Rotor blade for a flow machine, and an associated pulling-off tool

摘要

A rotor blade ( 1 ) for a flow machine includes an aerodynamic blade ( 2 ) and a foot ( 3 ). The foot ( 3 ) has an anchoring section ( 5 ) on a side facing away from the blade ( 2 ). A rotor ( 4 ) of the flow machine has an axial anchoring groove ( 6 ) which is complementary to the anchoring section ( 5 ). The anchoring section ( 5 ) can be inserted axially into the anchoring groove ( 6 ) in order to radially attach the rotor blade ( 1 ) to the rotor ( 4 ). At least one pulling-off contour ( 7 ) is formed on the foot ( 3 ), via which an axial pulling-off force can be introduced into the rotor blade ( 1 ), which is attached to the rotor ( 4 ) with the aid of a pulling-off tool ( 15 ) which is complementary to this pulling-off contour ( 7 ).
