Abstract: A structure and associated method for forming a liquid metal or spiral groove bearing assembly for an x-ray tube is illustrated that utilizes a unitary sleeve and a thrust ring or seal each formed of a weldable, non-refractory material. The sleeve and the thrust seal are welded to one another to provide an improved construction for minimizing leaks of the liquid metal bearing fluid. The structure of the sleeve and the thrust seal are formed with deformation restricting features that maintain the integrity of the bearing surfaces of the assembly when the thrust seal is secured within the sleeve and welded thereto to form the bearing assembly.

The rotary anode and the rotor have a torque-proof connection to one another and are rotatably supported in the vacuum container, so that the rotary anode and the rotor are rotatable around an axis of rotation. Viewed in a direction of the axis of rotation, a laminated stator core is disposed in an area of the rotor. The area of the rotor, in relation to the axis of rotation, surrounds the vacuum container radially outwards. A stator winding system is disposed in the laminated stator core. The stator winding system has windings embodied as a yoke winding.
