Apparatus for the radial shaping of tubular articles

Apparatus for the radial shaping of rotors, spindles, shafts and the like comprising a frame having at least two guiding segments situated between a left side wall and a right side wall, said guiding segments being provided with an outer rolling surface, a freely rotatable supporting ring encompassing said guiding segments, at least two rollers rotatably supported on eccentric pins fixed on the supporting ring to engage respective ones of said segments, rods interposed between said rollers, sliding shoes, bearing forming jaws, connected to the inner end of said rods, the outer end of said rods being pivotally connected on supporting pins fixed to the supporting ring so that the sliding shoes with the associated forming jaws are adapted to perform a radial movement between said guiding segments on movement of said supporting ring, the supporting ring being provided on its external circumference with at least one eyelet for a connection with a connecting rod, the other end of which is supported by an eccentric sleeve, which in turn is supported by an eccentric pin connected to a driving shaft;

• said driving shaft having an eccentric pin and an eccentric sleeve and including a dish-shaped carrier keyed on said eccentric pin of the driving shaft, said carrier provided on its internal face with an indentment, the eccentric sleeve on the eccentric pin of the driving shaft provided on its side adjacent to the dish-shaped carrier with a corresponding indentment.
