<p>1. A damper for reducing the torsional vibration of a shaft and/or for preventing transmission thereof, of the type comprising a boss which is fixed with respect to the shaft and a peripheral inertia ring mounted concentrically around the boss, the boss and the ring being rotationally associated by a resilient damping element inserted in a housing formed between a radially outward surface of the boss and a radially inward surface of the ring, said surfaces of the boss (3, 23) and the ring (4, 22) extending parallel to the axis (XY) of the boss, characterized in that said faces (3, 23) and (4, 22) form, perpendicularly to the axis (XY), two parallel contours defining between them, for the annular resilient element (6, 24), a housing of substantially constant thickness in the form of a regular polygon having rounded corners (6A, 6B, 6C and 6D).</p> |
