Abstract

A torsional vibration damper for a shaft rotating about an axis. The damper comprises a hub element joined to the shaft, such that at least two inertial masses, pivotable in the peripheral direction about pivot axes, are retained on the hub element. At least one spring for each inertial mass is provided to determine the static position of the inertial masses. The pivot axes lie between the inertial masses and the axis of the shaft.
