For the purpose of finding radical preventive measures for the wear and damage of the geartooth surface, the present study was carried out. This paper describes some experiments with roller testing apparatus with which the frictional moment and the electrical resistance between the rollers were measured under various driving conditions of contact load P, rolling speed V_r, specific sliding S, oil viscosity η, relative radius of curvature ρ and roughness of contact surface H_<max>. Depending upon the dimensionless parameter ηV_r/P, the lubricating characteristics can be classified into three regions. And the empirical formula of the frictional coefficient in the region of semi-fluid lubrication is induced. The friction obtained under a sliding motion with rolling is very much larger than that under a pure rolling, and the maximum frictional coefficient is found for a comparatively small specific sliding. The relative radius of curvature and the roughness of contact surface have much influence upon the oil-film thickness.
