Abstract

Perfeccionamientos en herramientas manuales accionadas con motor de combustión interna, especialmente martillo perforador cincelador que presenta una rueda volante unida con el cigüeñal del motor, caracterizados porque entre el cigüeñal y la rueda volante está dispuesto un engranaje multiplicador que eleva el número de revoluciones de la rueda volante respecto al cigüeñal.Improvements in internal combustion engine-powered hand tools, especially chipping hammer drills that have a flywheel connected to the engine crankshaft, characterized in that between the crankshaft and the flywheel there is a multiplier gear that increases the number of revolutions of the wheel flywheel relative to the crankshaft.
