Title: X-ray tube liquid metal bearing structure for reducing trapped gases
Inventor: HUNT IAN STRIDER
IPC: F16C33/10
Filed: 2022-02-07
Abstract: To provide a bearing structure for an X-ray tube.SOLUTION: The bearing structure includes a journal bearing shaft with a radially protruding thrust bearing encased in a bearing sleeve, where one of the sleeve and the shaft rotates relative to the other. A stationary component, e.g., a journal bearing and/or the thrust bearing includes at least one vent groove formed therein that improves the ability of a journal bearing structure to enable gases trapped by a liquid metal within a bearing assembly to escape through the vent groove to the exterior of an X-ray tube. By adding a strategically located channel or vent groove of sufficient size in at least one of the journal bearing or the thrust bearing, the pressure resisted by a seal created between the liquid metal and the vent groove in the bearing components is significantly reduced, allowing escape of the gases to avoid detrimental effects on the operation of the X-ray tube, while maintaining the load carrying capacity of the bearing assembly.SELECTED DRAWING: Figure 1
