DAMPER WITH INDUCED IMBALANCE

摘要

A torsion damper including: a plurality of springs; a first plate with a central axis; and a second plate with a central axis. The plurality of springs displaces the first and second plates so that the central axis for the first plate is radially offset from the central axis for the second plate. In one embodiment, the radial offset between the central axis for the first plate and the central axis for the second plate is fixed. In another embodiment, the first plate comprises a central bore and the second plate comprises an extruded cylinder; and the fixed alignment is maintained by contact between the central bore and the extruded cylinder.
