ABSTRACT:
A press fit between a spline shaft and a spline hub is disclosed. The spline shaft has, on one end region, a spline-shaft toothing arranged on the outside and the spline hub has an inner spline-hub toothing which corresponds essentially to the spline shaft toothing. In the prefabricated state, the spline hub toothing is provided with an undersize in relation to the spline-shaft toothing. Those edges of the tooth flanks of the spline-shaft toothing at the front on the insertion side are designed as cutting edges which, during the insertion of the spline shaft into the spline hub come into engagement with a chipping effect on the tooth flanks of the spline-hub toothing. So as to avoid a risk emanating from these chips, the depth of insertion of the spline shaft into the spline hub is limited by a shoulder, and the distance between the cutting edge and the shoulder is smaller than the extension of the spline hub. As a result, the chips remain within the spline-hub toothing of the spline hub.
