Abstract:
An X-ray tube is disclosed having a cathode and rotating anode located within a glass envelope. The rotating anode comprises an annular disc forming the target area. The disc is integrally connected to a stem which in turn is connected to a hollow cylindrical rotor. The interior of the cylindrical rotor extends over the anode support shaft and bearing structure. The anode shaft supports the rotor, stem and anode disc and is integrally connected thereto via a thin-walled, cup-shaped member made of a low heat conductive metal. The interfaced connections with the cup-shaped element are accomplished through minimal contact surfaces to provide a thermal barrier against the heat energy generated in the anode structure, thereby preventing the heat energy from passing through to the shaft and bearing structure.
