  • a radial end piece of the radial part of the second ring is provided for axial force transmission to the hollow cylindrical part of the first ring during the press-fitting process.

Abstract

En résumé, l'invention concerne un joint d'étanchéité à cassette pour l'étanchéité d'un palier radial, le joint d'étanchéité à cassette présentant deux bagues mobiles l'une par rapport à l'autre et les deux bagues présentant une partie cylindre creuse et une partie s'étendant dans le sens radial, les parties cylindriques creuses se faisant face radialement et les parties s'étendant radialement se faisant face axialement dans l'état de service. L'objectif est d'améliorer l'efficacité du joint et de permettre en même temps une installation simple des joints d'étanchéité à cassette. Cet objectif est atteint par le fait qu'un rayon extérieur de la partie s'étendant radialement de la seconde bague est plus grand que le rayon intérieur maximum de la partie cylindrique creuse de la première bague et est inférieur au rayon extérieur de la partie cylindrique creuse de la première bague. Ainsi, il est possible de générer avec une dépense de matériau identique un joint à labyrinthe qui protège mieux l'intérieur des joints d'étanchéité à cassette et donc également l'espace de roulement du palier radial vis-à-vis des influences extérieures, telles que humidité et particules de saleté.
