Sealing for torsional vibration damper

摘要

A torsion oscillation dampener has two facing and rotating aggregate groups of components in a spring chamber (7). The first aggregate group (1) of components has a guide face (30) which seals the spring chamber (7) radially outwards. The guide surface is separated from the second aggregate group (2) by a gap (31) and has an axial surface area component directed towards the spring chamber. A second guide surface (50) has an axial surface area component directed towards the spring chamber, covering the gap (31) on the spring chamber side.
