Abstract

A rapid method for measurement of the rolling contact fatigue limit of case-hardened gear materials was developed according to Miner theory [1] by step loading. For performing the fatigue test by the rapid method, only one specimen is needed and no more than a few hours of testing are required. With respect to the conventional method it can increase testing efficiency by a hundred times. The relative error of the resulting fatigue limit is less than 5%.
