Abstract
As the material’s intricate stresses and strains are always shifting during phases of loading, determining the predicted equipment working under rolling-sliding contact loads and their fatigue lives (wheels, bearings, and gears) is particularly difficult. Another difficulty is not knowing the precise characteristics of the material used to make the components, which is particularly noticeable. when it comes to heat-treated components, where the material characteristics’ values can differ greatly among the equipment. Depending on the findings of fatigue measuring involute spur gears constructed of 42CrMo4 steel that has undergone various heat treatments. According to recently published findings, the previously suggested multiaxial fatigue life measurements methodology as reported by the Fatemi-Socie critical plane-based crack start criterion was used to conduct fatigue life studies of the flanks of gear teeth. Due to the lack of real cyclic and fatigue material factors, an estimating method particularly designed for 42CrMo4 steel was used, utilizing the materials’ monotonic properties as provided in previous studies. Very good agreement is found between investigational and computed fatigue lives, or load carrying capacities, indicating that advanced material parameter estimation is applicable to studies of genuine elements’ fatigue and inability under rolling sliding contact loads.
Keywords: monotonic, rolling sliding, exceedingly
