摘要： 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.

摘要： An X-ray tube equipped with a rotating anode cartridge comprising a reinforced sealing system. This sealing system is achieved in three complementary manners. Firstly, when the anode rotates, in order to confine the liquid alloy within the cartridge, the invention provides to equip the two surfaces of a leak-tight joint with grooves thereby obtaining a double sided joint with an improved efficiency. Secondly, the double sided joint makes it possible to obtain, for the vacuum tightness, when the anode shaft is not rotating, two spaces limited by the surface tension of the alloy of liquid metal. The more symmetrical these two spaces, the more the sealing is reinforced. Thirdly, the invention provides to separate the ring from the axis of rotation. This enables a joint centering the two spaces in an automatic and natural manner to be obtained.

摘要： A method for manufacturing an x-ray tube bearing cage includes the step of forming a bearing cage from a carbon-carbon composite material. A coating is applied to the carbon-carbon composite bearing cage. The coating includes an outer layer formed of a dry film lubricant. The coated carbon-carbon composite bearing cage is included in a bearing assembly in the x-ray tube and forms a lubricious enclosure for bearing balls positioned therein to minimize wear and heat generation in the bearing assembly.

摘要： A system for mitigating a gas load imposed upon a high vacuum chamber, thereby reducing the overall pressure, includes a device mounted onto a rotating gantry. The device has a first chamber enclosing a high vacuum and a first region in which anode bearings are positioned. A rotatable shaft has a first portion extending into the first chamber and a second portion extending into the first region. A ferrofluid seal is positioned about the rotatable shaft and positioned between the first portion and the second portion, the ferrofluid seal fluidically separating the first chamber from the first region. At least one pressure-reducing unit is fluidically connected to the first chamber.

摘要： A rotating anode is mounted on a shaft of an X-ray tube by means of a ring. The ring allows expansion and reduces the hyperstatic state of the assembly. The ring has the shape of a diabolo, preferably that of a hyperboloid structure generated by revolution. The ring dampens vibration phenomena in a shaft bearing the rotating anode and reduces noise-creating phenomena.

摘要： In a rotary anode type X-ray tube, a rotary anode and a rotary structure supporting the anode are arranged within the vacuum envelope. A stationary shaft has a middle section which is fitted into a cylindrical portion of the rotary structure, and a dynamic pressure type radial bearing is arranged between the cylindrical portion and the middle section. The stationary shaft also has a first section between one end of the middle section and one end of the stationary shaft, and a second section between the other end of the middle section and the other end of the stationary shaft, which are fixed to the vacuum envelope. A transverse stiffness of the second section is set to be larger than a transverse stiffness of the first section, and a center of gravity is positioned in the middle section.
