Cylinders or tubes assembled by means of a new method for eliminating interference

Method for joining two or more concentric cylinders (101, 102) by isostatic-pressure interference, being one or two of said cylinders already interference-joined;

• auxiliary cylindrical tubes (201, 202), caps (211, 212, 213, 214) and assembly chamber (301) of high pressure to be used as tools of the process for joining by isostatic-pressure interference;
• elastic and structural guides to push one cylinder into another, being inside the assembly chamber (301);
• wherein each pair or set of concentric cylinders (101, 201) and (102, 202) is prepared with the respective caps (211, 212), (213, 214) welded or glued forming auxiliary or tubular chambers such that they are subjected to pressure within the assembly chamber (301) with liquid or gas, taking into consideration that no pressure enters the interior of the tubular chambers through the caps, where both consecutive tubular chambers must be so assembled with a gadget and small guides, such that when the pressure rises and the interference disappears—as the pressure increases the diameter of the cylinder (101) of the larger tubular chamber and decreases the diameter of the cylinder (102) of the smaller tubular chamber, it is in conditions then to fit, slide and put the smaller tubular chamber into the larger tubular chamber through the guide that was made for such effect, thus fitting as the mechanism for such effect is activated, where said mechanism can go on the interior of the tubes of smaller radius or on the outside;
• after the sliding or adjustment is produced, the pressure of the assembly chamber (301) is released from the already fitted cylinders, variation in the diameters is produced and the tubes that are joined by interference (101 and 102) tend to return to the initial diameter;
• the auxiliary cylinders are removed and only both cylinders are left joined by interference.
