Title:
MANUFACTURE OF ROTATING ANODE X-RAY TUBE
Document Type and Number:
Japanese Patent JP3159663
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method of manufacturing a rotating anode X-ray tube in which the assembling of the X-ray tube can be simplified, the inclusion of a gas to a bearing constituting member or metal lubricating material can be suppressed to provide a high performance bearing operation.
SOLUTION: In this method of manufacturing a rotating anode X-ray tube, a lubricating material 20 to be supplied to dynamic pressure type slide bearing parts 12, 13, 14 is formed by preliminarily solidifying a metal material constituting the lubricating material 20 into plural kinds in the form of an alloy consisting of a single element or a plurality of elements, filling these solid matters 21, 22 into the area of the dynamic slid bearings 12, 13, 14, 28 of an anode assembly in the separate state, installing the anode assembly in the state filled with the solid matters in the vacuum chamber of an X-ray tube, separating it in the step of exhausting the internal space of the vacuum vessel to bring the filled lubricating material solid matters into contact with each other, and alloying them to an alloy having a melting point lower than the respective melting points.
