摘　　要：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 70 0 7和 70 1 8润滑脂进行的拖动力测试 ,获得了不同载荷、速度条件下的两种润滑脂的拖动系数与滑滚比之间的关系曲线。通过对试验数据的处理 ,采用适当的数学模型和国际通用的无量纲参数作为表达式 。In this paper, it is involved that traction force tests for high-speed aviation greases No.7007 and No.7018 are performed by using a rig designed by ourselves and the curves of the traction coefficients with the ratio of sliding and rolling are obtained at various loads and speeds. After the data processing for test results, two useful formulas which are described by the world-wide used EHD parameters are advanced to calculate the traction coefficients of No.7007 and No.7018 lubricating grease.
