Abstract:

Two friction machines were designed to investigate the effectiveness and mechanism of action of lubricants under conditions of rolling and boundary sliding friction. Various forms of friction can be studied on these machines at temperatures of up to 800 degrees in open air, in the presence of various gases, and in deep vacuum. The rotation rate of one of the friction surfaces varies from 1.5 x 10 to the -4th power to 3200 rpm. The loads applied to the friction surface vary from 5 to 500 kg, which corresponds to the possibility of conducting experiments at contact pressures ranging from several to 50,000 kgsq cm. Results of tests conducted with these machines indicated that at boundary friction of metals steel hydrocarbon lubricating media in the absence of O and O-containing organic compounds do not develop the lubricating effect.
