A unitized oil seal assembly (20, 220, 320, 420) has a sealing disk (34, 234, 334, 434) that is split along its outer edge to define a pair of split sections, one of which (48, 248, 348, 438) is fixed to an outer annular carrier member (30, 230, 330, 430) and supports the other split section (50, 250, 350, 450) and an unsplit section (52, 252, 352, 452) in sealing engagement with corresponding sealing surfaces of a wear sleeve (32, 232, 332, 432) to exclude contaminants and retaining lubricant, respectively, from passing by the seal assembly (20, 220, 320, 420).
Selon cette invention, un ensemble intégré (20, 220, 320, 420) de joint étanche à l'huile comprend un disque d'étanchéité (34, 234, 334, 434) qui est fendu le long de son bord externe de manière à délimiter une paire de sections fendues dont l'une (48, 248, 348, 438) est fixée à un élément de support annulaire externe (30, 230, 330, 430) et soutient l'autre section fendue (50, 250, 350, 450) ainsi qu'une section non fendue (52, 252, 352, 452) en les mettant en prise de manière étanche avec les surfaces d'étanchéité correspondantes d'une gaine d'usure (32, 232, 332, 432), et ce de façon à ne pas laisser passer les contaminants et à retenir le lubrifiant, respectivement, de sorte que ce dernier ne s'échappe de l'ensemble intégré (20, 220, 320, 420) de joint étanche à l'huile.
