Abstract: A bearing assembly for a rotating anode x-ray device. The bearing assembly includes a shaft having a flange at one end for attachment of the anode thereto. The shaft defines front and rear inner races and includes a plurality of extended surfaces. Front and rear outer race elements define front and rear outer races, respectively, corresponding to the front and rear inner races, respectively, defined by the shaft. The front and rear outer race elements cooperate with the shaft to confine front and rear ball sets which facilitate rotary motion of the shaft. A spacer including extended surfaces assists in the positioning of the front and rear outer race elements in a bearing housing. The extended surfaces of the shaft and spacer, in conjunction with emissive coatings provided on various portions of selected components of the bearing assembly, facilitate a relative improvement in heat transfer out of the bearing assembly.

Abstract: A high energy x-ray tube includes an evacuated chamber (12) containing a rotor (34) which rotates an anode (10) in the path of a stream of electrons (A) to generate an x-ray beam (B) and heat. Heat is carried away from the anode to a bearing shaft (54) which rotates relative to a stationary rotor (42) on forward and rear lubricated bearings (44P, 44R). The heat is directed away from the forward bearings (44F), by a core (70) of a thermally conductive material, such as copper, disposed in a central cavity (60) within the shaft. Annular insulating regions (74,76) are optionally defined between the core and the bearing shaft adjacent the races to increase the thermal path between the anode and the races. The reduction in temperature of the forward bearings results in a decrease in the evaporation rate of the lubricant (46) and a corresponding increase in the lifetime of the x-ray tube.

Abstract: A structure and associated method for forming a liquid metal or spiral groove bearing assembly for an x-ray tube is illustrated that utilizes a unitary sleeve and a thrust ring or seal each formed of a weldable, non-refractory material. The sleeve and the thrust seal are welded to one another to provide an improved construction for minimizing leaks of the liquid metal bearing fluid. The structure of the sleeve and the thrust seal are formed with deformation restricting features that maintain the integrity of the bearing surfaces of the assembly when the thrust seal is secured within the sleeve and welded thereto to form the bearing assembly.
