ROTATING ANODE X-RAY TUBE

摘要

A rotating anode X-ray tube according to the present embodiment is provided with: a rotating cylinder (5) to which an anode target is fixed; a rotating shaft (7) coaxially fixed to an inner side of the rotating cylinder; an anode stator (18) that is disposed between the rotating cylinder and the rotating shaft and that is formed of one of a magnetic material member formed of a magnetic material and extending in an axial direction and a heat-transfer enhancement member having a heat conductivity higher than that of the surroundings thereof; ball bearings (11, 12) that are provided between the anode stator and the rotating shaft; and an inner member (19) that is disposed between the anode stator (18) and the rotating shaft (7), that is connected to the anode stator (18) via a connection member, and that is formed of one of the magnetic material member and the heat-transfer enhancement member, the one being different from the member forming the anode stator.
