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.
Claims10
A torsional vibration damper having a longitudinal axis of rotation comprising:
- (a) a central hub having means for connection to a part to be damped;
- (b) an inertial damping mass spaced from the central hub to form a longitudinally extending gap surrounding the central hub;
- (c) an elastic ring disposed in said gap in adherent contact between the central hub and the inertial damping mass for connecting the central hub to the inertial damping mass, said elastic ring having
- (i) successive subsections along the circumferential direction of the elastic ring, with at least one of said subsections uniformly and smoothly merging into adjacent subsections and being spaced at a different distance from the longitudinal axis of rotation than the distance of other subsections from the longitudinal axis, said subsections being of uniform thickness;
- and
- (ii) a longitudinal profile that smoothly varies along the circumferential direction of the ring.
