Analysis of the impact of non-parallelism of shafts' axes on the contact area of cooperating teeth and gearbox's components vibrations

In this article, the results of experimental research and simulation studies using a geometric model made in CAD software were presented. The aim of the conducted research and simulations was to determine the influence of non-parallelism of shafts' axes on gearbox vibroactivity and the contact area of the cooperating teeth. The results showed that the change of the non-parallelism of shafts' axes significantly affects the vibrations of selected components of the operating gearbox and the contact area of cooperating teeth.
