ABSTRACT:
The rotary output of the power source of an impact device is converted to reciprocation of a body, preferably having a resilient coupler, which drives a ram into impacting in an improved rotary-to-reciprocative motion converter including a crankshaft operatively interconnected to reciprocate the body. The converter includes a crankpin bearing, a flat bearing surface secured normal to the reciprocation on a connecting rod or directly on the body, and a constraint spring to hold the flat bearing surface in contact with the bearing during operation. The improved converter provides reciprocation free of angular motion of connecting rods and irregular motion within clearances between moving elements to significantly reduce extraneous harmonic vibrations and energy losses therefrom.
