Abstract:
1. Method for balancing rotors without journals, in which the rotor ( 2 ), which has a pocket hole bore ( 6 ), is arranged on a bearing mandrel ( 5 ) of a balancing device and fluid is brought between rotor and bearing mandrel faces located opposite one another and the rotor ( 2 ) is set into rotation, wherein oscillations of the bearing mandrel ( 5 ) induced by imbalance are used to determine the imbalance, wherein the rotor ( 2 ) is supported in a first bearing region in the radial direction by means of a liquid and in the bearing arrangement of a rotor ( 2 ) which has a pocket hole bore it is supported in a second bearing region in a presettable axial position on the bearing mandrel ( 5 ) by supplying fluid to a fluid chamber ( 40 ) positioned between the end of the pocket hole bore and the end of the bearing mandrel.
