Abstract
In the case of tubes with magnetically mounted anodes, it is difficult to obtain an adequately stable mounting of the anode shaft for all stresses to be expected, in particular, in the case of tilting and pivoting. To this end, the disclosure provides that magnetically conductive pole pieces are inserted in the wall of the tube envelope at the locations at which magnets are exteriorly disposed which pole pieces are in magnetic coupling relation with the anode arrangement. The distances between the parts to be magnetically coupled can thereby be substantially reduced, so that there results--in relation to known magnetic bearings--a substantially more stable support-mounting of the rotary anode in the high vacuum envelope. The disclosure is, in particular, applicable in the case of X-ray tubes for utilization in medical X-ray technology.
