Abstract
The present invention relates to an X-ray tube with a rotary anode and to a process for fixing a rotary anode to a support shaft contained in such a tube. The rotary anode is fixed to the support shaft with the aid of a deformed element, positioned between the rotary anode and the support shaft, concentrically to the latter, and acting in the manner of a stuffing box.
Claims13
An X-ray tube comprising:
- a rotary anode having first and second opposite faces;
- an axial bore passing through a central portion of the rotary anode, the bore extending into at least one enlarged coaxial recess which is formed inwardly of a first corresponding anode face;
- a rotating shaft coaxially received in the bore and recess;
- and
- at least one permanently deformed ductile ring located within the recess and press fitted between a wall of the recess and an adjacent section of the shaft so as to secure the anode to the shaft and preventing relative motion therebetween.

A method for securing an X-ray anode to a rotatable shaft comprising the steps:
- forming an axial bore through a central portion of the anode which extends into at least one enlarged coaxial recess which is formed inwardly of a first anode face;
- positioning a rotatable shaft through the bore and recess;
- placing a ductile ring within the recess;
- and
- subjecting the ring to forces causing permanent deformation of the ring until it becomes press fitted between a wall of the recess and an adjacent section of the shaft so as to secure the anode to the shaft and preventing relative motion therebetween.
