The author has reported by the 3rd report that the viscosity of lubricants and the peripheral speed of the gears remarkably affect the endurance limit of the pitting. Then, the theoretical analysis for hydrodynamic film lubrication is presented in the present report, in which the temperature rise of the oil film and the heat transmission through the surface to the rollers together with the internal friction loss in the oil film are taken into consideration. Further, the measured film thickness, reported in the 4th report, is compared with the above theory on the assumption that the rollers are rigid bodies. It is shown that, with the aid of the above theoretical analysis, the experimental results are explained reasonablly.
