Seal for a torsional vibration damper

A torsional vibration damper, comprising two modules (1, 2) that rotate in relation to each other, and a spring chamber (7), said first module (1) having a first guide surface (30) and sealing the spring chamber (7) radially outward, said first guide surface being a baffle soldered to the first module (1).

A torsional vibration damper, comprising two modules (1, 2) that rotate in relation to each other, and a spring chamber (7), said first module (1) having a first guide surface (30) and sealing the spring chamber (7) radially outward, whereby the first guide surface is at a distance from the second module (2) across a gap (31) and is essentially radial, wherein between the first and second guide surfaces (30, 50) there is provided a sealing ring (4) that covers the gap between the first guide surface (30) and the second module (2) at least when the torsional vibration damper is at rest, and further comprising an essentially radial second guide surface (50) which covers the gap (31) on the spring chamber side, and a guide disk for holding the sealing ring (4) under radial, inward pretension, said guide disk forming one of the two guide surfaces and so designed that the pretension is reduced when the torsional vibration damper rotates.
