Abstract
A spur gear includes a radially outer, spur-cut gear rim, a radially inner hub, and a rotationally symmetrical radial connecting structure which integrally connects the gear rim to the hub. The radial connecting structure has mutually spaced struts, which extend between the hub and the gear rim, and axial perforations or holes, which are situated between the struts. The radial connecting structure has a disk-shaped base body, through which the axial holes pass and which has an axial front side and an axial rear side, with the struts being situated on the front side.

A spur gear, comprising:
- a radially-outwardly-disposed spur-cut gear rim;
- a radially-inwardly-disposed hub;
- and
- a rotationally symmetrical radial connecting structure connecting said gear rim to said hub;
- all of said gear rim, said hub, and said radial connecting structure being integrally formed as one single piece;
- said radial connecting structure having mutually spaced-apart struts extending between said hub and said gear rim and forming axial perforations between said struts;
- said struts including a set of struts of a first type and a set of struts of a second type,
- said set of struts of said first type and said set of struts of said second type each having a profile with a width and a height;
- said height of said profile of said set of struts of said first type being greater than said width of said profile of said set of struts of said first type;
- said width of said profile of said set of struts of said second type being greater than said height of said profile of said set of struts of said second type;
- and
- said radial connecting structure having a disk-shaped base body penetrated by said axial perforations, said base body having an axial front side and an axial rear side, and said struts being disposed only on said front side of said base body.
