ROTATING MACHINE

A rotating machine ( 10 ), in particular a compressor or turbine, has a rotor shaft ( 11 ) which is rotatable about an axis ( 20 ) and is provided with at least one slot ( 14 ). The mechanical stresses in the region of the slot are reduced in that the at least one slot ( 14 ) has a slot bottom ( 17...

Beschreibung
Zusammenfassung:	A rotating machine ( 10 ), in particular a compressor or turbine, has a rotor shaft ( 11 ) which is rotatable about an axis ( 20 ) and is provided with at least one slot ( 14 ). The mechanical stresses in the region of the slot are reduced in that the at least one slot ( 14 ) has a slot bottom ( 17 ) with an elliptic cross-sectional contour ( 24 ).
