Abstract
"MOTOR TURBO-JATO". A presente invenção pertence a um motor turbo-jato que compreende uma estrutura fixa, um rotor do ventilador (2) integrado com um eixo de acionamento (5) suportado por um primeiro mancal (6) e um segundo mancal (7). Ele é caracterizado pelo fato de compreender um dispositivo (28) que forma um dispositivo de retenção axial para o rotor do ventilador (2) e/ou que forma um mancal de emergência que opera em conjunto com o dispositivo (32, 33) da estrutura fixa e montado integrado com o eixo de acionamento (5). Em particular ele compreende um flange estrutural (18) sobre o qual o segundo mancal é fixado (7), e o dispositivo que forma um dispositivo de retenção axial para o ventilador (2) e/ou que forma um mancal de emergência compreende um disco de retenção (28) montado no eixo de acionamento (5) e que opera em conjunto com um disco batente (33) de flange (18) para reter axialmente o ventilador (2) e com uma luva longitudinal (32) do flange (18) para formar um mancal de emergência.
