Abstract
Machine having a rotor which is mounted in a cantilevered fashion on a bearing and has a rotational axis along which a free, subsequently non-mounted rotor end runs starting from the bearing, the rotor end having a rotor end side which is spaced apart from a fixed rotor opposing side by a gap, and which, during operation of the machine when the rotor is rotating, is deflected with respect to the rotational axis as a result of imbalance of the free, non-mounted rotor end, or as a result of externally applied forces, wherein the rotor end side is curved or beveled so as to drop away at least in its end region towards its edge and in a direction towards the bearing.

A machine comprising:
- a stator;
- and
- a rotor that is rotatable around a central axis and has a first end and an opposite second end, the first end of the rotor being mounted to a bearing and the second end of the rotor being non-mounted in a cantilevered fashion,
- the second end of the rotor having an end side surface,
- the end side surface having a center intersected by the central axis when the rotor is stationary,
- wherein the end side surface positioned adjacent to an opposing side surface of the stator to form a sealing gap therebetween, and
- wherein the end side surface being curved or beveled in an edge region providing a free space between the end side surface and the opposing side surface of the stator for the edge region of the end side surface when the second end of the rotor experiences deflection with respect to the central axis during operation of the machine.
