Abstract

VEDAçãO DE EIXO RADIAL COM MúLTIPLOS BORDOS PRé-LUBRIFICADA COM ACOMODAçãO DE GRANDE DESLOCAMENTO RADIAL. A presente invenção refere-se a uma vedação de eixo radial para acomodar o deslocamento radial grande do eixo em relação a um invólucro. A vedação inclui um inserto de retenção anular proporcionado para engatar a vedação com um invólucro fixo. Um corpo de vedação elastomérico anular é moldado junto ao inserto de retenção e inclui uma parte flexível se estendendo axialmente se estendendo a partir de uma superfície interna do inserto de retenção. Uma parte de vedação se estende a partir de uma extremidade radialmente interior da parte flexível e inclui o primeiro e o segundo bordos de vedação e uma superfície de mancal elastomérica disposta entre o primeiro e o segundo bordos de vedação. A superfície de mancal inclui várias almofadas elevadas adaptadas para engatar com o eixo. Cada uma das almofadas inclui uma borda arredondada nas laterais das mesmas para encorajar a criação de uma película de lubrificação entre as almofadas e o eixo. As almofadas são lubrificadas por um lubrificante disposto em uma câmara lubrificante disposta entre o primeiro e o segundo bordos de vedação.
