Abstract

sistema de suporte de máquina de indução. a presente invenção refere-se a um conjunto de suporte para uma máquina de indução, tal como um motor de corrente alternada, que inclui um suporte magnético para suportar um eixo rotativo. um suporte auxiliar, também suportando o eixo no caso de falha de suporte magnético, é alinhado com a proteção de extremidade de motor e estrutura de modo que as cargas de eixo suportadas pelo mesmo sejam transferidas para a estrutura de forma a reduzir a probabilidade de contato de suporte magnético com o eixo ou sua deformação. o conjunto de suporte pode incorporar elementos de isolamento/amortecimento de vibração e absorção de choque, tal como anéis em o, entre o suporte auxiliar e sua interface de estrutura de suporte para a estrutura. o suporte auxiliar pode ser incorporado em um cartucho removível para facilitar a manutenção da máquina. o conjunto de suporte pode incluir aletas de dissipação de calor.
