Abstract
(DE)
Es wird ein Wälzlager (1) mit einer Dichtungsanordnung (2), vorzugsweise als Kompaktlager und Abdichtung für Wasserpumpen, mit zwei axial benachbarten W älzkörperreihen (14, 15) zwischen einem Außenring (10) und einem W ellenlagerabschnitt (31), sowie einer nassseitigen W ellendichtung (24) und einer trockenseitigen Wellendichtung (25) vorgeschlagen. Ein Schmierstoffdepot (20) mit einem zumindest bereichsweise porösen Substrat (21) ist umlaufend in einem radialen Kontakt zu dem Wellenabschnitt (31) und dem Außenring (10) angeordnet; wobei das Schmierstoffdepot (20) in Poren des Substrats (21) einen wasserunlöslichen Schmierstoff enthält, und ein Volumen des Schmierstoffdepots (20) und ein Volumen einer Schmierstofffüllung (22) mit dem Schmierstoff ein Gesamtvolumen von Freiräumen zwischen der nassseitigen Wellendichtung (24) und der trockenseitigen Wellendichtung (25) einnehmen.
(EN)
The invention relates to a rolling bearing (1) comprising a sealing assembly (2), preferably in the form of a compact bearing and seal for water pumps, comprising two axially neighbouring rolling element rows (14, 15) between an outer ring (10) and a shaft bearing section (31), as well as a wet-side shaft seal (24) and a dry-side shaft seal (25). A lubricant depot (20) having a substrate (21) that is porous at least in regions, is arranged such that it is peripherally in radial contact with the shaft section (31) and the outer ring (10), wherein the lubricant depot (20) contains a water-insoluble lubricant in the pores of the substrate (21), and a volume of the lubricant depot (20) and a volume of a lubricant supply (22) with the lubricant take up a total volume of free space between the wet-side shaft seal (24) and the dry-side shaft seal (25).
(FR)
L’invention concerne un palier à roulement (1) doté d’un système d’étanchéité (2), se présentant de préférence sous forme de palier compact et de garniture d’étanchéité pour des pompes à eau, qui comprend deux rangées de corps de roulement (14, 15) situées à proximité l’une de l’autre dans le sens axial, entre une bague extérieure (10) et une partie de palier d’arbre (31), ainsi qu’une garniture d’étanchéité d’arbre (24), côté face humide, et une garniture d’étanchéité d’arbre (25), côté face sèche. Un dépôt de lubrifiant (20) muni d’un substrat (21), poreux au moins par endroits, est agencé en périphérie en un contact radial avec la partie d’arbre (31) et la bague extérieure (10); ledit dépôt de lubrifiant (20) contenant dans des pores du substrat (21) un lubrifiant non soluble dans l’eau, et un volume de dépôt de lubrifiant (20) et un volume d’une charge de lubrifiant (22) occupant avec le lubrifiant un volume total d’espaces libres entre la garniture d’étanchéité d’arbre (24), côté face humide, et la garniture d’étanchéité d’arbre (25), côté face sèche.
