Abstract: A method for assembling a rotating X-ray tube, the X-ray tube having a cathode for emitting electrons, and a rotor and a bearing assembly for facilitating rotation of an anode. The method includes using an interference fit assembly between the bearing assembly and the rotor to provide a joint having balance retention. The using interference fit assembly further includes selecting a rotor hub of the rotor having a coefficient of thermal expansion which results in a composite coefficient of thermal expansion for the rotor assembly which closely matches that of a shaft of the bearing assembly. The shaft and aperture in said rotor hub are configured to interference fit tolerances and then joined providing a joint having balance retention. An interference fit joint between a shaft extending from a bearing assembly and a rotor hub is also disclosed, wherein the joint is completed without using any mechanical fasteners or metallurgical bonding, yet can carry all of the operational loads placed on the joint.

Abstract: An x-ray tube 10 is provided including an anode mounted to a rotatable shaft positioned within a center bore of a stem element, a bearing assembly positioned between the rotatable shaft and the stem element, and at least one liquid metal shunt in thermal communication with both the rotatable shaft and the stem element, located adjacent to the anode between the anode and the bearing assembly, and directing heat generated at the anode away from the bearing assembly by allowing heat to flow from the rotatable shaft into the stem element prior to heat reaching the bearing assembly.

Abstract: A rotary-anode-type X-ray tube comprising an anode target, a rotary cylinder supporting the target, and a stationary shaft having radial dynamic-pressure slide bearings to which a liquid-metal lubricant is supplied between the rotary cylinder and the stationary shaft and formed partially having a small-diameter portion with an outside diameter smaller than those of the slide bearings. The X-ray tube is provided with a plurality of reservoirs from which ducts extend. All the ducts open in the small-diameter portion.
