Abstract
A bonding system for assembling internal combustion engine crankshaft vibration dampers having an annular inertia ring mounted upon a hub by an elastomeric ring interposed between the inertia ring and hub. After assembly of the components, a thermosetting adhesive located between the elastomeric ring and the inertia ring and hub is heated to a bonding temperature by low frequency electrical induction. The damper components are mechanically clamped during heating and the elastomer is permitted to thermally expand. Heat is concentrated adjacent the adhesive to minimize thermal aging and degrading of the elastomer.
