Abstract
A process for improving the excitation behavior of a ground bevel gear set by altering the surface structure of a gear set member from tooth slot to tooth slot (Teeth 1-3). The method comprises shifting the roll-positions in a way that not every facet or flat (F) is positioned the same way on each flank (2) and/or changing the distances of the roll angle along a tooth slot (delta RPj) whereby flats are spaced unequally (i.e. varying widths) along the tooth. One or more additional processes for altering the surface structure may be included.
