摘要： @ An evacuated envelope is formed with a portion of larger diameter and tubular portions extending along the axis on both sides of the portion of larger diameter in opposite directions. A target with a rotatable anode is arranged in the portion of larger diameter. A pair of shafts arranged on the tube axis and fixed on both sides of this target are arranged in the tubular portions. Each shaft has at least one flange of insulating material on the side facing the target and on its periphery is provided with a metal tube constituting a rotor of a magnetic bearing. On the outermost side of the tubular portion there are arranged a magnetic field generating device and a magnetic drive device that rotates the rotatable anode target.

摘要： The invention relates to a rotary anode X-ray tube having a sliding bearing and a further bearing system. The further bearing system, preferably a magnetic bearing, is constructed so that it can absorb substantially entirely the axial and radial bearing forces, while the sliding bearing, which is preferably constructed as a spiral groove bearing with liquid metal lubrication, is shaped so that it absorbs the bearing forces only for a small fraction. It therefore has only a low friction, but it permits the supply of the anode current and especially an effective cooling of the anode disk.

摘要： @ 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.

摘要： ) L'invention concerne un tube radiogène à anode tournante, dans lequel la rotation de l'anode (6) s'effectue avec des paliers magnétiques (11-13, 12-14).
L'écoulement du courant anodique, dans le tube (1) selon l'invention, est obtenu sans contact grâce à un dispositif (40) muni d'une anode creuse (17) fixe, dans laquelle est disposée une cathode (16) couplée en rotation à l'anode (6) tournante.
L'anode creuse (17) est associée à des moyens de chauffage (21, 45, 32) et, la cathode (16) est chauffée par rayonnement thermique, à l'intérieur de l'anode creuse (17).-

摘要： An evacuated casing (2) has outer and inner tubes (2a, 2b) respectively covering the outer and inner peripheries of a hollow cylindrical rotor (6). Ring members (8a, 8b) of a ferromagnetic material are provided in the inner wall of the rotor (6) and face permanent magnets (12a, 12b), which are provided on the inner periphery of the inner tube (2b) and are magnetized in the radial directions of the rotor (6). The permanent magnets (12a, 12b) are fitted on a cylindrical yoke (10) between first and second poles (10a, 10b, 10c) formed thereon, the fluxes being inserted in the rotor (6) via the inner tube (2b). The first poles (10a, 10c) are disposed to face the respective ring members (8a, 8b) while the second pole (10b) is disposed to face the opposed end faces (8a', 8b') of the ring members (8a, 8b). With this arrangement, contactless magnetic bearings are formed to support the rotor (6) stably.
