Title
(DE) WÄLZLAGER-DREHVERBINDUNG
(EN) ANTI-FRICTION BEARING REVOLVING JOINT
(FR) CONNEXION ROTATIVE DE PALIER À ROULEMENT
Abstract
(DE)
Die Erfindung betrifft eine Wälzlager-Drehverbindung (1), bestehend aus zwei konzentrisch um eine Lagerachse (4) ineinander angeordneten Tragringen (2, 3), die zwischen sich ein Wälzlager aufnehmen, dessen Wälzkörper auf zugehörigen Laufbahnen spanlos geformter, von den Tragringen (2, 3) aufgenommener Lagerschalen abrollen, wobei ein Tragring (2, 3) zweiteilig ausgebildet ist. Erfindungsgemäß ist das Wälzlager als ein doppelreihiges Schrägkugellager (5) ausgebildet, dessen Lagerkugeln (6, 7) zueinander in O-Anordnung angestellt sind.
(EN)
The invention relates to an anti-friction bearing revolving joint (1), consisting of two bearer rings (2, 3) which are arranged one inside the other concentrically about a bearing axis (4) and, between them, receive an anti-friction bearing, the anti-friction elements of said anti-friction bearing rolling on associated raceways of bearing shells which are shaped without cutting and are held by the bearer rings (2, 3), wherein one bearer ring (2, 3) has a two-part design. According to the invention, the anti-friction bearing is designed as a double-row angular-contact ball bearing (5), the bearing balls (6, 7) thereof being positioned in an O arrangement with respect to one another.
(FR)
L'invention concerne une connexion rotative de palier à roulement (1) composée de deux bagues porteuses (2, 3) disposées l'une dans l'autre de façon concentrique autour d'un axe de palier (4), un palier à roulement étant reçu entre les bagues porteuses. Les corps de roulement du palier roulent sur des voies de roulement correspondantes de coquilles de palier formées sans enlèvement de copeaux, reçues par les bagues porteuses (2, 3), une bague porteuse (2, 3) étant conçue en deux parties. Selon l'invention, le palier à roulement est conçu en tant que roulement à billes à portée oblique à double rangée (5), dont les billes (6, 7) sont disposées en O les unes par rapport aux autres.
