The study deals with the meshing characteristics of cylindrical helical external gear pairs. The gear pairs, following the nowaday’s strength and quality requirements are becoming ever smaller. Accuracy in the background also attracts the importance of vibration and noise reduction. The inclined tooth meshing, in contrast to the straight tooth, due to the specificity of its zone of contact, is the subject of this study. This is of special importance because the meshing stiffness varies for one to more teeth pairs, the meshing contact lines are of continuously varying length during meshing, and as a consequence load sharing and distribution is changing with. This paper deals with the zone of contact and its geometric modification in order to light on a new type of vibrational excitation.
