Title: Rotating anode x-ray tube unit
Inventor: HARADA TOSHIO
IPC: H05G1/04
Filed: 1989-02-27
Abstract: PURPOSE:To prevent any damage to bearings with restraining them from any temperature rise so as to secure the long-livedness of an X-ray tube by installing a cooling device around the internal circumference of a cylindrical supporting body for a rotating anode in non-contact with the circumference. CONSTITUTION:When electron beams are applied to a rotating anode 3 from a cathode 2, X-rays are generated for storing heat into the anode 3 to cause a rise in its temperature. Although most of the heat is carried away from the surface of the anode 3 to the outside, part of the heat flows through a cylindrical supporting body 4 to a motor rotor 5 and on to a rotating shaft 6. At this time, heat 23 radiated from within the internal circumference of the supporting body 4 is caught to permit the upward escape thereof by means of a cooling device 21 inserted around the internal circumference of the supporting body 4. Thus, the amount of heat flowing in the direction of each of bearings 7, 8 is reduced for reducing a rise in the temperature of a bearing stage to prevent any damage to the bearings while securing the long-livedness of an X-ray tube.
