<p>Torsional vibration damper comprising an essentially cup-shaped hub ring (1) made of deep-drawn sheet metal, the bottom (2) of which has at least one opening (3) to allow it to be fastened to a machine part (4) that can be subjected to torsional vibrations, the hub ring (1) being connected, with the ability for relative rotation, to at least one inertia ring (6) by means of at least one spring element (5) made from elastomeric material. The bottom (2) is provided with an annular centring collar (7) which extends in the axial direction and which surrounds the outer circumference (8) of the machine part (4), making partial contact with the latter, the centring collar (7) and the bottom (2) being designed in such a way as to merge integrally into one another. <IMAGE></p> |
