Title (EN) ROLLING BEARING
(FR) PALIER À ROULEMENT
(DE) WÄLZLAGER
Abstract:
(EN) The invention relates to a rolling bearing, in particular in the form of an open-center large rolling bearing, comprising a large number of rolling elements, which are held between at least two raceways, on which the rolling elements roll, wherein spacers are provided between the rolling elements, which spacers keep the rolling elements spaced apart from each other. According to the invention, at least one of the raceways has, in a center portion, an approximately groove-shaped longitudinal recess, in which support arms provided between the spacers run, which support arms reach around the rolling element between two adjacent spacers and support the adjacent spacers against each other in the running direction of the rolling elements.
(FR) L'invention concerne un palier à roulement, notamment sous la forme d'un palier à roulement de grande dimension à évidement central, comprenant une pluralité de corps roulants qui sont reçus entre au moins deux chemins de roulement, sur lesquels les corps roulants roulent, des éléments d'espacement étant prévus entre les corps roulants, ces éléments maintenant les corps roulants à une certaine distance les uns des autres. Selon l'invention, au moins l'un des chemins de roulement possède, dans une partie centrale, un évidement longitudinal de type rainure dans lequel se déplacent des bras d'appui entre les éléments d'espacement, lesdits bras d'appui entourant respectivement le corps de roulement entre deux éléments d'espacement voisins et soutenant les éléments d'espacement voisins l'un par rapport à l'autre dans le sens de déplacement des corps roulants.
(DE) Wälzlager, insbesondere in Form eines mittenfreien Großwälzlagers, mit einer Vielzahl von Wälzkörpern, die zwischen zumindest zwei Laufbahnen aufgenommen sind, auf denen die Wälzkörper abwälzen, wobei zwischen den Wälzkörpern Distanzhalter vorgesehen sind, die die Wälzkörper voneinander beabstandet halten. Erfindungsgemäß besitzt zumindest eine der Laufbahnen in einem Mittenabschnitt eine etwa nutförmige Längsausnehmung, in der zwischen den Distanzhaltern vorgesehene Stützarme laufen, die jeweils den Wälzkörper zwischen zwei benachbarten Distanzhaltern umgreifen und die benachbarten Distanzhalter gegeneinander in Laufrichtung der Wälzkörper abstützen.
