Abstract

Spur gears are the most common type of gears for industry, due to its simple structures and low costs of manufactureUnder the action of rolling contact fatigue, the main mode of the coated teeth failure is surface or subsurface originated micro-pitting, leading to the debonding of coating from substrate, fracture in the coating and even subsurface failureFailure may originate from initiation of cracks, and its growth and propagation, however, basic failure mechanism is still not clearIn this paper, a comprehensive finite element modeling procedure including submodelling techniques and irreversible cohesive zone modelling techniques (CZM) is developed to investigate the failure mechanisms under the rolling contact fatigue loadingThe details of the localized stresses distribution will be simulated using the submodelling techniqueIrreversible CZM will be used to simulate the initiation and propagation of the cracks in the coated surface of the spur gears under the cyclic contact loading.
