    Abstract

    An analysis of the rolling contact tatigue process of case-hardened gear material by means of clasticity and fracture mechanics theory has been made: the stress intensity range Δk and equation for crack growth da/dN = ck)″ was put forward to calculate their fatigue life and strength in this work. The results show that the calculated data are in good agreement with the experimental ones for compound-treated, sprayed, and carbonitrided specimens. The relative errors of logarithm of cycle number are all less than 5′
