Title
(DE) WÄLZLAGER MIT EINEM DIREKTANTRIEB
(EN) ROLLING-ELEMENT BEARING HAVING A DIRECT DRIVE
(FR) PALIER À ROULEMENT À ENTRAÎNEMENT DIRECT
Abstract
(DE)
Die Erfindung betrifft ein Wälzlager mit einer Direktantriebseinheit und ein Lagerring eines Wälzlagers. Das Wälzlager umfasst einen stehenden Lagerring (01), welcher mit mindestens einem Primärteil (07) der Direktantriebseinheit verbunden ist, einen als Sekundärteil ausgebildeten gegenüber dem stehenden Lagerring (01) drehbaren Lagerring (02) und Wälzkörper (04), die zwischen dem stehenden und dem rotierenden Lagerring angeordnet sind. Erfindungsgemäß ist der drehbare Lagerring (02) mit Rotorpolen (06) versehen ist. Das Primärteil umfasst eine Statorwicklung (10) und überdeckt zumindest abschnittsweise die Rotorpole (06) des rotierenden Lagerringes (02).
(EN)
The invention relates to a rolling-element bearing having a direct drive unit and to a bearing ring of a rolling-element bearing. The rolling-element bearing comprises a stationary bearing ring (01) which is connected to at least one primary part (07) of the direct drive unit, a bearing ring (02) that is designed as a secondary part and that can be rotated relative to the stationary bearing ring (01), and rolling elements (04), which are arranged between the stationary bearing ring and the rotating bearing ring. According to the invention, the rotatable bearing ring (02) is provided with rotor poles (06). The primary part comprises a stator winding (10) and covers the rotor poles (06) of the rotating bearing ring (02) at least in some sections.
(FR)
L'invention concerne un palier à roulement équipé d'un ensemble d'entraînement direct, ainsi qu'une bague de palier d'un palier à roulement. Le palier à roulement comprend une bague de palier fixe (01) reliée à au moins une partie primaire (07) de l'ensemble d'entraînement direct, une bague de palier rotative (02) par rapport à la bague de palier fixe (01) réalisée en tant que partie secondaire, et des corps de roulement (04) disposés entre la bague de palier fixe et la bague de palier rotative. Selon l'invention, la bague de palier rotative (02) est munie de pôles de rotor (06). La partie primaire comprend un enroulement de stator (10) et recouvre au moins par endroits les pôles de rotor (06) de la bague de palier rotative (02).
