英文摘要
The rheological properties of solidified lubricant oils under very high pressure were evaluated by observing plastic deformation of metal microspheres in the oils, occurring due to non-hydrostatic pressure in the pressure chamber and by establishing a new method to evaluate stress state of the solidified oils. Solidification pressures, viscosities and shear stresses of the solidified oils could be estimated up to 6GPa at 100C. The established method and oil rheological data at extremely high pressure, which have not been obtained before, are useful for predicting fatigue life and friction loss of the machine elements such as rolling bearings and variable transmissions.
