Abstract: A gearwheel pairing for a helical gearing, comprising a helical gear with a first toothing segment, and a worm with a second toothing segment, wherein the first toothing segment and the second toothing segment can be brought into intermeshing and form an involute toothing when intermeshed, the materials of the first and the second toothing segments are chosen such that when intermeshed there results a plastic-metal material pairing, and the toothing segment made of plastic has a first normal tooth thickness and the toothing segment made of metal has a second normal tooth thickness, wherein the ratio of the first normal tooth thickness to the second normal tooth thickness is increased by 10 to 200% with respect to a reference profile.

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).
