High Inertia Driver System

摘要

A high inertia driver system for a fastening tool having an electric motor that drives a flywheel to contact a driver blade to drive a fastener into a workpiece. The high inertia driver system also has a return system which prevents the unintentional driving of a second fastener. The return system uses a return spring that controls the recoil energy of the driver blade after driving a fastener into a workpiece. The system achieves a long operational life for the fastening tool by increasing the number of return cycles of the driver blade free of a return spring failure.

1. A power tool, comprising:
an electric motor having a rotor and a rotor shaft coupled to a flywheel; and a driver blade adapted to drive a fastener into a workpiece, wherein the flywheel is adapted to impart a force upon the driver blade when a portion of the flywheel contacts a portion of the driver blade, and wherein the flywheel has an inertia of 0.10 g*m̂2 or greater when the flywheel contacts the portion of the driver blade.
