THE INVENTION REFERS TO A METHOD FOR RECONDITIONING A ROTOR (10) OF A TURBOMACHINE, WHICH IS EQUIPPED WITH CIRCUMFERENTIALLY EXTENDING ROTOR GROOVES (12) FOR ACCOMMODATING ROTOR BLADES (13) WHICH ARE RETAINED IN THE ROTOR GROOVES (12) AT A DISTANCE FROM EACH OTHER BY MEANS OF SPACERS. THE METHOD COMPRISES THE FOLLOWING STEPS: A) REMOVING THE ROTOR BLADES (13) AND SPACERS FROM THE ROTOR GROOVES (12) WHICH ARE TO BE REWORKED; B) HOLLOWING OUT THE EXPOSED ROTOR GROOVES (12) WITH SIMULTANEOUS WIDENING OF THE ROTOR GROOVES (12) IN ORDER TO REMOVE DAMAGE-INFLICTED MATERIAL; C) INTRODUCING AT LEAST ONE CIRCUMFERENTIALLY EXTENDING LATERAL GROOVE (21) IN EACH CASE FOR ACCOMMODATING A FILLER PIECE IN THE ROTOR GROOVES (12) IN SUCH A WAY THAT A GAP BETWEEN ROTOR BLADES (13) AND HOLLOWED-OUT ROTOR GROOVES (12) IS FILLED OUT BY MEANS OF THE FILLER PIECE; D) PROVIDING NEW SPACERS (15?) WHICH ARE MATCHED TO THE HOLLOWED-OUT ROTOR GROOVES (12) AND HAVE RECESSES (17) WHICH ARE MATCHED TO THE INTRODUCED LATERAL GROOVES (21); E) PROVIDING FILLER PIECES FOR INSERTING INTO THE CIRCUMFERENTIALLY EXTENDING LATERAL GROOVES (21) AND RECESSES (17) OF THE NEW SPACERS (15?); AND F) INSERTING THE ROTOR BLADES (13) AND NEW SPACERS (15?) INTO THE HOLLOWED-OUT ROTOR GROOVES (12) AND ALSO INSERTING CORRESPONDING FILLER PIECES INTO THE LATERAL GROOVES (21) AND MATCHED RECESSES (17) OF THE NEW SPACERS (15?). (FIG. 4) |
