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.
