Rotary anode type X-ray tube |
摘要 |
In a rotary anode type X-ray tube, a rotary anode and a rotary structure supporting the anode are arranged within the vacuum envelope. A stationary shaft has a middle section which is fitted into a cylindrical portion of the rotary structure, and a dynamic pressure type radial bearing is arranged between the cylindrical portion and the middle section. The stationary shaft also has a first section between one end of the middle section and one end of the stationary shaft, and a second section between the other end of the middle section and the other end of the stationary shaft, which are fixed to the vacuum envelope. A transverse stiffness of the second section is set to be larger than a transverse stiffness of the first section, and a center of gravity is positioned in the middle section.
