ABSTRACT:
A locking device for releasably fastening parts to rotors of fluid flow machines, the base portions of the parts to be secured fitting in a form-locking manner in at least approximately axially extending fixing slots provided at the circumference of the rotor, the locking device including fixing elements which can be inserted into depression means extending transversely with respect to the axially extending fixing slots and provided in the rotor and into recesses provided in the base portions of the parts to be secured. The depression means are provided at the region of the axially extending fixing slots and divide the flanks of each such axially extending fixing slot into approximately equal parts and the recesses provided in the base portions of the parts to be secured in the assembled condition of such parts coincide with the depression means. The fixing elements simultaneously engage with both the depression means at the region of the fixing slots and the recesses in the base portions of the parts to be secured to the rotor, and such fixing elements during assembly and disassembly thereof can be removed from either the depression means or the recesses.
