FIELD: mechanics.
SUBSTANCE: device for blades fixing to turbo machine rotor disc in axial direction consists of a ring and ring lock. The ring is fixed to the circular disc groove by means of inner radial edge and rests upon the blade roots by outer radial edge. The blade roots are installed in grooves along disc periphery. The ring lock is located in circular disc groove to prevent ring turning in the above circular groove. The ring lock can rotate in circular groove between ring locking position and position for installation and removal.
EFFECT: invention allows for simplifying processes of manufacture, installation and removal of ring from rotor disc and reducing ring damage during its installation on disc.
