DEVICE FOR AXIALLY RETAINING MOVABLE BLADES ON A ROTOR DISK

摘要

The invention relates to a device comprising two open stacked rings (11, 12). At least one of the rings (11, 12) comprises a rotational abutment means (13) for engaging with at least one bracket of the disk. The two open rings (11, 12) are mounted in a discontinuous groove provided in the brackets, on the end of the teeth that are located on the circumference of the rotor disk, such that the rotational abutment means (13) of the first ring (11) is placed in the opening (15) of the second ring (12). The size of the surfaces making contact with each other between the two rings (11, 12) makes it possible to damp the vibrations during operation.
