Abstract
In order to examine the effects of the D-value and the hardness on the pitting fatigue life and the surface durability synthetically, data from 38 series of roller tests and 2 series of gear tests which were conducted under a sliding-rolling contact condition with various lubricating oils using various specimens with different hardness of HV170 to HV540 finished by various methods are considered in this paper. It is consequently clarified that the surface durability is proportional to the hardness and this tendency is changed by the surface roughness and the D-value, the relationship between the D-value and the pitting fatigue life N is not absolute with some dispersion even under the same hardness condition, the D-value at endurance limit, i.e., D_<lim> tends to increase as the hardness and the surface roughness increase, and as to an equation of σ_<Hlim>=aD_<lim>^<3.85> between the Hertzian stress at endurance limit σ_<Hlim> and the D_<lim> introduced by the defined equations of the Hertzian stress and the D-value, value of a tends to decrease as the hardness and the surface roughness increase.
