Determination of Load Carrying Capacity of Lubricating Oil by I.A.E. Type Gear-Lubricant Testing Machine

Abstract

In this article, effect of E.P. additives on the load carrying capacity by I.A.E. type machine, was discussed and compared with results obtained by Timken and Soda four ball machine. Then commercial mild E.P. and E.P. type gear oils in Japan were tested by these testers. It was found that it was possible to use I.A.E. type machine for evaluation of load carrying capacity of mild E.P. type gear oil but not for E.P. type one.
