The gearing (9) has tooth formed in a wedge shape such that geometrical lines coincide centrally in a common point on a rotation axis (1a). The tooth extends radially to the rotation axis. Tooth flanks are inclined to a partition level at a flank angle larger than twenty degree and smaller than thirty degree, where the partition level symmetrically portions the tooth. A tooth gap is rounded in a concave manner between the flanks with a base radius, where head radius is larger than base radius. The flanks lie opposite to each other at the tooth gap. An independent claim is also included for a wheel bearing arrangement with a spur gearing.
