抄録

The experiments were carried out with several lubricating oils of the same group, which were of different viscosities and were separated by reduced pressure distillation. The results obtained were as follows; (1) The reasonable experimental conditions for wear testing were determined by preliminary experiments in which the relations between the contact pressure or the friction velocity and the wear loss were observed. For these experiments hardened bearing steel was used as test specimens in combination with S55C sorbitic carbon steel. The degree of adhesional wear depended on the strength of the oil film formed on the metal surface; when the strength of the oil film increased, the adhesional wear was observed in the higher velocity of pressure region. (2) The efficiency of lubricating oils for the reduction of wear loss depended remarkably on the oil film strength and the coefficient of boundary friction. Experiments under conditions of prolonged mechanical wear also was carried out to verify the above mentioned relation and to compare the lubricating efficiency various lubricating oils.
