Abstract

"DISPOSITIVO PARA VEDAçãO ENTRE UM EIXO ROTATIVO E UM ALOJAMENTO FIXO". A presente invenção refere-se a uma vedação para vedar entre um eixo rotativo (1) e um alojamento (2). A vedação possui um estator (10) e um rotor (50) acoplados magnética e mecanicamente. O acoplamento mecânico é proporcionado através de uma ranhura anular de intertravamento (54) proporcionada sobre um componente e uma face de flange (21) sobre o outro componente. O acoplamento mecânico permite aos dois componentes se tornarem interconectados após uma faixa pré-determinada de movimento livre do rotor (50) ser excedida. O estator (10) e o rotor (50) também são mecanicamente acoplados através de uma pluralidade de magnetos (61) posicionados ou sobre o estator (10) ou sobre o rotor (50). Após a faixa pré-determinada ser excedida, o rotor (50) desliza ao longo do eixo enquanto o estator (10) permanece fixo, mantendo uma vedação durante o movimento axial do eixo rotativo.
