Abstract
A low frequency torsional vibration damper has an annular inertia member defining an annular recess for receiving an elastomeric O-ring in a radial outer surface or a radial inner surface thereof and defining opposing annular recesses for receiving elastomeric O-rings, one each, in the top and bottom surfaces thereof, an elastomeric O-ring seated in each annular recess, and a hub defining an annular receptacle with opposing sidewalls that each comprise a plurality of spaced apart tabs permanently deformed against the plurality of elastomeric O-rings, thereby operatively coupling the hub to the inertia member for rotation together. When the inertia member defines the outer diameter of the torsional vibration damper, the hub is mountable on a shaft, and when the inertia member defines the inner diameter of the torsional vibration damper, the hub is mountable inside a shaft.
