弹流拖动特性是润滑剂的重要性能,它对滚动轴承的 动态性能有着很大的影响。阐述了用自行设计的高速润滑脂弹流拖动力试验台在充分供脂条件下对国产7007和7018润滑脂进行的拖动力测试以及试验数据的处理,并提出了可供工程上使用的这两种润滑脂的弹流拖动系数计算公式。

The study on traction behaviors of lubricants which have great influences on dynamic properties of rolling bearings is a vital field of elastohydrodynamic lubrication research. In this paper, a concise description of the traction test pattern, the results of test and data processing of No. 7007 and No. 7018 high speed aviation grease are involved. In the end, two useful formulas are advanced to calculate the traction coefficients of No. 7007 and No. 7018 lubricating grease.
