Abstract
A torsional vibration damper has a longitudinal axis of rotation about which an inertial damping mass is disposed. The inertial damping mass, which may be in the form of a ring, surrounds the periphery of a central hub connected to a shaft to be damped. The hub is connected to the damping mass by an elastic ring disposed in the space between the damping mass and hub to connect the damping mass and hub. The elastic ring may be formed of rubber or other suitable elastomeric material, and has a longitudinal profile that varies along the circumferential direction of the elastic ring.
