Up to the present, the maximum pressure between two rolling rollers has been calculated by hydrodynamic theory on the assumption that the rollers are rigid bodies, or using a method devised by Hertz which ignored the oil film. But these two methods are the extreme cases and unresonable points arise in general case. In this report, a hydrodynamic lubrication theory between two rollers, taking into account the elastic deformations of the rollers, is presented. It was difficult to obtain analytical solutions of the equations, so the author used a digital computer to obtain numerical solutions. As a result, it was shown that under a light load the hydrodynamic pressure calculated by this theory was very close to that calculated by the hydrodynamic theory neglecting deformation, and that under the heavy load the pressure calculated by this theory approached the Hertzian elastic stress. The maximum pressure calculated by this theory was lower than the one calculated by either of the two classical theories.
