Abstract

Bei einem Hydrotransformator in Schrägscheiben- oder Schrägachsen-Bauart mit einer zwischen Rotor und Gehäuse angeordneten Steuerscheibe, die gegenüber dem Gehäuse verdrehbar ist und deren Winkelstellung das Übersetzungsverhältnis des Hydrotransformators bestimmt, wirken auf die Steuerscheibe durch druckbeaufschlagte Dichtflächen hervorgerufenen Kräfte, die - entsprechend der konstruktiven Ausgestaltung des Hydromotors - Reibungsverluste zwischen der Steuerscheibe und dem Rotor oder zwischen der Steuerscheibe und dem Gehäuse verursachen. Um die Reibung und die durch sie verursachten Verluste zu verringern, ist zwischen der Steuerscheibe und dem Gehäuse ein Wälzlager angeordnet, über das sich die Steuerscheibe an dem Gehäuse abstützt. Zur Vereinfachung der Lagerung der Steuerscheibe ist in einer Abschlußplatte des Gehäuses ein Rohr gehalten, das als Achse für die Steuerscheibe dient. Die Erfindung dient zur Verbesserung von Hydrotransformatoren.
