The simulation of rolling contact fatigue strength of traction drive elements was proposed. It can account for both the distribution of sizes of inclusions in the element material and the influence of traction forces at the element surface. In this study, the influence of crowning radius on the rolling contact fatigue strength was examined by using this simulation. To consider the effect of crowning radius, the simulated imaginary roller was changed to the multilayered one. Because of the increase of the number of large inclusions with increasing critical volume, the calculations using this improved simulation resulted in the decrease of rolling contact fatigue strength with the increasing crowning radius.
