Title
(DE) KÄFIGLOSES WÄLZLAGER
(EN) CAGE-FREE ROLLING BEARING
(FR) PALIER À ROULEMENTS SANS CAGE
Abstract
(DE)
Die Erfindung betrifft ein käfigloses Wälzlager (1) mit einer Mehrzahl von Wälzkörpern (4), welche zwischen einem Innenring (2) und einem konzentrisch zum Innenring (2) angeordneten Außenring (3) in Umfangsrichtung verteilt angeordnet sind; und einem Andrückelement (6), welches ringsegmentartig entlang der Umfangsrichtung angeordnet ist, zumindest zeitweise mindestens zwei der Wälzkörper (4) gleichzeitig kontaktiert, und jeden der kontaktierten Wälzkörper (4) mit einer in axiale Richtung orientierten Kraft beaufschlagt.
(EN)
The invention relates to a cage-free rolling bearing (1) having a plurality of rolling elements (4) which are arranged so as to be distributed in the circumferential direction between an inner ring (2) and an outer ring (3) that is arranged concentrically to the inner ring (2); and a pressing element (6) which is arranged in the manner of a ring segment along the circumferential direction, at least temporarily contacts at least two of the rolling elements (4) simultaneously, and applies a force oriented in an axial direction to each of the contacted rolling elements (4).
(FR)
L’invention concerne un palier à roulements sans cage (1) comprenant une pluralité de corps de roulement (4) qui sont répartis dans la direction circonférentielle entre un anneau interne (2) et un anneau externe (3) disposé de façon concentrique par rapport à l’anneau interne (2) ; et un élément de pression (6) qui est disposé sous forme de segment annulaire le long de la direction circonférentielle, est au moins temporairement en contact simultané avec au moins deux des corps de roulement (4), et sollicite chacun des corps de roulement (4) mis en contact avec une force orientée dans la direction axiale.
