Abstract

A rotating anode is mounted on a shaft of an X-ray tube by means of a ring. The ring allows expansion and reduces the hyperstatic state of the assembly. The ring has the shape of a diabolo, preferably that of a hyperboloid structure generated by revolution. The ring dampens vibration phenomena in a shaft bearing the rotating anode and reduces noise-creating phenomena.

Claims

exact text as granted — not AI-modified
1 . A method for the manufacture of a diabolo comprising: 
 forming slots in a plate, the slots being interposed with non-inclined parallel beams, the parallel beams being held together at their ends by lintels;    shaping the plate around a circular chuck with an axis perpendicular to the lintels; and    twisting the circularly shaped lintels, with respect to each other, about an axis collinear with the axis of the chuck to incline the beams.    
   
   
       2 . A method for the manufacture of a diabolo comprising: 
 forming slots in a plate, the slots being interposed with parallel beams, the parallel beams being held together at their ends by lintels, the beams being inclined in relation to a direction perpendicular to the lintels;    deforming the formed plate by being forced into a mold with a shape generated by revolution, with an axis of revolution orthogonal to the directions of the lintels; and    the mold having an embossment in a central part between the ends that receive the lintels.    
   
   
       3 . The method according to  claim 1  wherein the plate is a parallelogram.  
   
   
       4 . The method according to  claim 2  wherein the plate is a parallelogram.  
   
   
       5 . The method according to  claim 1  wherein the plate is rectangular.  
   
   
       6 . The method according to  claim 1  wherein the formed slots are straight between the lintels.  
   
   
       7 . The method according to  claim 2  wherein the formed slots are straight between the lintels.  
   
   
       8 . The method according to  claim 1  wherein the formed slots are rectilinear between the lintels.  
   
   
       9 . The method according to  claim 2  wherein the formed slots are rectilinear between the lintels.  
   
   
       10 . The method according to  claim 1  wherein the formed slots are oriented at a right angle to the direction of the lintels.  
   
   
       11 . The method according to  claim 2  wherein the formed slots are oriented at a right angle to the direction of the lintels.  
   
   
       12 . The method according to  claim 1  wherein an aperture is formed in at least one diametrically opposite parts of the lintels.  
   
   
       13 . The method according to  claim 2  wherein an aperture is formed in at least one diametrically opposite parts of the lintels.  
   
   
       14 . The method according to  claim 1  wherein an aperture is formed in two diametrically opposed parts of the lintels.  
   
   
       15 . The method according to  claim 2  wherein an aperture is formed in two diametrically opposed parts of the lintels.  
   
   
       16 . A method for the manufacture of a diabolo comprising: 
 forming a diabolo from a cylinder by removing portions of the cylinder; and    forming beams in a wall of the diabolo, the beams being inclined.    
   
   
       17 . The method according to  claim 1  wherein the inclination of the beams is about 50° relative to an axis of the diabolo.  
   
   
       18 . The method according to  claim 2  wherein the inclination of the beams is about 50° relative to an axis of the diabolo.  
   
   
       19 . The method according to  claim 3  wherein the inclination of the beams is about 50° relative to an axis of the diabolo.  
   
   
       20 . The method according to  claim 5  wherein the inclination of the beams is about 50° relative to an axis of the diabolo.  
   
   
       21 . The method according to  claim 6  wherein the inclination of the beams is about 50° relative to an axis of the diabolo.  
   
   
       22 . The method according to  claim 8  wherein the inclination of the beams is about 50° relative to an axis of the diabolo.  
   
   
       23 . The method according to  claim 10  wherein the inclination of the beams is about 50° relative to an axis of the diabolo.  
   
   
       24 . The method according to  claim 12  wherein the inclination of the beams is about 50° relative to an axis of the diabolo.  
   
   
       25 . The method according to  claim 14  wherein the inclination of the beams is about 50° relative to an axis of the diabolo.  
   
   
       26 . The method according to  claim 16  wherein the inclination of the beams is about 50° relative to an axis of the diabolo.  
   
   
       27 . The method according to  claim 17  wherein the inclination of the beams is 50°±10°.  
   
   
       28 . The method according to  claim 17  wherein the inclination of the beams is 50°±5°.  
   
   
       29 . The method according to  claim 1  wherein the diabolo shape has twist angle greater than or less than 50°.  
   
   
       30 . The method according to  claim 2  wherein the diabolo shape has twist angle greater than or less than 50°.  
   
   
       31 . The method according to  claim 16  wherein the diabolo shape has twist angle greater than or less than 50°.  
   
   
       32 . method according to  claim 1  wherein the diabolo has a hyperboloid shape.  
   
   
       33 . method according to  claim 2  wherein the diabolo has a hyperboloid shape.  
   
   
       34 . method according to  claim 16  wherein the diabolo has a hyperboloid shape.  
   
   
       35 . The method according to  claim 32  wherein the hyperboloid shape has an inner curvature diameter that is less than the initial diameter.
