Abstract
A turbomachine rotor wheel comprises a disk carrying blades having roots engaged and held in an annular recess of the disk, the roots being connected to platforms for co-operating with an annular gasket mounted in an annular groove of the disk, the annular sealing gasket exerting a resilient force on the blade platforms holding the blades in a proper position for operation while the turbomachine is at rest.
Claims11
A rotor wheel, in particular for a turbomachine, the wheel comprising a disk carrying blades having roots engaged and held in an annular recess in an outer peripheral surface of the disk, the roots being connected to platforms surrounding the outside of the outer peripheral surface of the disk and designed to co-operate with an annular sealing gasket mounted in an annular groove of the outer peripheral surface of the disk, wherein, at rest, the annular gasket exerts a resilient force on the blade platforms holding the blades in a proper position for operation, the annular gasket in the free state having an outside diameter greater than that of its mounting groove, and its hardness being determined so as to urge the blades into their proper position for operation and so as to allow the blades to be moved circumferentially in their annular mounting recess.
