FIELD: mechanical engineering. SUBSTANCE: proposed blade locking device with hammer-like fasteners for fastening blades in groove of turbomachine wheel disk contains housing whose cross section is like cross section of groove, locking member movable in radial direction fitted in through hole provided in housing with possibility of partially locating in seat of lock, and locking member moving screw. Locking member is provided with stops capable of moving in ports of housing. Head of screw has considerably large size and it can be radially fixed between bottom of groove and base of housing. Such design of device prevents loosening of tightening and jamming of screw thread in process of mounting. EFFECT: improved reliability in operation. 4 cl, 11 dwg
