Turbomachine rotor flange and assembly of this flange to a rotor

摘要

Flange (20) engaged on a rotor (21) of complementary shape. The assembly means consist of rims (25, 30) nested together by virtue of notches (29, 31) and a peg (32) for preventing rotation located away from the rotor disc (hub) (21) and engaged between the mounts of consecutive blades (22). Tool points (36) are provided close to the peg (32) in order to bend the flange (20) back at this point and disengage the peg (32) during the angular locking movement. Application to turbomachines of aircraft engines. <IMAGE>
