Abstract
Die Erfindung betrifft ein Wälzlager (50), welches einen Wälzlagerinnenring (51), einen Wälzlageraußenring (52) und einen Wälzlagerkugelkäfigring (53) aufweist. Um beispielsweise für eine Nockenwelle (10), deren Phasenlage gegenüber einer Kurbelwelle mittels eines hydraulischen Druckmittels (P) durch eine hydraulische Phasenstelleinrichtung (20) einstellbar ist, eine möglichst Bauraum sparende Möglichkeit zur Übertragung eines hydraulischen Druckmittels (P) zur Verfügung zu stellen, umfasst das Wälzlager (50) mindestens einen Kanal (51a, 51a', 52a', 41, 42) zur Leitung eines hydraulischen Druckmittels (P). Darüber hinaus betrifft die Erfindung eine mit einem derartigen Wälzlager (50) ausgestattete Nockenwellenbaueinheit.
