Abstract: The present invention relates to a gear wheel comprising an outer part (12) having a gear rim (14), an insert (16) which has an insert outer diameter (dEa) and a receptacle section (32) having an insert part inner diameter (dEi) for forming a shaft-hub connection, and a connecting part (18) which is arranged between the insert part (16) and the outer part (12) and which connects the insert part (16) and the outer part (12) in a formfitting and/or materially-bonded and/or friction-locked manner, wherein the connecting part (18) has a number of ribs (27) or the connecting part (18) is formed by a number of ribs (27), wherein the ribs (27) each extend along a tangent (T) which abuts a tangent circle (CT), wherein the tangent circle (CT) has a tangent circle diameter (dCT) which is larger than or equal to the insert inner diameter (dEi) and smaller than or equal to the insert outer diameter (dEa).

Abstract: A gear rim carrier part for a two- or multi-component gearwheel includes an annular section which revolves around an axis of rotation in the circumferential direction, a gear rim arranged radially on the outside of the annular section, and a projection which extends radially inwards from the annular section and has a radially inner free end, or the gear rim carrier part includes an annular section which revolves around an axis of rotation in the circumferential direction, a gear rim arranged radially on the inside of the annular section, and a projection which extends radially outwards from the annular section and has a radially outer free end. The projection has a first width at the radially inner free end thereof or at the radially outer free end thereof and has a second width at the opposite end thereof at the transition to the annular section.

Abstract: The invention relates to a multicomponent gear having an outer part with a toothed rim, an inner part, and a connecting part made of plastic for the positive locking connection of the inner part and the outer part. The outer part is thereby arranged on an outer circumferential surface and the inner part is arranged on an inner circumferential surface of the connecting part. The connecting part is additionally provided with a plurality of indentations on two opposite primary surfaces lying outside and perpendicular to a rotational axis. The invention is thereby characterized in that the indentations in the first primary surface of the connecting part are, in comparison to the indentations in the second primary surface of the connecting part, arranged offset to each other radially and/or in the circumferential direction to the rotational axis.

Abstract: The present invention is directed to a shaft with two front sides and an axis of rotation, whereby the shaft comprises at least one gear with the same axis of rotation, which gear borders at least a first one of the front sides in an axial area. Viewed from radially inside toward radially outside, the gear comprises a connection part with a central receptacle for the shaft, and an outer part with teeth. The connection part is cast directly between the shaft and the outer part. The connection part extends over the shaft in axial direction and covers the first front side.
