Sliding bearing i.e. liquid metal-sliding bearing, for axial bearing of rotary anode of X-ray tube, has bearing surfaces exhibiting grooves that are distanced by bar whose breadth is large in uneven manner

摘要

The bearing has a rotatable bearing part i.e. bearing frame, arranged outside or within a fixed bearing part (8) i.e. bearing axle, in a concentric manner, where the bearing is designed as an axial bearing. The bearing parts comprise bearing surfaces, and a bearing gap is provided between the bearing surfaces and filled with fluid agent. The bearing surface of the fixed bearing part and/or the bearing surface of the rotatable bearing part exhibit grooves (11a) that are distanced by a bar (11b) whose breadth (16) is large in an uneven manner.
