Rotor for turbomachinery

摘要

A rotor includes a disc, on which are fixed vanes, and platforms between these vanes. The rotor is particularly remarkable in that the platforms are fixed securely and tightly to the disc. To this end, the disc includes between two successive vanes an upstream stop projecting axially from the upstream surface, and each platform includes: a plate, a retaining groove extending axially and in which the upstream stop of the disc is engaged, an axial stop bearing axially against the upstream surface of the disc.

1. A rotor for turbomachinery, comprising:
a disc having rotational symmetry about reference axis, the disc comprising an upstream surface extending radially and a peripheral surface extending substantially parallel to the reference axis, the peripheral surface comprising a downstream edge, a plurality of vanes fixed to the disc, a plurality of platforms, each platform being disposed between two successive vanes, the disc comprising, between two successive vanes, an upstream stop projecting axially from the upstream surface, each platform comprising:
a plate,a retaining groove extending axially and in which the upstream stop of the disc is engaged,an axial stop bearing axially against the upstream surface of the disc.
