Abstract

A shaft/hub unit having a toothing assembly for transmitting torque, comprising a shaft (1) with shaft toothing (5) and a hub (2) with hub toothing (7), which sets of toothing engage one another, with torque being introduced by a shaft shank (4) at whose end there is provided the shaft toothing (5) and with the tooth profile of the shaft toothing (5), in the longitudinal direction, following a variable course, wherein the shaft toothing (5) comprises a major diameter which, in the longitudinal direction, follows a constant course and wherein the hub toothing (7) comprises a base diameter which, in the longitudinal direction, follows a constant course, wherein the toothing assembly comprises at least two axially extending portions (9, 10) in which each base diameter of the shaft toothing (5) follows a constant course and in which each major diameter of the hub toothing (7) follows a constant course, and wherein, of the each two adjoining portions, the portion facing the shaft shank (4) comprises the greater base diameter of the shaft toothing (5) and the greater major diameter of the hub toothing (7), and wherein, of each two adjoining portions, the portion facing the shaft shank (4) comprises a tooth profile of the shaft toothing (5), which tooth profile corresponds to a head portion of the adjoining portion, which head portion forms the upper part of the tooth profile.
