Abstract
DISPOSIçãO DE MANCAL HIDRODINáMICO PARA EIXO ROTATIVO E BOMBA Uma disposição de mancal hidrodinâmico (10) para uni eixo rotativo (12), a disposição (10) incluindo um alojamento (14) no qual é previsto um suporte de eixo (16) com uma abertura través da qual o eixo (12) se estende, havendo um espaço entre o suporte de eixo (16) e o eixo (12), o suporte de eixo (16) incluindo pelo menos uma passagem (22a, 22b) através do mesmo que se estende em geral axialmente ao eixo (12) de um primeiro lado do suporte de eixo (16) até uma câmara (28) prevista no alojamento (14) em um segundo lado do suporte de eixo (16), de modo que liquido no primeiro lado do suporte de eixo (16) possa comunicar com a câmara (28) no segundo lado do suporte de eixo (16) e, dessa forma, passe para o espaço entre o eixo (12) e o suporte de eixo (16) tanto a partir do primeiro lado do suporte de eixo (16) quanto a partir do segundo lado do suporte de eixo (16) via passagem (22a, 22b) e câmara (28), o liquido entre o eixo (12) e o suporte de eixo (16) mantendo o espaço entre o eixo (12) e o suporte de eixo (16) e proporcionando um mancal hidrodinâmico para o eixo (12)
