Title:
DUAL RING DAMPER
Document Type and Number:
WIPO Patent Application WO2002008633
Kind Code:
A3
Abstract:
The invention comprises a dual ring damper. The damper comprises an inner ring (20) for connecting the damper to a crankshaft. It also comprises an outer inertial ring (30) for contacting a belt or the like. A flexible elastomeric material (7) is mechanically contained in an annular space between the inner ring and the outer ring. The inner surface of the outer ring and the outer surface of the inner ring each describe a complex, non-arcuate cooperating profile of cross-section that mechanically fixes the elastomeric between them. The elastomeric does not use chemical adhesives to bond with either the inner or the outer ring, instead relying on mechanical containment between the rings. The elastomeric in the preferred embodiment comprises EPDM.
