Abstract
A torsional vibration damper includes an inertia mass and a rotating shaft or hub with an elastomeric ring between the inertia mass and the rotating shaft or hub. A large portion of said elastomeric member is located in a channel located either in the inertia mass or in the hub. This allows one to achieve high contact pressure without creating a significant fatigue on the elastomeric member. This can be used with either a crankshaft damper or an internal or external drive shaft damper.
