Impact mechanism for a rotary impact tool

Abstract

An impact mechanism for a rotary impact tool including a centering component, a gear carrier adapted to receive rotational force from the motor and including a gear carrier aperture adapted to receive the centering component, an anvil rotatable about the central axis and including an impact section and an anvil aperture adapted to receive the centering component, and a hammer slidably coupled to the gear carrier, rotatable about a central axis, and defining a planar surface, the hammer including a lug extending from the planar surface. The centering component functions as a pilot between the gear carrier and anvil. The centering component can include an axial bore. Axial clearance and a slip-fit can be provided between the gear carrier and the centering component and between the anvil and the dowel to allow the hollow dowel to move axially.
