    Abstract: A rotating anode bearing housing includes an x-ray tube frame (106) that has a vacuum chamber (108). An anode (110) resides within the vacuum chamber (108) and rotates on a shaft (114) via a bearing (117). The bearing (117) is attached to an interior surface (126) of the x-ray tube frame (106). The bearing (117) transfers thermal energy from the shaft (114) to the x-ray tube frame (106).

    Abstract: To reduce the rotational power, an apparatus with a rotational body that is rotationally driven in a fluid-filled housing a rotational directing body is provided between the rotational body and the housing, which is rotatably supported coaxially with respect to the rotational body. The rotational directing body is configured such that in operation it rotates at an intermediate rotational frequency in comparison to the housing and the rotational body. The apparatus is particularly an X-ray radiator having a cathode and anode that are mounted in a vacuum tube in a spatially fixed manner in relation to the tube, the vacuum tube being rotationally driven as a rotational body in a coolant housing.

    Abstract: An X-ray tube comprises a cathode, an anode target assembly and an axial flux motor having a rotor and a stator. The stator is positioned along a transverse axis parallel to the rotor axis. The rotor and the stator are configured to be coupled to the anode target assembly. A cathode generates an electron beam for impingement upon the anode target assembly and a vacuum housing surrounds the anode target assembly, the cathode and the rotor to enable the electron beam impingement.

    Abstract: An x-ray tube is disposed within an x-ray tube housing defining a chamber filled with oil or other cooling medium for cooling the x-ray tube. The x-ray tube includes an envelope enclosing an evacuated chamber in which an anode assembly is rotatably mounted to a bearing assembly and interacts with a cathode assembly for production of x-rays. The bearing assembly includes a bearing housing and a plurality of bearings disposed on a surface of the bearing housing. A heat sink is coupled to the bearing assembly and provides a thermally conductive path between the bearing assembly and the cooling medium in the x-ray tube housing for providing direct cooling of the bearing assembly during operation.

    Abstract: An anode of a rotary-anode X-ray tube is connected to a bearing portion which is rotatable about an axis of rotation and which cooperates with the stationary bearing portion in which there is provided a cavity which extends in the direction of the axis of rotation and whose side walls can be cooled by means of a cooling medium. Effective cooling, in combination with a small pressure drop of the cooling medium, is achieved in that there is provided a cooling member which serves to produce an essentially laminar cooling medium flow and which consists of a number of lamellae which extend essentially parallel to the axis and which are in thermal contact with the side walls of the cavity.
