation.
