Abstract

The application discloses a liquid metal sliding bearing, an X-ray tube and a CT scanning device. The liquid metal sliding bearing comprises a rotating core (100), a rotating member (200) capable of rotating relative to the rotating core (100), and liquid metal arranged between the rotating core (100) and the rotating member (200), wherein the rotating member (200) comprises a rotating housing (210) and a rotating flange (220) connected with the rotating housing (210), the rotating housing (210) and the rotating flange (220) are arranged along the axis of the liquid metal sliding bearing, a first sealing structure is formed between the rotating housing (210) and the rotating flange (220), and the first sealing structure comprises a first annular boss (241) formed around the axis of the liquid metal sliding bearing.

Description

technical field [0001] The present application relates to the technical field of X-ray tubes, in particular to a liquid metal sliding bearing, an X-ray tube and a CT scanning device. Background technique [0002] At present, liquid metal sliding bearings are widely used in X-ray tubes. The rotating assembly of the liquid metal sliding bearing is generally composed of multiple parts, and the parts are fixed by screws. Due to machining accuracy, there must be a small gap between the contact surfaces of the two parts of the rotating assembly. Therefore, when the rotating assembly rotates at high speed, under the action of centrifugal force, the liquid metal will overflow from the gap in the radial direction. Aiming at the problem of radial leakage of liquid metal sliding bearings, the existing anti-leakage method is to plate a flexible coating on the gap on the surface of the part or install a flexible gasket to avoid the centrifugal force of the liquid metal from the two sid...
