Abstract:
1. A drive shaft torsional vibration damper comprising; a tubular inertia mass having an annular channel that includes opposing first and second side walls, a preformed elastomeric member, wherein at least 20% of said elastomeric member is located in said annular channel with a portion of said elastomeric member extended beyond said channel, said elastomeric member in continuous contact and compressed against a surface of a drive shaft less than 10% such that said elastomeric member exerts a compressive force against said surface of said drive shaft to maintain said drive shaft torsional vibration damper in position and provide a requisite slip torque, said elastomeric member having an interior surface and an exterior surface, which are generally concentrically oriented with respect to one another, and having opposing side surfaces; wherein said elastomeric member has a portion of each of said opposing side surfaces bounded by said first and second side walls of said annular channel.
