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

X-ray emitting device comprising:

• a cathode;
• a rotary anode;
• the rotary anode being mounted so that it can rotate on a support by means of a bearing assembly;
• the bearing assembly comprising:
• at least one rolling bearing provided to be placed between the rotary anode and the support, the rolling bearing comprising a rotating ring, a non-rotating ring, and rolling elements placed between raceways of the first ring and of the second ring;
• and
• at least one sleeve is 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, while at the same time being suitable for allowing the ring to slide axially with respect to the cylindrical bearing surface.

A radiological apparatus comprising:

• means for emitting radiation;
• means for receiving the emitted radiation;
• the means for emitting radiation comprising:
