Abstract

A spline connection having a hub with a toothing profile on the inner circumference, an axle journal having a toothing profile on an outer circumferential portion, a shoulder for axial support and/or abutment against the hub, and a tensioning device for axially bracing the axle journal with the hub. The hub has a constant toothing profile and the axle journal has a first portion and a second portion with different toothing profiles. The first portion is arranged on the insertion side to be further away from the shoulder than the second portion and has a constant toothing profile with play with respect to the toothing profile of the hub. The second portion is arranged on the shoulder side and has a toothing profile which has reduced tooth spaces compared with the first portion and which is play-free with respect to the toothing profile of the hub.
