Abstract
Official abstract text for this publication.
The invention relates to a rotary-anode X-ray tube which includes a sleeve bearing having an axial bearing section and a radial bearing section. Furthermore, radial sealing sections ( 601, 602 ) are provided in an outer bearing member ( 605, 607, 608 ) which have no functional relation to the axial bearing surfaces ( 2012 ) of the axial bearing section. Thus, additional sealing principles like gaskets or sealing edges can be used although this may result in degradation of surface parallelism.
First claim
Opening claim text (preview).
The invention claimed is: 1. A rotary-anode X-ray tube, comprising: a sleeve bearing with an inner bearing member and an outer bearing member having axial bearing surfaces adapted for taking up axial bearing forces and radial bearing surfaces adapted for taking up radial bearing forces; wherein the outer bearing member encloses the inner bearing member and comprises at least one radial sealing section; wherein none of the radial sealing sections has a functional relation to the axi…
