Title (EN) A RECIPROCATING WORKPIECE DEVICE WITH A DRIVE SYSTEM SEEKING THE RESONANCE OF THE DRIVEN SYSTEM PORTION THEREOF
(FR) DISPOSITIF DE PIECE A MAIN A VA-ET-VIENT DOTE D'UN SYSTEME D'ENTRAINEMENT QUI CHERCHE LA RESONANCE DE LA PARTIE DU SYSTEME ENTRAINEE
Abstract:
(EN) A workpiece system with a reciprocating motion which includes a motor assembly for producing an output drive signal with a periodic force pulse. The drive signal is coupled to a driven member assembly through a magnetic arrangement, wherein the driven member assembly has a workpiece mounted thereon with a return spring assembly. The driven member assembly has a resonant mechanical frequency. As the RPM of the motor increases from zero following startup, the drive signal frequency increases to the point very near resonance, where the energy from the drive signal is transferred into the reciprocating motion of the driven assembly, producing an effective amplitude of workpiece motion.
(FR) L'invention concerne un système de pièce à main à mouvement de va-et-vient, qui comprend un ensemble moteur conçu pour produire un signal d'entraînement de sortie comportant une impulsion de force périodique. Le signal d'entraînement est injecté par l'intermédiaire d'un montage magnétique, dans un ensemble à élément mené, sur lequel une pièce à main est montée avec un ensemble ressort de rappel. L'ensemble à élément mené possède une fréquence mécanique résonante. Etant donné que le nombre de tours/minute augmente depuis zéro après le démarrage, la fréquence du signal d'entraînement augmente jusqu'au point très proche de la résonance, l'énergie provenant du signal d'entraînement étant transférée en mouvement de va-et-vient de l'ensemble entraîné, ce qui permet d'obtenir une amplitude efficace du mouvement de la pièce à main.
