Abstract
The invention relates to a rotary-anode X-ray tube which includes a sleeve bearing which is composed of an inner and an outer bearing segment, the outer bearing segment including intermediate pieces and a holder on which the intermediate pieces bear so as to transfer the bearing forces. Suitable shaping of the external surfaces of the intermediate pieces and the inner surfaces of the holder which contact these outer surfaces ensures that the intermediate pieces become aligned with the bearing surfaces on the inner bearing segment. This strongly reduces the complexity of manufacture.

A rotary-anode X-ray tube including a holder, the X-ray tube further including a sleeve bearing including equivalent first and second bearing surfaces at first and second ends of the sleeve bearing, which sleeve bearing serves to journal a rotary-anode comprising an anode disc, said X-ray tube further including a shaft associated with an inner bearing segment and an outer bearing segment, wherein first and second intermediate pieces are provided between the holder and the inner bearing segment and said bearing surfaces are correspondingly formed on the inner bearing segment, the intermediate pieces being arranged to take up radial and axial bearing forces,
- and wherein facing surfaces of the first and second intermediate pieces and the holder are formed in such a manner that the first and second intermediate pieces in the holder are respectively aligned with the first and second bearing surfaces.
A sleeve bearing which includes a holder the sleeve bearing including an inner bearing segment and an outer bearing segment wherein intermediate pieces are provided between the holder and the inner bearing segment and correspondingly formed bearing surfaces on the inner bearing segment, the intermediate pieces being arranged to take up radial and axial bearing forces, and wherein facing surfaces of the intermediate pieces and the holder are formed in such a manner that the intermediate pieces in the holder are aligned with the bearing surfaces.
