Gearwheel with supporting structure

Gearwheel with a rotational axis having a gearwheel body with teeth which are arranged distributed around the rotational axis, in each case two adjacent teeth being connected to one another at their tooth roots via a tooth base, and

• a supporting structure which has a supporting region at at least one or both axial, with regard to the rotational axis, ends of the respective tooth base, which supporting region extends away from the tooth base between the respective adjacent teeth,
• the supporting region being connected directly to the adjacent teeth and the tooth base in each case by way of a transition region,
• the respective transition region surrounding the supporting region in a manner which extends at least partially and contiguously, and having a transition geometry in cross section as viewed in the direction of its extent, a geometric variable of the transition geometry changing steadily, per supporting region, along an axial or radial direction with regard to the rotational axis, and
• the transition region having a first section for the direct connection between the respective supporting region and a first one of the adjacent teeth, a second section for the direct connection between the supporting region and a second one of the adjacent teeth, and a third section which connects the first section and the second section for the direct connection between the supporting region and the tooth base which connects the first and second teeth.
