ABSTRACT:
A fastening device for fastening moving blades to a disk of a turbomachine rotor includes moving-blade roots which have a mirror-symmetrical cross section with projections, axial disk slots holding the moving-blade roots in a positive-locking manner, and one riveted joint per moving blade for axially fixing the latter. Each blade root and the disk, in the region of each moving-blade root, have axial extensions. The extensions of moving blade and disk are opposite one another in pairs, in each case a hole lying in a radial plane relative to the disk axis is formed half in the extension of the moving blade and half in the extension of the disk. A rivet is inserted into each hole and fixed by plastic deformation.
