Crankshaft damper and method of assembly

Abstract

A crankshaft damper and a method of crankshaft damper assembly using interlocking beads. A crankshaft damper having a hub portion and pulley ring and an elastomeric member disposed in an annular space between them is clamped in a tool after initial assembly. A tool having jaw teeth on oppositely disposed, cooperating jaws engages the crankshaft damper hub portion and pulley ring on either side of the elastomeric member. The tool jaws press on the hub portion and pulley ring to create beads or crimps on the hub portion and the pulley ring. The beads or crimps are formed in cooperating groups or sets. They press the elastomeric member into the form of a curve or wave. The curve or wave mechanically locks the hub portion and pulley ring together, thereby locking the elastomeric member in place between them.
