Abstract

Abstract Translated from German @ Die Erfindung betrifft eine Drehanoden-Röntgenröhre mit einem Gleitlager und einem weiteren Lagersystem. Das weitere Lagersystem, vorzugsweise ein Magnetlager, ist dabei so ausgelegt, daß es praktisch die gesamten axialen und radialen Lagerkräfte vollständig aufnehmen kann, während das vorzugsweise als Spiralrillenlager mit Flüssigmetallschmierung ausgebildete Gleitlager so gestaltet ist, daß es die Lagerkräfte nur zu eiem geringen Bruchteil aufnimmt. Es hat daher nur eine geringe Reibung, gestattet aber die Zufuhr des Anodenstroms und vor allem eine wirksame Kühlung der Anodenscheibe. @ The invention relates to a rotating anode X-ray tube with a plain bearing and another bearing system. The further bearing system, preferably a magnetic bearing, is designed so that it can absorb virtually all of the axial and radial bearing forces, while the slide bearing, which is preferably designed as a spiral groove bearing with liquid metal lubrication, is designed in such a way that it absorbs the bearing forces only to a small fraction. It therefore has little friction, but allows the anode current to be supplied and, above all, effective cooling of the anode disk.
