A gearwheel includes a gearwheel body with teeth arranged around its rotational axis. Two adjacent teeth are connected to one another at their tooth roots via a tooth base. The gearwheel includes a supporting structure which has a supporting region at least one or both axial ends of the respective tooth base, which supporting region extends away from the tooth base between the respective adjacent teeth. The supporting regions are connected directly to the adjacent teeth and the tooth base in each case by way of a transition region. The respective transition region surrounds the supporting region in a manner which extends at least partially and contiguously and has a transition geometry in cross section as viewed in the direction of its extent. A geometric variable of the said transition geometry changes steadily, depending on the supporting region, along an axial and/or radial direction with regard to the rotational axis.

Gearwheel with supporting structure

An internally pressurized component is provided that includes a main body having at least one cavity; at least one branch having a bore which runs through the branch into the cavity of the main body; at least one separate insert element which is arranged in frictionally locking fashion at least partially in the bore of the branch. The component, at least in that region of the bore at which the separate insert element is arranged, is formed, by way of an autofrettage treatment, as a compacted wall region, and the separate insert element is arranged with an oversize in the bore.
