Abstract
In order to grasp main factor of oil-solidified high-pressure spin traction curves, rough and simple calculations based on creep theory were reported compared with reference experimental data up to 2 GPa mean Hertzian pressure. The calculations were also based on the pure rolling experimental data, whose experiments had been already reported to almost agree with the calculation by creep theory. The important property in solidified oil for traction analysis was only the limiting shear stress (Shear strength). Experimental spin traction curves of references were almost expressed by the calculated curves for all spin angles. In the creep theory, apparent slide is induced from surface displacement in contact area by elastic shearing of rotating rollers and is independent of oil film thickness (velocity).
