Abstract: One of the main disadvantages of gear mechanisms is the occurrence of noise and vibra- tions. This study investigated the applicability of non-circular gears for preventing reso- nance oscillations in gear mechanisms. The influence of a small deviation of the gear cen- trodes from the nominal circles on kinematic and oscillatory characteristics was analysed. It was shown that a larger deviation results in a smaller resonance amplitude due to mesh frequency variability and simultaneously in higher additional dynamic loads on the mech- anism. The shape of the gear centrodes was determined which provides a relatively small resonance amplitude with minimum additional dynamic loads. A mechanical device was developed to enable cutting of slightly non-circular gears on a hobbing machine without numerical control.
