摘要

A locking device for enabling the circular locking of a set of blades provided with a hammer base on the rim of a turbine engine compressor hub is disclosed. The rim includes a peripheral groove on the outer surface thereof for receiving the bases of the blades of the set and two shoulders framing the groove with surfaces which form bearings for holding the blades; and a cut-out provided in at least one of the shoulders to enable the bases of the blades to be inserted in the groove. The locking device translatably immobilizes the blades in the groove and is positioned in the groove between two consecutive blades and in turn translatably held in the groove by an attachment device. A carrier is shaped so as to fit into the cut-out and to rest circumferentially on at least one engagement surface of the shoulder.
