Abstract

A torsional vibration damper has a first flywheel mass on the drive side and a second flywheel mass which is rotatable relative to the first flywheel mass and is connected therewith via a torsional damping device. At least one of the flywheel masses is provided with a grease chamber containing a viscous medium for at least partial accommodation of the torsional damping device. There is at least one opening which is provided with a closure and axially penetrates at least one wall of the flywheel mass for filling the grease chamber with the viscous medium. The closure is formed by a cover which is accommodated at the respective flywheel mass and movable in the axial direction relative to the opening. In a sealing position the cover covers the opening, and a filling position is removable from the opening by a connection piece which can be guided through the opening for filling the grease chamber.
