摘要： An integrated component mounting system that includes a component mounted to a shaft and secured in place by a nut. The component and the nut each define respective annular shaped surfaces. The shaped surfaces are each inclined at a similar angle and are arranged for sliding contact with respect to each other. As the nut is tightened on the shaft, the shaped surface of the nut exerts both radial and axial forces on the shaped surface of the component, thereby automatically centering the component radially on the shaft as well as securing the component at a desired location along the shaft.

摘要： The present invention is directed to a radiographic apparatus that utilizes a single integral housing for providing an evacuated envelope for an anode and cathode assembly. The integral housing provides sufficient radiation blocking and heat transfer characteristics such that an additional external housing is not required. The integral housing is air cooled, and thus does not utilize any coolant. In addition, the integral housing is insulated with a potting material, which electrically insulates the integral housing and its components, and also limits the amount of noise emitted from the housing during operation. In an alternative embodiment, enhanced thermal and electrically insulating properties are achieved through the use of a potting material disposed in selected areas of the tube interior. The potting material cooperates with optimized airflow through the tube assembly to effectively and continuously remove heat therefrom.

摘要： A high energy x-ray tube includes an evacuated chamber (12) containing a rotor (34) which rotates an anode (10) in the path of a stream of electrons (A) to generate an x-rays (B) and heat. The rotor includes a bearing shaft (54, 80, 122) connected to the anode by a thermally conductive structure (40). The bearing shaft carries soft metal-lubricated bearing balls (44F, 44R) in forward and rear bearing races (64, 66, 106, 108, 128, 130). An annular groove (70, 94, 132) is defined longitudinally in the shaft which, particularly when evacuated, provides a thermal barrier between the forward race and the portion of the shaft that is thermally connected with the anode. The groove lengthens the path heat entering the bearing shaft travels in order to reach the forward bearing race. As a result, the temperature of the forward race, and hence the evaporation of lubricant during operation of the x-ray tube, is reduced. The groove may be formed by electrical discharge machining the bearing shaft or by forming the shaft from inner and peripheral components (124, 126) which are connected together adjacent the rear bearing race (130).
