Abstract

SE PRESENTA UNA ESTRUCTURA DE CIERRE HERMETICO PARA UN PRECALENTADOR DE AIRE PARA MANTENER UNA SEPARACION CONSTANTE ENTRE EL TAMBOR (48) Y LAS PLACAS DE SECTOR DEFORMABLES (176). HAY UNOS PUNTALES O HACES QUE REGULAN LA DESVIACION (120) QUE SE EXTIENDEN A TRAVES DE LAS PLACAS DE SECTOR (176) Y QUE SE DOBLAN DE UNA MANERA QUE CORRESPONDE AL CAMBIO DE FORMA QUE SUFRE EL TAMBOR (48) CUANDO CAMBIA SU TEMPERATURA. LOS EXTREMOS EXTERIORES DE LOS PUNTALES ESTAN CONECTADOS A UN ANILLO EXTERIOR (110) QUE QUEDA ENGANCHADO AL TAMBOR MEDIANTE UNAS GUIAS (100). A MEDIDA QUE EL TAMBOR (48) SE DEFORMA DE TAL MODO QUE SUS EXTREMOS ASUMEN UNAS CURVATURAS ESFERICAS PARCIALES APROXIMADAMENTE EN RESPUESTA A TEMPERATURAS MAYORES, LOS PUNTALES (120) SE DEFORMAN DE LA MISMA MANERA. LA DEFORMACION DE LAS PLACAS DE SECTOR (176) ES CONTROLADA POR LOS PUNTALES MAS RIGIDOS (120).
