Abstract
Viene descritta aria macchina per la pressatura meccanica che utilizza un albero a gomiti , in cui una forza inerziale squilibrata generata durante il movimento alternativo di un cursore viene annullata senza generare una sollecitazione di flessione nell'intera macchina per la pressatura, migliorando perciò la precisione dinamica. Un peso equilibratore, di peso equivalente a quello del cursore, che viene sostenuto scorrevolmente verticalmente su un telaio, viene montato scorrevolmente su una porzione superiore del cursore per un movimento di scorrimento verticale. Il cursore viene azionato tramite un primo albero a gomiti ed una barra di collegamento, e contemporaneamente il peso equilibratore viene spostato in una direzione opposta alla direzione di movimento del cursore tramite un primo ingranaggio fissamente montato sul primo albero a gomiti, un secondo ingranaggio, un albero intermedio, giunti elastici, un secondo albero a gomiti ed una barra di collegamento. Come risultato, la forza inerziale generata nel cursore viene annullata dalla forza inerziale diretta in direzione opposta del peso equilibratore.
