    Abstract: An x-ray device has a cathode aligned on a target region in a tube housing with a rotating anode unit. The rotating anode unit is borne to rotate around a rotational axis inside the tube housing. The rotating anode unit has a rotating anode plate with the target region and a shaft rotationally connected with the rotating anode plate. A magnetic bearing supports the shaft without contact in the tube housing. The rotating anode plate has an axial extension facing away from the shaft. The axial extension dips into a fluid-filled receptacle space of the tube housing for heat dissipation. Such an x-ray device allows high rotation speeds of the rotating anode unit, and thus a high operational power.

    Abstract: An electromagnetic bearing wherein a group of magnetic poles is formed on each end of a columnar yoke. The magnetic pole groups each include four magnetic poles which protrude from the center of the yoke at right angles to one another and to the longitudinal direction of the yoke. A cylindrical supported body surrounds the yoke and the magnetic poles. A ring-shaped member formed of a ferromagnetic material is fixed to the inner peripheral surface of the supported body so that both end portions of the ring-shaped member are in alignment with the centers of their corresponding magnetic poles of the magnetic pole groups. Magnetic fluxes delivered from each aligned pair of magnetic poles enter the ring-shaped member substantially at right angles to the peripheral surface thereof, and return to those original magnetic poles via another pair of magnetic poles adjacent thereto. Thus, the supported body is supported in its radial direction. Magnetic fluxes pass through the yoke along its longitudinal direction, enter one end face of the ring-shaped member at right angles thereto via the magnetic poles of the first magnetic pole group, pass through the ring-shaped member along its longitudinal direction, and enter the magnetic poles of the second magnetic pole group via the other end face of the ring-shaped member. Thus, the supported body is supported in its longitudinal direction.

    Abstract: In the case of tubes with magnetically mounted anodes, it is difficult to obtain an adequately stable mounting of the anode shaft for all stresses to be expected, in particular, in the case of tilting and pivoting. To this end, the disclosure provides that magnetically conductive pole pieces are inserted in the wall of the tube envelope at the locations at which magnets are exteriorly disposed which pole pieces are in magnetic coupling relation with the anode arrangement. The distances between the parts to be magnetically coupled can thereby be substantially reduced, so that there results--in relation to known magnetic bearings--a substantially more stable support-mounting of the rotary anode in the high vacuum envelope. The disclosure is, in particular, applicable in the case of X-ray tubes for utilization in medical X-ray technology.

    Abstract: The invention relates to an X-ray tube. The tube has a rotary anode which is rotatably journalled by means of a magnetic bearing having a stator comprising a magnet yoke which intersects the outer walls of the tube and which is magnetizable by magnets arranged outside the tube. The magnet yoke comprises radially extending pole faces which enclose gaps in conjunction with radially extending pole faces of a rotor connected to the rotary anode. The rotor consists of a soft-magnetic disk, which provides the magnet yoke which closes the magnet yoke of the stator.
