Abstract
A damper for a crankshaft of a reciprocating engine includes an inner shell and an inertia ring, the inner shell and the inertia ring having a plurality of teeth and grooves that are intermeshed with one another. The damper further includes a plurality of damping pads positioned between the teeth of the inner shell and the grooves of the inertia ring. The inertia ring is constrained from translating in the axial direction and the radial direction with respect to the inner shell and is rotatable with respect to the inner shell in the circumferential direction through a constrained range by compressing the damping pads.
