Abstract: An x-ray target assembly is formed by passing a rotary shaft through the center hole of a graphite disk such that the back surface of the disk rests on a flange part of the rotary shaft and the front surface is contacted by a nut which engages with the tip of the rotary shaft. Annular brazing materials are placed adjacent contact areas where the disk contacts the rotary shaft and the nut such that braze joints are made to secure the disk with the nut and the rotary shaft. Grooves may be formed on the surfaces of the nut and the flange part of the rotary shaft which contact the disk such that the brazing material can more efficiently fill the gaps between contacting surfaces.

Abstract: A rotating anode structure for an X-ray tube is provided, having a lightweight target anode. A carbon-carbon composite target substrate has constituents and weave geometries. A refractory metal focal track layer is deposited on the substrate to produce X-rays. An interlayer is disposed between the focal track layer and the substrate to relieve thermal expansion mismatch stresses between the carbon-carbon composite anode target substrate and the refractory metal focal track layer. The interlayer is a rhenium interlayer and the focal track layer is typically a tungsten-rhenium focal track layer.

Abstract: A rotatable x-ray target assembly and process for manufacturing the same is provided for an x-ray tube. The x-ray target assembly comprises an x-ray target member having an opening disposed therethrough and a support member having: a mounting surface disposed transversely to the axis of rotation, a lower surface of the target member being disposed on the mounting surface; and, a threaded stem extending from said mounting surface through the opening of the target member. The support member also comprises a nut adapted to receive the threaded stem, the nut engaging an upper surface of the target member. The target member is secured to the support member by brazing material disposed between the lower surface of the target member and the mounting surface, a first portion of the brazing material being diffused into the target member and a second portion of the brazing material being diffused into the mounting surface of the support member. With such arrangement, the target member is structurally bonded to the support member. Thus, the target member is substantially prevented from slipping on the support member during the rotation of the x-ray target member during operation of the x-ray tube, thereby preventing the target member from becoming imbalanced on the support member and substantially eliminating vibration of the target member during rotation.

Abstract: A bearing structure for an X-ray tube is provided that includes a journal bearing shaft with a radially protruding thrust bearing flange encased within a bearing housing or sleeve. The sleeve includes a thrust seal that is engaged with the sleeve in a manner to maintain coaxiality for the rotating liquid metal seal formed in the sleeve about the shaft. The shaft includes a central bore containing a cooling tube that directs coolant within the bore to maximize the heat transfer from the shaft to the coolant, allowing materials with lower thermal conductivities, such as steel, to be used to form the bearing shaft. The thrust flange on the shaft is formed with channel(s) therein that enable the coolant and/or the liquid metal to effect greater heat transfer on the components of the sleeve through the thrust flange, thereby reducing thermal deformation of the bearing components.

Abstract: The present invention relates to mounting of an anode disk. In order to provide a mount of an anode disk to a rotating shaft that is suitable for increased thermal loads on the anode disk, a rotating anode assembly (10) is provided that comprises an anode disk (12), a rotating shaft (14), and an anode disk support (16). The anode disk is concentrically mounted to a rotating axis (18) of the rotating shaft via the anode disk support, and the anode disk support comprises a first support (20) with a first circular axial support surface (22) that is provided at the rotating shaft in a concentric manner with the rotating axis. Further, the anode disk support comprises a second support (24) with a second axial support surface (26) that is at least temporarily attached to the rotating shaft for urging the anode disk against the first support surface in an axial clamping direction. Still further, the first support is provided as a radially flexible support (28). Upon heating up of the anode disk during X-ray generation, and a thermal expansion of the anode disk, the radially flexible support bends (32) radially such that the first axial support surface at least partly follows the thermal expansion in a radial direction.
