Theoretical Analysis of the Lubricating Oil Film between Two Rolling Rollers

In this report, first, the temperature rise of oil film is analysed. In this case, the heat transmission through the surface to the rollers together with heat generation by internal friction loss in the oil film is taken into consideration. Next, the effects of the elastic deformation of rolling surfaces are analysed, and approximate calculating formulas for the maximum pressure on the rolling surface and the minimum film thickness are investigated. Further, the measured film thickness is compared with the value given by the above theory. It is shown that the measured values are involved in the region where the effect of elastic deformation is negligible ; and, when the rolling velocity is high, the measured values are smaller than the values obtained by the theory assuming constant viscosity, but, when the rolling velocity is low, the relation is reversed. This is explained reasonably by the above theory.
