ABSTRACT:
A tuned torsional viscous damper has mounted on a flat supporting disk a ring-shaped inertia mass comprising a pair of complementary stamped heavy gauge annular sheet metal inertia plates each of which has a radially outer axially facing annular portion in parallel shear film spaced relation to the disk body having regard to viscous damping medium in the damper, radially outer extremities of said radially outer annular portions being secured together, radially inner annular axially facing portions of substantial width of the stamped inertia plates being substantially offset axially away from the disk body by means of annular transversely angular integral offsetting bends connecting the radially inner portions to the radially outer portions, elastic tuning spring, spacing and sealing rings bonded in the recesses defined by the radially inner plate portion and extending into bonded engagement with the disk body.
