Title (EN) SEALED CRUSHER
(FR) CONCASSEUR ETANCHEIFIE
Abstract:
(EN) A gyratory crusher having a frame (1) and in the frame an eccentric shaft (3) rotatable around a vertical shaft in the frame, with a vertical inclined hole in it. A main shaft (4) is supported by bearings in the hole of the eccentric shaft, a supporting cone (5) being attached to the upper end of said main shaft (4). Around the main shaft, below the supporting cone (5) there is a sealing cover (10) covering the eccentric shaft. The upper edge (12) of the sealing cover (10) is sealed against the main shaft (4) by means of a sealing member (13), the outer edge of which has been fitted in an annular groove (17) on the inner edge (12) of the sealing cover (10). The face-to-face arranged upper and lower surfaces of the part (13'') of the sealing member (13) in the groove and the groove (17) of the sealing cover (10) are inclined so that their outer edges are higher up than their inner edges.
(FR) Concasseur giratoire comportant un cadre (1) dans lequel un arbre excentrique (3) peut tourner autour d'un arbre vertical, un trou vertical incliné étant ménagé dans cet arbre excentrique. Un arbre principal (4) est supporté par des paliers situés dans le trou de l'arbre excentrique, un cône support étant fixé à l'extrémité supérieure de l'arbre principal (4). Ménagé autour de l'arbre principal, sous le cône support (5), un couvercle d'étanchéité (10) recouvre l'arbre d'excentrique. Le bord supérieur (12) du couvercle d'étanchéité est scellé contre l'arbre principal (4) au moyen d'un élément d'étanchéité (13), dont le bord externe a été adapté dans une rainure annulaire (17) du bord interne (12) du couvercle d'étanchéité (10). Les surfaces supérieure et inférieure opposées de la partie (13'') de l'élément d'étanchéité (13) de la rainure et la rainure (17) du couvercle d'étanchéité (10) sont inclinées de façon à ce que leurs bords externes soient plus hauts que leurs bords internes.
