Rolling and Rolling-Sliding Contact Fatigue Failure Mechanisms in 32 CrMoV 13 Nitrided Steel—An Experimental Study

open access: yesApplied Sciences, 2021
The aim of this work is to characterize the rolling and rolling-sliding contact fatigue failure mechanisms on the 32CrMoV13 nitrided steel. During rolling contact fatigue tests (RCF), two general features were observed: specimens presenting short lives ...

Microstress cycle and contact fatigue of spiral bevel gears by rolling-sliding of asperity contact

open access: yesFriction, 2020
The rolling contact fatigue (RCF) model is commonly used to predict the contact fatigue life when the sliding is insignificant in contact surfaces. However, many studies reveal that the sliding, compared to the rolling state, can lead to a considerable ...

Simulation of Rolling Contact Fatigue Strength for Traction Drive Elements

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2013
A simulation of the rolling contact fatigue strength of a traction drive element was proposed. The simulation can account for both the distribution of sizes of inclusions in the element material and the influence of traction forces at the element surface.
