Patent

CA 2333480

The invention relates to a roller arrangement for a product to be coated in a molten metal bath, comprising a roller (1) which rotates in said molten metal bath and which is supported at the end on support arms (2) by rolling bearings (4), in such a way that it can still rotate. Said rolling bearings (4) are each located in a bearing housing (5) which is sealed tightly against the molten metal bath (M). The inventive roller arrangement is characterised in that sealing surfaces (15, 16) are provided on the bearing housing in order to tightly seal said bearing housing (5) against the roller (1). Said sealing surface extend crosswise to the roller axle (X) and are held together or on an intermediate sealing element (20) under pressure.

L'invention concerne un système de rouleau pour produit à revêtir dans un bain métallique liquide, comportant un rouleau (1) tournant dans le bain métallique, qui est maintenu côté extrémité sur des bras porteurs (2) par des paliers à roulement (4) de manière à pouvoir tourner, ces paliers à roulement (4) étant disposés respectivement dans un logement de palier (5) rendu étanche par rapport au bain métallique (M). Le système de rouleau est caractérisé en ce que pour rendre étanche le logement de palier (5) sont formées des surfaces d'étanchéité (15, 16) s'étendant contre le rouleau (1) et au niveau du logement de palier (5), perpendiculairement par rapport à l'axe de rouleau (X), ces surfaces d'étanchéité étant maintenues sous pression l'une contre l'autre ou bien contre un élément d'étanchéité (20) intercalé.
