Abstract: An x-ray tube has a stationary cathode and a rotating anode in a vacuum housing. The anode is positioned on a housing-fixed axle such that it can be rotated, and is fashioned as a hollow body in the interior of which an axle-fixed ring projection is disposed, such that, at least between an inner surface of the rotating anode and the adjacent outer surface of the ring projection, a gap exists that is filled with liquid metal and forms a liquid-metal fluid bearing for the rotating anode.

Abstract: A high-capacity x-ray tube particularly for use in medical technology in CT apparatuses, has a vacuum housing containing a cathode and a rotatably mounted anode. The anode plate of the anode is connected by a solder connection to the one end of a load-bearing part, the other end of which is attached to the bearing shaft of a drive for placing the anode in rotation. The mechanical strength of the connection location between the anode plate and the load-bearing part is improved by the connection being formed by a positive fit, designed such that the connection surfaces are subjected substantially only to compression given rotation of the anode.

Abstract: A rotating anode for an x-ray tube has an anode body composed of composite fiber material, mounted in a bearing system, the anode body having a target surface with a focal ring and including fibers with particularly high heat conductivity in the longitudinal direction. An axis-proximal cooling system is associated with the anode body. The majority of all fibers with high heat conductivity in the longitudinal direction terminate bluntly both at the focal ring and at the cooling system, such that their abutting faces respectively are in direct, heat-conducting contact both with the focal ring and with the cooling system.

Abstract: An anode target (22) is rotatably supported by a rotating mechanism (25) having a rotary body (23) and a stationary body (28). A fitted portion between the rotary body (23) and the stationary body (28) is formed of bearing areas (L1) to (L4) having dynamic pressure type sliding bearings and a non-bearing area (L5) having a clearance between the rotary body (23) and the stationary body (28) larger than that in the bearing areas (L1) to (L4). The rotary body facing the non-bearing area is positioned where a time for heat transfer from the anode target (22) is shorter than the rotary body facing the bearing areas. Thus, the characteristics of heat radiation from the anode target (22) can be improved, and a stable bearing operation can be maintained.
