Abstract

resumo “montagem de turbomáquina, turbomáquina e métodos para montar uma montagem de turbomáquina e para desmontar uma montagem de turbomáquina” trata-se de uma montagem de turbomáquina que compreende um rotor (1) e um anel de pás (7a; 7b) montado no rotor. cada pá compreende uma porção de aerofólio (7f) e uma porção de raiz (7r) inserida em um sulco de retenção de pá circunferencial (5) do rotor (1). o sulco de retenção de pá (5) compreende uma porção de sulco ampliada. as pás na porção de sulco ampliada são giráveis ao redor de um respectivo eixo geométrico geralmente radial (y-y), para assumir uma posição de dimensão tangencial mínima. pelo menos um inserto removível (21) é disposto ao longo da porção de sulco ampliada, entre as porções de raiz das pás (7b) localizadas na porção de sulco ampliada e uma parede lateral do sulco de retenção de pá, para forçar e travar as pás em uma disposição montada final.
