    Abstract: A rotary-anode X-ray tube having a rotor, a stationary shaft, and a sliding bearing connecting the rotor and the stationary shaft, forming a gap filled with liquid metal lubricant. The rotor has a first rotary member supporting an anode target and a second rotary member at which a sliding bearing is installed and which is coaxial with the first rotary member. The first and the second rotary members are connected at that end of the heat conductive path which is remote from the anode target. A heat insulating gap is formed at all fitting portions, but the remote end. Therefore, the temperature rise of the sliding bearing is controlled without using refregerant, and stable rotation of the bearing is secured.

    Abstract: A rotary-anode type X-ray tube wherein bubbles produced in the gap of a sliding bearing are securely and easily replaced with liquid metal lubricant, and the metal lubricant is prevented from leaking. The rotary anode is secured to a cylindrical rotary structure. A columnar fixed structure is secured to the rotary structure forming a gap between the rotary structure and fixed structure. A liquid metal lubricant fills the gap. Spiral grooves are formed on a part of the outer surface of the fixed structure and the sliding bearing is installed between the fixed structure and the rotary structure. The rotary structure and fixed structure are housed in a vacuum envelope. The gap of the sliding bearing is connected to the space inside the vacuum envelope through an annular space. A gap is formed between a ring block for blocking the opening of the rotary structure and the fixed structure. A spiral groove to return the metal lubricant to the annular space is formed on the outer surface of the ring block facing the gap, and the annular space is coated with a film repelling the metal lubricant. The annular space and the gap between the ring block and the fixed structure serve to separate from the metal lubricant in the sliding bearing, the bubbles produced therein.

    Abstract: A supporting member supports an anode target at one end thereof and is provided with an attachment portion around the outer circumference of the other end. The attachment portion is attached to the inner circumferential surface of the cylindrical portion of the second vacuum envelope member so that the heat conductivity from the supporting member to the second vacuum envelope member can be improved by means of the attachment portion. A terminal is provided at the end surface portion on the side of the other end of the second vacuum envelope member for applying a voltage to the anode target. The terminal is positioned away from the attachment portion so that the temperature of the insulating material that insulates the terminal can be kept low and the insulating characteristics can be ensured over the long term.

    Abstract: An anode target is roratably supported by a rotating mechanism having a rotary body and a staionary body. A fitted portion between the rotary body and the stationary body is formed of bearing areas having dynamic pressure type sliding bearings and a non-bearing area having a clearance between the rotary body and the stationary body larger than that in the bearing areas. The rotary body facing the non-bearing area is positioned where a time for heat transfer from the anode target is shorter than the rotary body facing the bearing areas. Thus, the characteristics of heat radiation from the anode target can be improved, and a stable bearing operation can be maintained.
