Abstract
A rotary anode x-ray tube includes a vacuum vessel in which a cathode, an anode target, a connecting rod, a rotor, bearings, and a heat conducting plate are arranged. The cathode electrode emits electrons. The anode target generates x-rays when electrons emitted from the cathode electrode collide with the target. The connecting rod supports the anode target. The connecting rod is constituted by a rod member consisting of a pulverized sintered material. The rotor is mounted on the connecting rod. The anode target is rotatably supported by the bearings. The heat conducting plate is arranged between the anode target and the rotor. A heat conducting plate made of a material having excellent heat conduction characteristics can be arranged between the anode target and the rotor. The connecting rod is manufactured by processes such as plasticization including tube spinning.
