(FR) AGENCEMENT D'ETANCHEITE ET DE PALIER DANS DES BROSSES A DENTS ELECTRIQUES
Abstract
(EN)
A sealing and bearing arrangement in electric toothbrushes is characterised by a sealing ring (9) for preventing foreign material from penetrating into a bearing space, the ring being arranged around a nose pin (1) in the open end (7) of a casing (5), which coaxially surrounds the nose pin (1), and being immobile when the nose pin (1) rotates; an annular supporting plate (10) which is provided close to and inwardly of the sealing ring (9) and which is immobile when the nose pin (1) rotates; and bearing balls (11) provided in two races, one on each side of a thickened portion (4) of the central member of the nose pin (1), for taking up forces in all directions.
(FR)
Un agencement d'étanchéité et de palier dans des brosses à dent électriques se caractérise par une bague d'étanchéité (9) destinée à empêcher de la matière étrangère de pénétrer dans un espace de palier, ladite bague étant agencée autour d'une tige en pointe (1) située dans l'extrémité (7) d'un logement (5), lequel entoure coaxialement la tige en pointe (1), et est immobile lorsque cette dernière (1) tourne; une plaque de support annulaire (10) laquelle est agencée à proximité et du côté intérieur de ladite bague d'étanchéité (9), et est immobile lorsque ladite tige en pointe tourne; ainsi que des billes de palier (11) disposées sur deux voies, une de chaque côté d'une partie épaissie (4) de l'élément central de ladite tige en pointe (1), destinées à absorber les forces dans tous les sens.
