Computational modelling of surface pitting of gears using EHD-lubrication conditions
Glodež, Srečko ; Fajdiga, Gorazd ; Jelaska, D...
The paper presents a computational model for the simulation of surface initiated fatigue crack growth on gear teeth flanks. A simple contact model is used for simulating fatigue crack growth under ...conditions of rolling and sliding contact. The contact model is subjected to moving normal (normal contact pressure) and tangential (frictional forces) contact forces, which also take into account the influence of EHD-lubricaion conditions, the associated lubricant pressure acting on crack faces, and residual stresses due to the heat treatment of the gear material. The virtual crack extension method in the framework of finite element analysis is used for simulation of the fatigue crack propagation, from the initial crack up to the formation of the surface pit. On the basis of the results it can be concluded that the initial surface crack of length 15 ▫$\mu$▫m with the considered boundary conditions lead to the appearance of very small surface pits, which can be termed as micro-pitting on the gear teeth flanks. Consequent computational determination of the functional relationship K=f(a) enables the estimation of the service life of gears in regard to the surface pitting, if combined with the previously developed models. In addition, the model can be further improved when additional contributions from theoretical and numerical research become available, coupled with new data from more refined experimentation.
