The lift shaft may be coupled to the anode and configured to rotate around an axis of rotation of the anode. The lift electromagnet may be configured to apply a magnetic force to the lift shaft in a radial direction. The lift electromagnet may include a curved surface that contours around at least a portion of the shaft wall. A radius of curvature of the curved surface of the lift electromagnet may be greater than a radius of curvature of the lift shaft, and the spacing between the curved surface of the lift electromagnet and the shaft wall may be non-uniform.

In order to provide improved balancing for a minimized imbalance during operation, an X-ray tube (10) with an active balancing arrangement (12) is provided, comprising a rotating anode arrangement (14), a bearing arrangement (20, 22, 24), a driving arrangement (26, 28, 30) for rotating the anode arrangement, an imbalance detection arrangement (32), and active balancing means (34, 36, 38, 40, 42). The bearing arrangement is provided as a fixed bearing of the rotating anode arrangement for supporting the rotating anode arrangement. The imbalance detection arrangement is configured to detect an imbalance of the anode. The active balancing means are electro-magnetic balancing means configured to provide a magnetic field and to apply magnetic eccentricity forces to the rotating arrangement.

摘要： 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.

摘要： In exemplary embodiments, the anode is driven by an induction motor, between the stator and rotor of which the wall of the vacuum envelope of the tube is disposed. To reduce the overall length and the lever actions of the weight of the anode which act on the bearing which are disadvantageous in this construction, the disclosure provides an annular anode which is disposed in the same plane with the drive rotor. The rotor and stator can here be surrounded by the ring of the anode or they can be secured externally about the latter. X-ray tubes in accordance with the disclosure are particularly suited for use for the purpose of medical x-ray examination.
