Abstract
The Lubricational characteristics of O/W Emulsions of beef tallow and mineral oil based lubricants are studied in a roller on disk apparatus. It is revealed that the coefficients of friction with both emulsion lubricants exhibit essentially similar behavior; that is, they rapidly decrease to 0.1% concentration and after they constants with increasing oil concentration, and that, with oil in water emulsions of a concentrations as low as 5wt% practically forms a elastohydrodynamic film. One hand, surface temperature effect on lubricants has virtually no severe, and that, the minimum EHL film chickness estimated that it begins to increase at a concentration of several percent; the effect of particle diameter becomes maked there after.
