Computerized generation, simulation of meshing and advanced contact stress analysis of spiral bevel gears via a new approach

The alternative formulation of the theory of gearing presented in [1], which does not need an early estabilishment of reference systems like in [2], is applied to model the grinding process of a real spiral bevel gear drive for aerospace applications. All the information collected about the geometry is employed to generate a finite element model capable of giving accurate results in terms of contact tractions and subsurface stresses during meshing. A description of the operating procedure followed to create and successfully run the model in a commercial finite element code (Ansys) is given which allows to obtain accurate stress results with a reasonably low computing time.
