Abstract
The present invention relates to mounting of an anode disk. In order to provide a mount of an anode disk to a rotating shaft that is suitable for increased thermal loads on the anode disk, a rotating anode assembly (10) is provided that comprises an anode disk (12), a rotating shaft (14), and an anode disk support (16). The anode disk is concentrically mounted to a rotating axis (18) of the rotating shaft via the anode disk support, and the anode disk support comprises a first support (20) with a first circular axial support surface (22) that is provided at the rotating shaft in a concentric manner with the rotating axis. Further, the anode disk support comprises a second support (24) with a second axial support surface (26) that is at least temporarily attached to the rotating shaft for urging the anode disk against the first support surface in an axial clamping direction. Still further, the first support is provided as a radially flexible support (28). Upon heating up of the anode disk during X-ray generation, and a thermal expansion of the anode disk, the radially flexible support bends (32) radially such that the first axial support surface at least partly follows the thermal e…
