Abstract

UN TENSOR DE CORREAS QUE CONSTA DE UNA ESTRUCTURA FIJA (3), UN BRAZO (4) QUE SE PUEDE MOVER RESPECTO A UN EJE (7) DE LA ESTRUCTURA FIJA, UN RESORTE DE TORSION (6), UN PAR DE CONOS DE AMORTIGUACION (8), (9) ASOCIADOS A LA ESTRUCTURA FIJA Y AL BRAZO, UN RESORTE DE COMPRESION (10) QUE ACTUA SOBRE LOS CONOS AMORTIGUADORES. EL RADIO MEDIO DE LOS CONOS ES MENOR QUE LA DIMENSION RADIAL MAXIMA DEL RESORTE DE TORSION. EL VALOR "I" DEL BRAZO SE CORRELACIONA CON EL RADIO MEDIO DE LOS CONOS DETERMINANDO UNA AMORTIGUACION DE FRICCION ENTRE LOS CONOS MENOR QUE LA EXISTENTE ENTRE EL EJE Y EL BRAZO ROTATIVO.
