Patent ID: 8689956

Claim:
A torsional vibration damper, comprising: a receptacle disposed around an axis of rotation, having an outer circumference; and, several absorber masses guided radially on raceways in the receptacle and limitedly pivotally held in circumferential direction with a radially outside contour and a radially inside contour, which extends over a circumferential segment of the receptacle, wherein: the outside contour is restricted to the outer circumference of the receptacle during displacement of the absorber mass along the raceways; the outside contour or inside contour comprise different radii based on a rotation angle around the axis of rotation; the inside contour of the absorber masses is formed respectively by a circular segment extending in both circumferential directions from a zero line of the absorber mass; and, an inside contour between the circular segments is formed straight over a given length in the form of a line section.
