Sažetak
One of the most common reasons for failures in spur gears is bending fatigue in the root of its teeth which mostly occurs as a consequence of cyclic nature of stresses at tooth root. As a result, microcracks may start to form in the root of the gear teeth, increase in size and propagate to surface, leading to a place of crack initiation and eventually breakage of the teeth. Finite element method (FEM) is one of many tools used in understanding the stress cycle. However, when one is to use FEM, numerical models must be adequately generated or the method might produce wrong results. One of the most important aspects of FEM analysis when creating the models, are finite elements and depending on the type, they have different degrees of freedom, hence might produce different results. If one is to adequately simulate the stress cycle of the gear tooth, it is important to conduct the simulation as accurately as possible, that is, to include as many aspects of real life problems as possible in the simulation, e.g. the effect of friction on the nominal tooth root stress cycle.
