Zusammenfassung:	PROBLEM TO BE SOLVED: To improve the joint of the blade of a turbo machine to a rotor shaft. SOLUTION: This device for joining a blade to a turbo machine includes a first fork end affixed to the blade, a second fork end affixed to the rotor shaft, and at least one joining bolt. The first fork end includes several first foot brackets with a first bore, and the second fork end includes several second foot brackets with a second bore. The joining bolt is inserted into the first and second bores to join the first fork end to the second fork end. The joining device includes a first area having a predetermined first diameter difference between the first diameter of one bore and the first diameter of the joining bolt and a second area having a predetermined second diameter difference between the second inner diameter of one bore and the second outer diameter of the joining bolt. The first diameter difference and the second diameter difference are different, particularly, dimensionally different from each other. COPYRIGHT: (C)2010,JPO&INPIT
