Abstract
MÁQUINA GIRATÓRIA. Trata-se de uma máquina giratória que compreende um eixo (14), um revestimento (12), pelo menos um mancal magnético principal conectado ao eixo para sustentar de modo giratório o dito eixo dentro do revestimento, pelo menos um primeiro e um segundo mancais de rolamento auxiliares (20, 22) posicionados entre o eixo e o revestimento para sustentar cargas axiais e radiais, e primeiro e segundo meios de apoio axiais (44, 54) posicionados sobre o eixo para transmitir cargas axiais aos anéis internos dos mancais de rolamento. A máquina compreende adicionalmente um espaçador (28) posicionado axialmente entre as faces voltadas umas para as outras dos anéis internos (20a, 22a) dos ditos mancais de rolamento para a transmissão das cargas axiais entre os ditos anéis internos e pelo menos um primeiro meio de retenção axial (58) posicionado sobre o revestimento e localizado axialmente entre as faces voltadas umas para as outras dos anéis externos (20b, 22b) para a transmissão das cargas axiais entre pelo menos um dentre os ditos anéis externos e o revestimento.
