Abstract

SISTEMA DE TRANSMISION CONTINUAMENTE VARIABLE, QUE TIENE UNA POLEA FIJA DE DIAMETRO VARIABLE CONECTADA, POR UNA BANDA MOTORA, A CUANDO MENOS OTRA POLEA. UNA POLEA MANTIENE LA TENSION DE LA BANDA MOTORA DENTRO DE LIMITES PREDETERMINADOS, A MEDIDA QUE VA CAMBIANDO EL DIAMETRO EFECTIVO DE LA POLEA DE DIAMETRO VARIABLE. EL DIAMETRO EFECTIVO DE LA POLEA DE DIAMETRO VARIABLE ESTA DETERMINADO POR UN BALANCE ENTRE UNA FUERZA ELASTICA, QUE INFLUYE EN UNA PLURALIDAD DE MIEMBROS QUE ENGRANAN LA BANDA EN SENTIDO PREDETERMINADO, Y UNA FUERZA RADIAL QUE ACTUA EN SENTIDO CONTRARIO EN LA PLURALIDAD DE MIEMBROS QUE ENGRANAN LA BANDA. EN UNA PRIMERA FORMA DE REALIZACION, LA FUERZA ELASTICA DERIVA HACIA AFUERA LA PLURALIDAD DE MIEMBROS QUE ENGRANAN LA BANDA, Y LAS FUERZAS RADIALES ESTAN GENERADAS POR EL DESPLAZAMIENTO DE LA POLEA TENSORA, PARA AUMENTAR LA TENSION DE LA BANDA MOTORA.
