Abstract

Dispositif d'étanchéité pour un palier anti-friction. Le dispositif d'étanchéité selon la présente invention comporte une bague intérieure 1 dont l'épaulement est muni d'une partie périphérique étagée 2 comportant une surface périphérique 2a inclinée axialement vers l'intérieur de la bague intérieure et un organe d'étanchéité annulaire 5 renforcé par un noyau métallique et muni sur son pourtour intérieur d'une lèvre d'etanchéité 6 allongée et flexible s'étendant dans le sens radial le long de la paroi latérale de la partie étagée, un léger intervalle S3 étant formé entre la lèvre d'étanchéité et cette paroi latérale. Un prolongement annulaire 8 en contact léger avec la paroi latérale de la portion étagée de la bague est prévu sur la partie périphérique intérieure de cet organe d'étanchéité annulaire qui présente également une surface périphérique intérieure inclinée 6a délimitant un faible intervalle S1 entre cette surface périphérique intérieure et la surface périphérique 2a formant le fond de la partie étagée. Application à des palmiers à roulements présentant des caractéristiques d'étanchéité à la poussière, d'étanchéité aux fuites de lubrifiant et des performances en rotation améliorées.Sealing device for an anti-friction bearing. The sealing device according to the present invention comprises an inner ring 1, the shoulder of which is provided with a stepped peripheral part 2 comprising a peripheral surface 2a inclined axially towards the inside of the inner ring and an annular sealing member 5. reinforced by a metal core and provided on its inner periphery with an elongated and flexible sealing lip 6 extending radially along the side wall of the stepped part, a slight gap S3 being formed between the lip d sealing and this side wall. An annular extension 8 in light contact with the side wall of the stepped portion of the ring is provided on the inner peripheral part of this annular sealing member which also has an inclined inner peripheral surface 6a defining a small gap S1 between this peripheral surface interior and the peripheral surface 2a forming the bottom of the stepped part. Application to rolling palms having characteristics of dust tightness, lubricant leak tightness and improved rotational performance.
