Abstract

EL CAMBIO DE VELOCIDADES VARIABLE COMPRENDE UN EJE DE DIRECCION (3) Y UN EJE MOTRIZ (9) ACOPLADOS POR UNA UNION DE DISCO DE FRICCION (10), Y ESTA ACOMODADO EN UNA CAJA FIJA (8) DANDO PASO Y SOPORTE AL EJE MOTRIZ, Y UNA CUBIERTA (2), AJUSTABLE POR POSICION EN RELACION A LA CAJA FIJA Y PRODUCIENDO PASO Y SOPORTE AL EJE DE DIRECCION; EL ESPACIO ENTRE LA CUBIERTA AJUSTABLE (2) Y LA CAJA (8) SE PUENTEA MEDIANTE UN SELLO, TIPO JUNTA IMPERMEABLE (13), SUJETO EN SUS CANTOS INTERIOR Y EXTERIOR (13I,13E) EN AJUSTE IMPERMEABLE AL FLUIDO ENTRE LA CUBIERTA (2) Y LA CAJA (8), RESPECTIVAMENTE, Y CAPAZ DE FLEXIONAR AL MENOS RADIALMENTE EN RELACION A LOS DOS EJES (3,9). LA CUBIERTA (2) INCORPORA UNA PROTUBERANCIA (12) EXTENDIENDOSE A TRAVES DEL CENTRO DE LA ABERTURA DE LA JUNTA DE SELLADO (13) DENTRO DE LA CAJA (8) Y UNIENDOSE CON VASTAGOS (11) MEDIANTE EL MOVIMIENTO DE LOS CUALES SE COLOCA LA CUBIERTA, Y SE OPTIMIZA, PLEGANDO EL SELLO CON ONDULACIONES (14) EXTENDIENDOSE HACIA AFUERA ALREDEDOR DE LA PROTUBERANCIA.FIG 1.
