Abstract
The invention relates to the toothing of a gearwheel having a plurality of teeth, the tooth flanks of which have a main region and a tooth root region; wherein the tooth root region extends from a root circle (FP) as far as a main circle (dH), as considered in the end section or normal section through the axis of rotation of the gearwheel. The invention is characterized in that, as considered in each case in the end section or normal section, the tooth flanks in the tooth root region are designed as a Bézier curve from a relevant diameter (dr) in the direction of the tooth root; the Bézier curve merges in each case at a main point (P0, P3) in the relevant diameter (dr) in a continuous tangent into the tooth profile of the main region.
