Abstract
A shaft system includes a shaft having a first shaft portion. The first shaft portion has a profile which is formed in the radial direction, extends in the axial direction, has a constant cross-section in a first region, and is open in the axial direction towards a first side of the shaft portion. In a second region of the first shaft portion adjoining the first region, the profile has a taper in the direction of a second side opposite the first side. A peripheral groove extending in the circumferential direction is introduced between the first region and the second region and forms a first groove flank in the first region and a second groove flank in the second region. The second groove flank forms an axial boundary for the profile in the first region towards the second side. Also disclosed is an electric machine comprising said shaft system.
