The device is composed of a conical section located on the edge of the disk rim. The greatest radius of the conical section is at least equal to the radius of the circumference passing through the bottom of the axial grooves into which the blade roots are inserted. A groove is formed in the end of the lower part of the root, this groove having a right angle triangular section. A locking part has one face pressed against the bearing and two other faces against the sides of the groove in the root. A blade extending longitudinally in the locking part works together with a groove in the slot of the blade root to keep the locking part in place.

An axial locking arrangement for turbomachine blades having shanks mounted in axial first slots of a rotor disk, said first slots including means for radially locking said blades, said axial locking arrangement comprising: at least one conical bearing surface formed on an axial rim of said rotor disk, the maximum radial position of said bearing surface being at least equal to a radius of a circumferential line passing through the bottom of said first slots; a second slot in a lower surface of at least one end of each said shank, the length of each said second slot extending parallel to the plane of said disk when said shanks are mounted in said first slots; locking means individually inserted in each said slot, each said locking means being formed of a piece shaped to be inserted in said second slot in a direction having a radial component and to bear against one said bearing surface and walls of said second slot when inserted in said second slot and when said shank is in said first slot; and means separate from said locking means for circumferentially fixing said locking means within said second slot.
