Abstract

A rotating anode disk is balanced in a state where the rotating anode disk is mounted inside an X-ray tube. An adjustment device ( 54 ) balances the rotating anode disk in an operating state. The adjustment device includes at least a first plurality ( 72 ) of balancing elements ( 74 ) which are attached to at least one circular ring structure ( 76 ). The balancing elements each include a balancing portion ( 80 ) mounted to the circular ring structure via a bending portion ( 82 ). The bending portions are configured to be heated to a bending temperature to allow a radial pivoting movement ( 84 ) of the balancing portion from a first state ( 86 ) into a second state ( 88 ) caused by centrifugal forces upon rotation. A center of mass of the balancing portion is closer to a center ( 90 ) of the circular ring structure in a first state than the second state.

First claim

The invention claimed is:

1. An adjustment device for balancing a rotating anode disk in an operating state, the adjustment device comprising:
at least a first plurality of balancing elements;
wherein the balancing elements are attached to at least one circular ring structure;
wherein the balancing elements each comprise a balancing portion mounted to the circular ring structure via a bending portion;
wherein the bending portions are configured to be heated to a bending temp…
