Abstract: A torsionally elastic coupling for a machine part rotating about an axis, comprising an inner ring open axially in one direction, which axial opening is defined by two flank surfaces and one bottom surface, and an outer ring, having an annular axial leg extending parallel to the axis, which is received in the axial opening of the inner ring, and which is supported with respect to one flank surface of the axial opening by a guide ring, and which is connected to the other flank surface of the axial opening by means of a damping ring made of elastomeric material, the guide ring and damping ring being configured integrally and continuously with one another, and made of elastomeric material.

Abstract: A vibration absorber includes an absorber mass and at least one spring element formed of an elastomer material. The absorber mass is arranged for movement on the spring element and is movable with a phase displacement relative to vibrations introduced due to operating conditions. The spring element is fixed on a vibration generator. A supplementary spring is assigned to the spring element and acts in parallel therewith to compensate for temperature effects. The supplementary spring has a spring stiffness. An aid is provided for changing the spring stiffness of the supplementary spring.
