Abstract (en)

[origin: US4769831A] A rotating anode x-ray tube has an anode magnetically seated in a housing in non-contacting fashion. For non-contacting transmission and dissipation of the anode current, a hollow cylindrical rotor of the anode is provided with ribs on its interior surface. A stationary hollow cylinder is disposed inside of the rotor, the stationary hollow cylinder being also provided with ribs in registry with the ribs on the interior of the rotor, and being connected to the anode lead. Current is thereby transferred from the stationary cylinder to the rotating hollow cylinder by corona discharge.

Abstract (de)

Die Erfindung betrifft eine Drehanoden-Röntgenröhre mit einer magnetisch berührungsfrei gelagerten Anode (2). Zur kontaktlosen Übertragung des Anodenstromes ist der hohlzylindrische Rotor (6) der Anode (2) auf seiner inneren Mantelfläche mit Rippen (9) versehen. Im Innern des Rotors (6) liegt ein feststehender Hohlzylinder (11), der auf seiner äußeren Mantelfläche mit entsprechenden Rippen (10) versehen und mit der Anodenzuleitung (12) verbunden ist.
