Abstract
A device for dampening torsional vibrations, comprising a centering sleeve (1) for the reception of a rotatable element and a flywheel mass (2) is characterized in that, with regard to the objective to be solved, namely the realization of an arrangement having a constructively simple design and a highly dynamic stability, the centering sleeve (1) and the flywheel mass (2) are connected to each other. Furthermore, an arrangement comprising the mentioned device and a flexible coupling (5) is claimed.
Claims7
Device for dampening torsional vibrations comprising a centering sleeve with a center and two ends and tapered towards one end, for the reception of a first shaft end, the centering sleeve having an outer circumference, wherein the centering sleeve is at least partially arranged within a flywheel mass and said flywheel mass is adjacent said center, and wherein the centering sleeve and the flywheel mass are connected to each other by an elastomer arranged at said outer circumference, and an elastic layer is arranged within the centering sleeve, wherein the centering sleeve further includes an inner sleeve for centering of a second shaft end and wherein said inner sleeve has an outer surface and the elastic layer surrounds the outer surface of said inner sleeve.
