  • Patent number: 7184520
    Abstract: A component mounting system that includes a rotor stem, nut, and mechanical interface. The mechanical interface defines a shaped surface and is integral with the component. An axial opening in the component permits the component to be mounted on the rotor stem. The nut defines a second shaped surface and one or more annular slots. As the nut is advanced along a threaded portion of the rotor stem, the shaped surfaces contact each other and serve to automatically center the component on the rotor stem. The annular slot defined by the nut permits the nut to elastically deform under the influence of various operating conditions, and thereby alleviate forces that are exerted on the elements of the component mounting system.

  • Patent number: 6749101
    Abstract: A method for manufacturing x-ray tube parts wherein metallic pieces are explosively bonded together to establish a high strength, stable union between them. The x-ray tube parts may then be milled from the bonded metallic pieces. The explosion bonding process creates only discrete intermetallic components in the joint region instead of a continuous, weakening intermetallic layer common in brazed joints. An explosion bond joint is characterized by a wavelike interface, thereby increasing surface area over which the components are bonded and further increasing bond integrity. Rotor sleeves and other tube components may be manufactured using this method.

  • Patent number: 5425067
    Abstract: An X-ray tube construction of the rotating anode type for reducing acoustic noise and vibration by using granules which are placed loosely within an anode cavity formed between the outer surface of an anode shank and a wall of an anode sleeve in proximity to a bearing journaled to a rotor shaft for rotation of an anode structure.
