Abstract

"TURBORREATOR". O turborreator de acordo com a invenção compreende uma estrutura fixa, um rotor de ventilador fixado em um eixo de acionamento (5) suportado por um primeiro mancal (6) e por um segundo mancal (7), montado sobre a dita estrutura fixa através de uma parte de suporte de mancal (11, 19), o primeiro mancal (6) sendo montado sobre a estrutura fixa do turborreator através de um dispositivo (13) que habilita o ser desacoplado (13) da estrutura fixa, caracterizado pelo fato de que o segundo mancal (7) é montado sobre a parte de suporte de mancal (19) através de uma conexão atuando como uma junta de rótula (23, 24) e pelo fato de que o turborreator também compreende dispositivos habilitando os deslocamentos axiais do segundo mancal (7) com respeito à estrutura fixa do turborreator caso o primeiro mancal (6) venha a ser desacoplado. A função centralizadora do segundo mancal (7) após o desacoplamento do primeiro mancal (6) é assim proporcionada sem introduzir tensões excessivas no mancal (7).
