Spline connection

A spline connection comprising:

• a hub including a toothing profile on an inner circumference, wherein the hub toothing profile is constant over its toothing length;
• an axle journal including a toothing profile on an outer circumferential portion and a shoulder for axial support and/or abutment against the hub;
• and
• a tensioning device for axially bracing the axle journal with the hub,
• wherein the axle journal comprises a first portion and a second portion with different toothing profiles over the axle journal's toothing length,
• wherein the first portion of the axle journal is arranged on an insertion side to be further away from the shoulder than the second portion of the axle journal, wherein the first portion of the axle journal has a constant toothing profile which has play with respect to the toothing profile of the hub, and the second portion of the axle journal is arranged on a shoulder side and has a toothing profile which has reduced tooth spaces compared with the first portion of the axle journal and which is play-free with respect to the toothing profile of the hub, and
• wherein the second portion of the axle journal is arranged such that only after the first portion of the axle journal has been inserted with play into the hub, the second portion is compressed with the toothing profile of the hub such that play is prohibited as a result of subsequent tightening of the tensioning device.
