20090078079 | DECOUPLED VIBRATION DAMPER - A torsional vibration damper includes a one-piece integral hub and annular inertia mass assembly. Between the hub and the inertia mass are intermediate rings connected integrally with the mass and the hub connected integral spokes. Elastomeric members are compression fitted within spaces formed between the hub and the mass. With this design, the damper can be formed from a polymeric material with an embedded annular weight. | 03-26-2009 |
20090000422 | RECESSED BELT DAMPER - A torsional vibration damper includes an inertia mass and a rotating shaft or hub with an elastomeric ring between the inertia mass and the rotating shaft or hub. A large portion of said elastomeric member is located in a channel located either in the inertia mass or in the hub. This allows one to achieve high contact pressure without creating a significant fatigue on the elastomeric member. This can be used with either a crankshaft damper or an internal or external drive shaft damper. | 01-01-2009 |
20090000421 | COMPRESSED HUB DAMPER - A torsional vibration damper includes front and rear hub members with an inertia mass between the two hub members. Annular elastomeric rings are positioned between the front and rear hub members and the inertia mass holding the inertia mass. Fasteners extend through the front hub member, the inertia mass, and fixed to the rear hub member. A clearance between the fastener and the inertia mass allows relative motion to absorb torsional vibration. | 01-01-2009 |
