Abstract

resumo patente de invenção: "dispositivo de mancal axial tendo enchimento de ferro aumentado". o objetivo da invenção é proporcionar um dispositivo de mancal axial tendo densidade de força aumentada e uma construção simples. o referido objetivo é alcançado por um dispositivo de mancal axial tendo uma disposição de folha elétrica anular, em que as folhas individuais (80, 90, 170) se projetam radialmente para fora. além disso, uma bobina elétrica é proporcionada no dispositivo de mancal axial e é inserida na disposição de folha elétrica para gerar um campo magnético na disposição de folha elétrica. a referida disposição compreende pelo menos dois anéis de folha elétrica concêntricos (8, 9, 17). todas as folhas elétricas adjacentes (80, 90, 170) de cada anel de folha elétrica (8, 9, 17). todas as folhas elétricas adjacentes (80, 90, 170) de cada anel de folha elétrica (8, 9, 17) se apoiam, substanci-almente, na circunferência interna (14, 18, 19) do respectivo anel de folha elétrica. a referida laminação (12) resulta em enchimento de ferro aumentado em relação à laminação convencional (11).
