Evaluation of Topological Modification on Gear Wheel Bodies

: Paper was devoted to introduction of various methods regarding the possibilities of optimization of gear wheel body shape. Evaluation was done by a finite element analysis, which gave a deformation results of a gearing, and also by comparison of weight loss. This optimization was performed by modeling 5 models of gear wheel bodies of which, one was reference one and other four had relieve elements modeled. Each model was compared to the reference one in first step by weight loss and deformation values. In the second step the analysis was conducted taking into account both evaluations, which result was a choice of best variant.
