Abstract
A crankshaft vibration damper which has an unique elastomer member positioned between a hub and outer annular inertia member. The hub is configured for connection to the accessory drive end of the crankshaft. The inertia member may or may not be grooved to accept an accessory drive belt. The resilient elastomer member is dimensionally and chemically developed to dampen torsional and bending vibrations when assembled between a corresponding curved hub and inertia member. The radially outward or inward curvature of the hub and inertia member is selected to be sufficient to effectively reduce crankshaft bending vibration.
