    Abstract: A bearing assembly suitable for use in conjunction with x-ray device having a rotating target anode and electron source disposed in an evacuated enclosure. The bearing assembly includes a shaft having a rotor hub to which the anode is mounted. The shaft cooperates with front and rear bearing rings to define front and rear races, and a spacer facilitates positioning of the bearing rings. Front and rear ball sets are confined in the front and rear races, respectively. A bearing housing receives the bearing rings, spacer, front and rear ball sets, and part of the shaft. Finally, a magnet is disposed near the front bearing ring to prevent escape of foreign matter from the bearings and to prevent ingress of foreign matter to the bearings. Consequently, the magnet serves to extend the life of the bearings and to prevent foreign matter related arcing of the target anode and electron source.

    Abstract translation: 一种适合与x射线装置一起使用的轴承组件，其具有设置在抽真空的外壳中的旋转目标阳极和电子源。 轴承组件包括具有转子毂的轴，阳极被安装到该转子毂上。 轴与前后轴承圈配合以限定前后座圈，并且间隔件有利于轴承环的定位。 前球和后球分别限制在前后比赛中。 轴承座接收轴承环，间隔件，前后球套和轴的一部分。 最后，磁铁设置在前轴承环附近，以防止异物从轴承中逸出，并防止异物进入轴承。 因此，磁体用于延长轴承的寿命并防止目标阳极和电子源的异物相关电弧。

    Abstract: Various methods and systems are provided for providing coatings and textures to surfaces of a bearing assembly in an x-ray system to control the wettability of the surfaces when components of the bearing assembly rotate during operation of the x-ray system. A lubricant is disposed in a gap formed between a shaft and a sleeve of the bearing assembly such that textured and coated surfaces of the shaft and sleeve alter wetting properties between the lubricant and surfaces. The coatings and textures can be wetting or anti-wetting to further enhance control over the behavior of the lubricant.

    Abstract: There is provided an X-ray tube device having a configuration for preventing peeled-off solid lubrication films from scattering in an X-ray tube even when the solid lubrication film peels off a rotary bearing. The X-ray tube device includes: an anode (212) that is irradiated with an electron beam, thereby emitting X-rays; a rotary bearing (304) that rotatably supports the anode (212); a solid lubrication film which is formed on a front surface of the rotary bearing (304) and into which a ferromagnet is mixed from the rotary bearing (304); and an attractor (303) which attracts, with a magnetic force, the solid lubrication film that peels off the rotary bearing (304).
