Abstract
A rotary anode X-ray tube has an anode connected at one end of a shaft which is magnetically mounted within the X-ray tube at its opposite end, the shaft simultaneously forming a rotor connected to a drive system for rotating the anode. The X-ray tube housing is formed by a number of connected components, two such components being spaced at opposite ends of the rotor, with the rotor extending therethrough, and each having stop bearings which are normally not in contact with the rotor, but which serve to limit movement of the rotor and the anode connected thereto, in the event of a malfunction in the magnetic mounting. Integration of the anode shaft and the drive rotor enable placement of the stop bearings at locations which minimize the lever action of the rotor-shaft-anode combination thereby significantly improving stability of the total assembly.
