Abstract

Abstract Translated from French Afin de permettre le réglage en position de l'anneau intérieur d'un stator à ailettes à calage variable d'une turbo-machine, chacun des secteurs (7) de cet anneau est pourvu de points de réglage constitués de douilles (14) de paliers de pivot de pieds des ailettes (2) qui comportent un filetage externe coopérant avec un taraudage complémentaire de leur logement et viennent en appui contre un épaulement des pivots (5) de sorte que la position radiale de chacun des secteurs (7) peut être ajustée par rotation des douilles dans leur logement. In order to allow the adjustment in position of the inner ring of a stator with variable-pitched fins of a turbo-machine, each of the sectors (7) of this ring is provided with adjustment points constituted by sockets (14) of pivot bearings of the feet of the fins (2) which have an external thread cooperating with a complementary tapping of their housing and come to bear against a shoulder of the pivots (5) so that the radial position of each of the sectors (7) can be adjusted by rotation of the sockets in their housing.
