Title
(EN) SEAL ASSEMBLY WITH ANTI-ROTATION AND STABILITY FEATURES
(FR) ENSEMBLE JOINT AYANT DES CARACTÉRISTIQUES ANTI-ROTATION ET DE STABILITÉ
Abstract
(EN)
A rotary shaft sealing assembly having a rotatable shaft, a sea! housing having a groove bore located radially outward of and facing the rotatable shaft, and a sealing element in sealing contact with the shaft and groove bore. The sealing element having seal body first and second ends and tangs extending axially from the seal body first end. A shelf member has an outer groove wall and a shelf defining an inner groove wall. The inner and outer groove walls providing axial support to the sealing element in certain conditions of assembly and operation. The seal housing or the shelf member providing restraints, with a portion of the restraints in circumferential alignment with the tangs and blocking rotation of the sealing element. The shelf, located radially between the shaft and the restraints, blocks and prevents loss of the restraints.

La présente invention concerne un ensemble d'étanchéité d'arbre rotatif comprenant un arbre rotatif, un boîtier de joint ayant un alésage de rainure situé radialement vers l'extérieur de l'arbre rotatif et faisant face à celui-ci, et un élément d'étanchéité en contact étanche avec l'arbre et l'alésage de rainure. L'élément d'étanchéité comprend des première et seconde extrémités de corps de joint et des tenons s'étendant axialement à partir de la première extrémité de corps de joint. Un élément d'étagère comporte une paroi de rainure externe et une étagère définissant une paroi de rainure interne. Les parois de rainure interne et externe fournissent un support axial à l'élément d'étanchéité dans certaines conditions d'assemblage et de fonctionnement. Le boîtier de joint ou l'élément d'étagère fournit des dispositifs de retenue, une partie des dispositifs de retenue étant en alignement circonférentiel avec les tenons et bloquant la rotation de l'élément d'étanchéité. L'étagère, située radialement entre l'arbre et les dispositifs de retenue, bloque et empêche la perte des dispositifs de retenue.
