METHOD FOR RESISTANTLY AND TIGHTLY FIXING A HOLLOW CYLINDRICAL ELEMENT AT THE INSIDE OF A TUBE, AND CYLINDRICAL ELEMENT FOR CARRYING OUT THIS METHOD

摘要

At least one ring (2) of material having a hardness greater than that of the tube (3) and that of the hollow cylindrical component (1) is arranged around the latter in contact with its outer surface. The cylindrical component is introduced inside the tube (3) and then expanded and crimped at least in its part containing the ring of hard material (2), thereby embedding the ring in the cylindrical component (1) and in the tube (3) at the same time.
