  • Patent number: 11280383
    Abstract: A crankshaft damper for attachment to one end of a crankshaft of an engine. The crankshaft damper includes an elastomeric member attached to a hub, and an inertia ring connected to the hub through the elastomeric member. Several different structures for cooling the elastomeric member are disclosed that dissipate heat away from the elastomeric member. Air flow is induced near the elastomeric member by providing air flow openings in the inertia ring or the elastomeric member.
