概要

In this study, investigation was made on the traction characteristic under wide-ranging mean Hertzian pressure from 0.7GPa to 2.3GPa with using various axial direction curvature steel specimens. And then, same tests were carried out under test conditions for several types of traction oil. As a result, in the case of the synthetic naphthenic traction, oil, it was shown that the maximum traction coefficient increased slowly with the increase of mean Hertzian pressure at the first stage of that traction coefficient curve. After then, that traction coefficient curve gradually decreased. And, the numerical analysis was carried out by the Tevaarwerk's elastoplasticity shearing model with some oil film properties in EHL state reported by another researches.
