<p>A torsional vibration damper (10, 68, 78, 88) mountable to a rotatable shaft (11). The torsional vibration damper (10, 68, 78, 88) is a composite structure including a body (18) formed of a polymer, such as a glass-reinforced polyamide, that surrounds an insert (16) formed of a Structurally-rigid material, such as a metal. The insert (16) includes one or more support flanges (50) that extend radially outward into the polymer body (18). When the torsional vibration damper (10, 68, 78, 88) is removed from the rotatable shaft (11), axial forces applied to the damper (10, 68, 78, 88) are transferred by the support flanges (50) to the insert (16) such that the polymer body (18) remains substantially stress-free. In addition to, or instead of, the support flanges (50), the insert (16) may include torque-locking structure (70, 80, 90) that locks the polymer body (18) with the insert (16) to prevent relative rotation therebetween.</p> |
