Abstract: The invention teaches a method of manufacturing a torsional vibration damper in which a metal hub ring and a metal inertia ring surrounding the hub ring are radially spaced apart by a gap. A spring body of rubber-elastic material is fired into the gap with the aid of a lubricant, the spring body and/or the surfaces of hub and/or inertia ring facing the gap being wetted with a lubricant composed of a water-salt solution prior to insertion of the spring body.

Abstract: A rotary vibration damper for a shaft where the flywheel ring 1 and the hub 2 are connected by first resilient elements 3 uniformly distributed in the circumferential direction, and where second resilient elements 4 of an essentially column-like shape are provided between the first resilient elements 3. The second resilient elements are affixed at one end to the hub 2 and at the other end to the flywheel ring 1. When the rotary vibration damper does not rotate, these elements have a bend 7 in the intermediate zone which protrudes radially inward. This bend 7 can be reduced and eventually eliminated at higher speeds by centrifugal forces, thus causing the spring rigidity to increase.
