It was stated in the previous report that the viscosity of lubricants and the pitch-line velocity of the gears remarkably affect the endurance limit of the pitting. These facts indicate the importance of the lubrication for the pitting. In this report, the experimental studies of the lubricating oil film are presented. The film thickness was obtained by measuring the electrostatic capacity between two rolling rollers. Comparing the measured film thickness with the conventional theoretical values of two kinds, the one obtained by assuming the constant viscosity of lubricant and the other by taking into account the changes of the viscosity under the pressure, it was found that the measured film thickness did not coincide with the theoretical values precisely. So, for the further theoretical analysis of lubricating film, the temperature of the oil film and the elastic deformation of rollers should be taken into consideration.
