Abstract

um conjunto rotativo para uma turbomáquina inclui um rotor que compreende dois pavimentos rotor consecutivas (10a, 10b) provido de uma pluralidade de pás móveis (20) e uma colar de rotor (50) anular que liga as ditas duas fases consecutivas do rotor; um estator que tem uma fase de estator (11), provida com uma pluralidade de pás estacionárias (30) e dispostas entre as ditas duas fases de rotores e um anel de estator anular (60) montado nas ditas pás; em que um (50) dos elementos do anel de rotor e o anel de estator transporta, pelo menos, um cursor (51) configurado para cooperar com uma pista abradável (62) suportado pelo outro (60) dos ditos elementos, tais que o colar do rotor compreende, pelo menos, uma das suas extremidades a montante e a jusante, uma porção de contato do tipo oblíquo (154) que assenta sobre uma superfície de apoio oblíqua (173a) da fase do rotor correspondente, a superfície de apoio sendo a superfície externa de uma projeção (173) que se projeta a partir de uma porção de base (127) da fase de rotor correspondente.
