Abstract

vedação de eixo de torção inferior com articulação de ligação de elemento de vedação aprimorada. uma montagem de vedação de eixo (10) inclui uma capa de metal (12) com uma parede (14) que se estende de modo cilíndrico ao redor de um eixo geométrico central (16) com uma perna anular (18) que se estende de modo radial para dentro a partir da parede (14) na direção do eixo geométrico central (16). um material elastomérico (20) é ligado à perna (18), e um elemento de vedação de ptfe (22) é fixado ao material elastomérico (20) em uma articulação de ligação. a articulação de ligação é espaçada de modo radial para dentro a partir da perna (18) e em alinhamento radial à perna (18) e inibe que o material elastomérico (20) se flexione. assim, o material elastomérico (20) é isolado ou substancialmente isolado de impactar o desempenho do elemento de vedação de ptfe (22) durante o uso. portanto, a articulação de ligação fornece uma vedação confiável do elemento de vedação de ptfe (22) contra uma superfície corrediça de um eixo ou manga gasta.
