    Abstract: The invention relates to a rotary-anode X-ray tube which includes a sleeve bearing having an axial bearing section and a radial bearing section. Furthermore, radial sealing sections (601, 602) are provided in an outer bearing member (605, 607, 608) which have no functional relation to the axial bearing surfaces (2012) of the axial bearing section. Thus, additional sealing principles like gaskets or sealing edges can be used although this may result in degradation of surface parallelism.

    Abstract: An X-ray tube for generating X-radiation includes a rotary structure having a rotating anode, a stationary structure for rotatably supporting the rotary structure, and a hydrodynamic bearing which is arranged between the rotary structure and the stationary structure. The bearing includes a gap between the rotary structure and the stationary structure, a stabilizer configured to stabilize dimensions of the gap with respect to distortions because of thermo-mechanical causes.

    Abstract: A mechanism to which a liquid-repellent structure hard to be exfoliated is applied.The tip of each of microprojections has a generally spherical surface. When a liquid metal (8) comes into contact with such a surface, the liquid metal (8) cannot enter the spaces among microprojections and is supported by the surfaces of the tips only with point contact.Therefore, the liquid metal (8) neither wets the surface of the base material nor spread over the surface.The liquid-repellent surface (11) has a structure such that the liquid metal (8) is supported by point contact of the many microprojections and repelled by the surface (11), and does not wet the surface (11).

    Abstract: In an X-ray tube, a rotary anode formed into a hollow disk-like shape is fixedly supported by a rotating body formed into a hollow cylindrical shape. A fixed shaft has fixed ends, columnar bearing portions and a disk part, and a flow path of a cooling medium formed along a central axis thereof. The bearing portions are inserted into the rotating body with a first gap between the columnar bearing portion and the rotating body, so that the rotating body is rotatably supported. The disk part is arranged in the rotary anode with a second gap between the disk part and the rotary anode. The first and second gaps are filled with a lubricant, bearing grooves are formed in the bearing portion, thereby forming dynamic pressure bearings, and a center of gravity of the rotary anode is arranged between the first and second dynamic pressure bearings.

    Abstract: In a rotary anode X-ray tube, a disc portion is fitted into a rotary anode with a first gap therebetween and a fixed shaft is fitted into a rotary shaft to support the anode with a second gap therebetween. The disc portion and the fixed shaft are formed integral with each other to have a hollow portion therein. A cooling liquid is allowed to flow through the hollow portion. A liquid metal is filled in the first and second gaps. Dynamic pressure type bearings is formed in the second gap. A passage is formed to directly communicate the first gap to the second gap, whereby the liquid metal being directly supplied from the second gap to the first gap. Thus, the liquid metal can be fed rapidly and surely into the gap between the anode target and a cooling vessel.

    Abstract: An X-ray tube comprises a substantially cylindrical rotor having an anode target fixed thereto, a substantially columnar stationary shaft coaxially arranged inside the rotor with a bearing gap, a dynamic slide bearing having helical grooves and formed between the rotor and the stationary shaft, and a metal lubricant supplied to the grooves and to the gap. An axial bore is formed in the shaft in a manner to extend in the longitudinal direction of the shaft, and an insertion rod is inserted into the axial bore such that a space extending in the longitudinal direction of the shaft is formed between the inner circumferential surface of the axial bore and the outer circumferential surface of the insertion rod. The space acts as a lubricant reservoir for storing the metal lubricant.
