Abstract (en)
The device has a ring (20) for retaining blades on a rotor disk of a turbomachine. The rotor disk (10) provides a set of blocking hooks (162, 164) that spread around a circumference and defines a groove for placing the ring. The ring is provided with a split and a set of cleat (302, 304), which is arranged on the ring and placed in the groove. The cleat is compressed against one blocking hook and the split is covered by another blocking hook. The former hook is provided with a check face that cooperates with a contact face brings the cleat next to the split. Independent claims are also included for the following: (1) a ring for retaining the blades of a turbomachine rotor (2) a disk/ring assembly of a turbomachine (3) a turbomachine rotor (4) an aircraft engine.
