Abstract

Abstract A rotary anode arrangement for X-ray tubes wherein the anode plate and the driving rotor are connected with each other and are also connected with the connection of both outer rings of two bearings spaced from each other. Their inner rings lie upon a shaft constituting the rotary axis and located in a tubular piston. The invention is particularly characterized in that the driving rotor as well as the connection to the anode plate extend along the spacing between the two bearings and are fixed to the connection of the two bearings close to the edge of the bearing distant from the plate. At least a part of the connection between the plate and the attachment to the bearings consists of a tube with thin walls which constitutes a resilient element for selected sizes.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 112 words
An X-ray tube with a rotary anode, comprising an anode plate, a driving rotor and two spaced bearings, each of said bearings having an inner ring and an outer ring one of said bearings being located closer to said anode plate than the other bearing, a thin-walled resilient tube having one end connected with said anode plate and connected at least adjacent to its other end with the driving rotor and the outer ring of said other bearing, which ring is connected with the outer ring of said closer bearing, and a shaft fastened to the bulb of the X-ray tube, the inner rings of the bearings being connected to said shaft.
Claim 2
Dependent Claim 112 words
An X-ray tube with a rotary anode, comprising an anode plate, a driving rotor and two spaced bearings, each of said bearings having an inner ring and an outer ring one of said bearings being located closer to said anode plate than the other bearing, a thin-walled resilient tube having one end connected with said anode plate and connected at least adjacent to its other end with the driving rotor and the outer ring of said other bearing, which ring is connected with the outer ring of said closer bearing, and a shaft fastened to the bulb of the X-ray tube, the inner rings of the bearings being connected to said shaft.
Claim 3
Dependent Claim 21 words
