  • Method and device for mounting a rotating member
    Publication number: 20070101794
    Abstract: A rotating anode is mounted on a shaft of an X-ray tube by means of a ring. The ring allows expansion and reduces the hyperstatic state of the assembly. The ring has the shape of a diabolo, preferably that of a hyperboloid structure generated by revolution. The ring dampens vibration phenomena in a shaft bearing the rotating anode and reduces noise-creating phenomena.

  • Assembly for mounting a radiation emitting device, radiation emitting device having such an assembly, and a radiological apparatus having such an assembly and emitting device
    Patent number: 6888923
    Abstract: A bearing assembly for the rotational mounting of a rotary anode of an X-ray emitting device on a support having at least one rolling bearing provided in order to be placed between the rotary anode and the support, the rolling bearing having a rotating ring, a non-rotating ring, and rolling elements placed between raceways of the first ring and of the second ring. At least one sleeve is intended to be mounted between an axially stressed ring of the rolling bearing and a cylindrical bearing surface of the anode or of the support, the sleeve being radially elastic in order to compensate for variations in radial dimensions between the ring and the cylindrical bearing surface, and in order to dampen the vibration, while at the same time being suitable for allowing the ring to slide axially with respect to the cylindrical bearing surface.
