【Abstract】 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.更多还原
