Abstract

UN VARIADOR PARA UNA TRANSMISION DE RELACION CONTINUAMENTE VARIABLE (CVT) DEL TIPO RODILLO DE TRACCION SEMITOROIDAL EN QUE SE PRODUCE UN CAMBIO DE RELACION CUANDO UN RODILLO (6) REALIZA UNA PRIMERA LIBERTAD DE MOVIMIENTO AL ROTAR ALREDEDOR DE UN PRIMER EJE O EJE DE PRECESION (10). ADEMAS, EL MONTAJE DEL RODILLO TIENE UNA LIBERTAD DE MOVIMIENTO ADICIONAL ALREDEDOR DE UN SEGUNDO EJE O EJE DE INCLINACION (16). EL EJE DE PRECESION (10) ESTAN INCLINADO EN UN ANGULO ( EL ANGULO DE COMBA ) RESPECTO A UN PLANO PERPENDICULAR AL EJE DE AROS DE RODAMIENTO, Y CADA VALOR DE EQUILIBRIO DEL ANGULO DE RELACION SE CORRELACIONA CON UNA ORIENTACION ANGULAR UNICA DEL RODILLO (6) ALREDEDOR DEL EJE DE INCLINACION (16).
