Abstract
A method for assembling a rotating X-ray tube structure ensures balance retention during the life of the tube. The X-ray tube structure has a cathode for emitting electrons, and a rotor and a bearing assembly for facilitating rotation of an anode. At least one joint is identified in the X-ray tube structure and interference fit assembly is used to eliminate shifts at the joint. The interference fit assembly is particularly advantageous for eliminating even the minutest shifts in the main joints of the anode assembly. Interference fit assembly can be applied between the rotor and the anode target to provide a first joint having balance retention; and interference fit assembly can be applied between the bearing assembly and the rotor to provide a second joint having balance retention.
