Abstract
The invention relates to a bevel gear wheel (1) of a bevel gear unit, each tooth (2) of which comprises a load flank (3) and a non-working flank (4), wherein the teeth (2) have a helical or spiral tooth trace, in particular a curved tooth longitudinal line, and the teeth (2), in particular the upper meshing region of the teeth, have an octoid tooth shape or a spherical involute tooth shape, and the teeth have an excess material quantity (11) on the load flanks (4) in order to reinforce the load flanks (4), in particular such that the axis (9) that runs through the tooth tip-bisecting point A1 of the tooth tip transverse line (23) and through the midpoint of the gear wheel exhibits asymmetry of the teeth (2). The invention further relates to a method for producing a bevel gear wheel (1) according to one of the preceding claims, in which the tooth geometry is produced by a four-axis or multi-axis method, in particular a five-axis method.
