摘要： The present invention provides, in one embodiment, a bearing assembly consisting of a rotatable shaft and a stator coaxially aligned. The stator has at least one circumferential protrusion that contains respective segments that extend radially from the stator. Each of the respective segments contains at least one capture cavity and has a main cavity disposed between each of the respective segments so as to house a thermal shunt. A plurality of roller bearings are also disposed radially between the rotatable shaft and the stator. In addition, at least one viscoseal is disposed on the rotatable shaft.

摘要： X-ray source bearing assemblies are described herein. In an exemplary embodiment, an x-ray source includes a target anode, a rotor shaft coupled to the target anode, and a motor coupled to the rotor shaft at an end of the shaft opposite the target anode. The bearing housing, in the exemplary embodiment, includes a rotor bore, the rotor shaft extending through said rotor bore and supported therein by a plurality bearings. The housing and the shaft form a cooling medium pool so that as the shaft rotates, a cooling medium in the pool is radially displaced.
