Abstract

L’invention concerne un dispositif d’étanchéité (6) comprenant une première armature (7) et une deuxième armature (8) formant un passage (9) entre une interface de rotation (3) et l’extérieur, l’armature (7) présentant une géométrie en U couché formée d’une paroi centrale (7a) radiale et bordée de part et d’autre par deux parois périphériques (7b, 7c) axiales, l'armature (8) présentant un fond (8a) axiale et deux parois latérales (8b, 8c) radiales respectivement d’un côté dudit fond afin de délimiter une cuvette (10) entre eux, l’armature (8) présentant en outre une paroi extérieure (8d) axiale, en étant reliée d’une part à une paroi (8b, 8c) et en formant d’autre part avec l’autre paroi (8b, 8c) une ouverture (11) pour le passage (9), dans laquelle l’une des parois (7b, 7c) s’étend pour former une chicane le long dudit passage. Figure 1aThe invention relates to a sealing device (6) comprising a first armature (7) and a second armature (8) forming a passage (9) between a rotation interface (3) and the outside, the armature (7 ) having a recumbent U-shaped geometry formed of a radial central wall (7a) and bordered on either side by two axial peripheral walls (7b, 7c), the armature (8) having an axial bottom (8a) and two radial side walls (8b, 8c) respectively on one side of said bottom in order to delimit a basin (10) between them, the frame (8) further having an axial outer wall (8d), being connected by a part to one wall (8b, 8c) and on the other hand forming with the other wall (8b, 8c) an opening (11) for the passage (9), in which one of the walls (7b, 7c) extends to form a baffle along said passage.
