Abstract
Geared systems present a non-linear behaviour due to time varying mesh stiffness, which is a parametric excitation, backlash and the static transmission error. Most studies about these systems often do not consider the shaft flexibilities. Previous study showed that including these flexibilities on the model might cause great difference on the results for spur gears initially assembled horizontally. The present study intends to analyze the influence of shaft flexibilities on a spur gear pair, considering unbalance and anisotropy. Results indicate that, for the adopted system configuration, horizontal motion is highly affected by unbalance.
