Vibration damper and heat sink for reciprocating saw - has axially and radially movable carrier guide controlled by eccentric

摘要

The vibration damping and heat sink mechanism for a reciprocating hand-held saw has a carrier guide with limited axial and radial movement positively controlled by an eccentric. The carrier guide serves both as a counterweight and a heat sink. A drive shaft for the eccentric also drives a wobble mechanism for reciprocating a saw blade carrier slidably mounted in the carrier guide. The relative movement of the carrier guide with respect to the saw blade carrier and their relative weights are such that a perfect balance may be obtained when aggressive orbital action of the saw blade and saw blade carrier is used as in the case of cutting wood.
