摘要：
A device for damping vibration of a retention ring for axially retaining turbomachine fan blades (16), the blades being designed to be mounted via their roots (14) on a rotary disk (10) having an annular flange (18) extending axially and provided with a plurality of radial crenellations (20) for coming into contact with a plurality of complementary radial crenellations (32) of a retention ring (30) designed to be mounted around the disk flange, the device comprising an abutment element (38) of elastomer material designed to be received axially between two adjacent crenellations (20) of the flange and two adjacent complementary crenellations (32) of the retention ring, and radially between the flange (18) of the rotary disk and the retention ring (30), said abutment element presenting contact surfaces (40, 44) for coming into contact with the adjacent crenellations, with the retention ring, and with the flange of the rotary disk.
