Abstract

1/1 resumo “vedação hidrodinâmica com elemento de vedação de flexibilidade aumentada” um conjunto hidrodinâmico de vedação de eixo inclui um elemento de vedação 5 ptfr (34) que tem seções exterior (36) e interior (38). a seção exterior é fixada a um portador anular (16). a seção interior é livre e inclui pelo menos uma ranhura hidrodinâmica (42) em contato operacional direto com um eixo rotativo ou luva de desgaste. uma porção intermediária (40) do elemento de vedação é formada entre as seções interior e exterior. a porção intermediária é afinada e inclui uma ou mais ondulações anulares (44) formadas nela 10 para melhorar a flexibilidade da seção interior em relação à seção exterior. o conjunto de vedação pode incluir uma ou mais aspectos de exclusão. um invólucro de borracha é moldado ao redor de porções do portador. preferivelmente uma ou mais ondulações anulares (44) são formadas em uma operação de cunhar durante o processo de moldagem da borracha.
