Patent ID: 8424408

Claim:
A gearing of a gearwheel having a plurality of teeth; wherein: the plurality of teeth include tooth flanks having a useful area and a tooth base area; the tooth base area extending, viewed in normal section, from a base circle up to a useful circle; the tooth flanks of teeth which are adjacent in normal section each being implemented symmetrically to one another, the axis of symmetry (y) intersecting the base circle in the base point; characterized in that the tooth flanks in the tooth base area are implemented as a tangent function from a relevant diameter (d r ) in the direction of the gearwheel center point; the tangent function merges in the relevant diameter (d r ) in a constant tangent into the tooth flank form of the useful area; the tangent function merges in the tooth base area in a constant tangent into an orbit, which is tangentially applied to the base circle (d f ) in the base point (FP).
