Sealing and retention device for a rotor notched with pinouts receiving blade roots.

摘要

P Sealing device for a rotor (6) notched with axial pinouts receiving blade roots (9). BR/ We have circular sealing parts (1, 2), one of which is a flange (1) masking the pinouts and the other is a rod (2) supported by conical surfaces (23) so to push the flange (1) axially. The flange (1) is supported on protrusions (15) of the rotor (6) or of the blades (9) and is not compressed at the bottom of the grooves, no more than the ring (2), which limits the damage and the wear and tear of these regions. BR/ The invention applies to turbomachines, in particular aircraft engines. /P
