Abstract

L’invention concerne un ensemble palier et joint d’étanchéité (10) pour un arbre (1), l’arbre (1) étant rotatif autour d’un axe central (Ac). L’ensemble (10) comprend un corps intérieur globalement tubulaire (12) pouvant être disposé autour de l’arbre (1) et accouplé à celui-ci de façon à être rotatif autour de l’axe central (Ac) et comportant une bague de palier intérieure (13), et une surface d’interaction (15) avec le joint d’étanchéité (20). L’ensemble (10) comprend également un corps extérieur globalement tubulaire (14) disposé de manière globalement coaxiale autour du corps intérieur (12), et comportant une bague extérieure de palier (17). Une pluralité de corps roulants (16) est disposée entre la bague intérieure (13) du corps intérieur (12) et la bague extérieure (17) du corps extérieur (14) de façon à former un palier (18). Au moins un élément (50) formant le joint d’étanchéité (20) globalement annulaire est disposé entre les corps intérieur et extérieur (12, 14) et espacé axialement vis-à-vis du palier (18), le ou les éléments (50) formant le joint d’étanchéité (20) formant une surface d’étanchéité circonférentielle intérieure (54) pouvant interagir à étanchéité avec la surface d’interaction (15) lorsque le corps intérieur (12) est globalement stationnaire par rapport à l’axe central (Ac), le joint d’étanchéité (20) étant configuré pour se déplacer globalement radialement vers l’extérieur de façon à être espacé vis-à-vis de la surface d’interaction (15) lorsque le corps intérieur (12) tourne autour de l’axe central (Ac). Figure 1The invention relates to a bearing and seal assembly (10) for a shaft (1), the shaft (1) being rotatable about a central axis (Ac). The assembly (10) comprises a generally tubular inner body (12) which can be arranged around the shaft (1) and coupled to the latter so as to be rotatable around the central axis (Ac) and comprising a ring inner bearing (13), and an interaction surface (15) with the seal (20). The assembly (10) also includes a generally tubular outer body (14) disposed generally coaxially around the inner body (12), and comprising an outer bearing ring (17). A plurality of rolling bodies (16) is disposed between the inner ring (13) of the inner body (12) and the outer ring (17) of the outer body (14) so as to form a bearing (18). At least one element (50) forming the generally annular seal (20) is disposed between the interior and exterior bodies (12, 14) and axially spaced apart from the bearing (18), the element (s) ( 50) forming the seal (20) forming an inner circumferential sealing surface (54) capable of interacting sealingly with the interaction surface (15) when the inner body (12) is generally stationary relative to the central axis (Ac), the seal (20) being configured to move generally radially outward so as to be spaced from the interaction surface (15) when the inner body (12 ) rotates around the central axis (Ac).
