Abstract
A hydrostatic bearing assembly or structure for an x-ray tube and associated process for manufacturing and operating the bearing assembly is provided to reduce and potentially eliminate wear from landing or takeoff of the rotating component of the bearing assembly on the non-rotating component. The shaft and sleeve are separated by a gap in which an amount of a liquid metal is placed in order to provide the sleeve with the ability to rotate about the shaft, or vice versa. The non-rotating component of the hydrostatic bearing assembly is formed with a number of fluid channels extending through the component and in communication with the gap. The liquid metal is pumped into and out of the gap via the channels under pressure supplied by a magnetohydrodynamic pump to maintain the separation of the rotating and non-rotating components of the bearing assembly.
