Abstract

The invention relates to a gear pair consisting of a crown gear (1) and of a pinion gear (2) provided in the form of a spur gear with an axis crossing angle of 90°. According to the invention, the teeth (3) of the pinion gear (2), in order to reduce an undercut of the teeth (5) of the crown gear (1), have a pressure angle, which increases from the outside inward in a radial direction with regard to the crown gear (1), or in the event of a constant pressure angle, have a profile offset, which decreases from the outside inward in a radial direction with regard to the crown gear (1).
