Abstract

MEDIOS DE PIVOTAMIENTO PARA HACER PIVOTAR EN VAIVEN UNA CARGA MECANICA TAL COMO UN MARTILLO DE IMPRESION ALREDEDOR DE UN EJE GEOMETRICO DADO Y CON UN ANGULO DE PEQUEÑA AMPLITUD. DOS RESORTES DE LAMINAS (14, 16) ESTAN SITUADOS EN PLANOS QUE FORMAN ENTRE SI UN ANGULO DADO, PERO AMBOS SON PERPENDICULARES AL PLANO DE PIVOTAMIENTO DE LA CARGA MECANICA (24). UN BASTIDOR (22) FIJO A LA CARGA MECANICA PIOVOTABLE UNE LOS EXTREMOS (21A, 21B, 21C, 21D) DE AMBOS RESORTES DE LAMINA, ESTANDO UNIDA A ESTOS LA CARGA MECANICA EN UN PUNTO EQUIDISTANTE DE SUS EXTREMOS UNIDOS. UNA FUENTE DE ENERGIA (30) HACE PIVOTAR A LA CARGA MECANICA DESDE SU POSICION DE REPOSO A LA DE TRABAJO O IMPRESION HACIENDO QUE LOS DOS RESORTES SEAN FLEXIONADOS POR TORSION.
