Slide bearing for rotating anode of X-ray tube, has bearing surface comprising grooves, which are arranged at distance from each other by rod, where depth of grooves is not transversely constant to grooves

摘要

The bearing has a fixed bearing part (8), and a rotatable bearing part (9) that is concentrically arranged outside or within the fixed bearing part. The bearing parts comprise a bearing surface (14a) and another bearing surface, and a bearing gap (15) is provided between the bearing surfaces and is filled with a liquid unit i.e. liquid metal. One of the bearing surfaces comprises grooves (11a), which are arranged at a distance from each other by a rod (11b). Depth of the grooves is not transversely constant to the grooves. The grooves are parallel together. An independent claim is also included for a method for manufacturing a ramp-shaped groove of a slide bearing.
