Traction curves are fundamental data for the design of traction-type continuously variable transmission (tCVT) of automobiles, in which maximum hertzian contact pressure exceeds 3 GPa. Under such high contact pressure, oils seems to behave like solid lubricants and elastic contact mechanics (creep theory) seems to be appropriate for evaluation of traction curves similar to that of railway wheels. In the present study, oil-solidified high-pressure traction curves with spin were roughly and simply calculated up to 3 GPa based on creep theory together with maximum traction coefficients of pure roll experimental data of reference. Calculated curves were almost consistent with several reference experimental ones of various conditions (speed, geometry of test machine). This consistency proved that main factor of oil-solidified high-pressure traction curves with spin is creep theory and main rheological property of oils is the limiting shear stress.
