Abstract
A torsional vibration damper having a longitudinal axis of rotation includes a central hub and a rotatable inertial ring surrounding the central hub that are connected together by a damping element arranged in the clearance space between the hub and inertial ring. The damping element comprises an outer ring, an inner ring and a flange ring disposed therebetween. The outer ring is connected between substantially axially, opposed adhesive surfaces of the inertial ring and the flange ring, respectively. The inner ring is connected between substantially radially opposed, adhesive surfaces of the flange ring and the hub ring. The adhesive surfaces of the hub ring and the flange ring each surround the axis of rotation at a radial distance that continuously varies along the circumferential direction.
