Abstract

disposição de vedação para rolamentos a invenção se refere, sumariamente, a uma disposição de vedação para vedar um rolamento, em especial, um rolamento de roda, entre um primeiro componente do rolamento (30, 32) e um segundo componente do rolamento (32), sendo que ambos os componentes do rolamento são rotacionáveis em em relação ao outro e formam intermediário axial (61) como um espaço intermediário radial (60) em relação a um eixo de rotação comum, sendo que a disposição de vedação abrange o seguinte: um componente de contato (14, 24) com uma peça de fixação e uma peça de contato (41, 43), em formato anular, para posicionar o componente de contato (14, 24) no segundo componente do rolamento, e um suporte (39, 45) que pode ser fixado no primeiro componente do rolamento (30, 32) com uma peça elástica (13, 23) que forma um um primeiro lábio de vedação lábio de vedação axial (17, 29) e/ou um segundo lábio de vedação radial (19, 36). a instrução de acordo com a invenção mostra como a vida útil e a vedação podem ser aumentadas de maneiras econômica. é proposto que o componente de contato (14, 24) forme uma primeira ranhura de coleta (12, 22) com uma parte do segundo componente do rolamento (31), que se estende radialmente, sendo que uma peça de extremidade (34, 44) do componente de contato limita parcialmente uma abertura (50, 51) que desemboca na primeira ranhura de coleta (12, 22). com isso, é possível se estabelecer uma vedação labiríntica como uma pré-vedação, que colabora efetivamente na vedação, sem perdas adicionais por atrito.
