Patent ID: 8459952

Claim:
A connection device for connecting a blade ( 1 ) to a rotor shaft ( 16 ) of a continuous flow machine, comprising: a first fork foot ( 2 ) fixedly connected to a blade ( 1 ), said first fork foot ( 2 ) having a plurality of first foot lugs ( 4 ) each with a first bore hole ( 5 ); a second fork foot ( 6 ) fixedly connected to said rotor shaft, said second fork foot ( 6 ) having a plurality of second foot lugs ( 7 ) each with a second bore hole ( 8 ); at least one connection bolt ( 9 ) which passes through said first bore holes ( 5 ) and said second bore holes ( 8 ) in an axial direction for connecting said first fork foot ( 2 ) to said second fork foot ( 6 ); a first cylindrical area ( 11 ) having a predetermined first diameter difference (ΔD 1 ) between a first inner diameter (d 1 ) of one of said first bore holes ( 5 ) and said second bore holes ( 8 ) and a first outer diameter (D 1 ) of said connection bolt ( 9 ); and a second cylindrical area ( 12 ) having a predetermined second diameter difference (ΔD 2 ) between a second inner diameter (d 2 ) of one of said first bore holes ( 5 ) and said second bore holes ( 8 ) and a second outer diameter (D 2 ) of said connection bolt ( 9 ); wherein said first diameter difference (ΔD 1 ) and said second diameter difference (ΔD 2 ) differ from one another; and wherein said first outer diameter (D 1 ) and said second outer diameter (D 2 ) differ from one another.
