Abstract

LA INVENCION SE REFIERE EN PARTICULAR A UN MONTAJE DE EJE DE SUJECCION PERFECCIONADO (10) QUE COMPRENDE UN EJE DE SUJECCION (16) QUE TIENE UNA PRIMERA PORCION DE EJE (18) ADAPTADA PARA SER INTRODUCIDA A TRAVES DE UN PASO (26) EN EL EXTREMO DEL REBORDE (14) DE UN CONTROL BARRA GUIA-TUBO PARA SER FIJADA ALLI POR MEDIO DE UNA TUERCA (40) Y UNA SEGUNDA PORCION DE EJE (20) QUE COMPRENDE UNA SECCION DE ARMAZON DE HENDIDURA-HOJAL (24) Y ESTA ADPATADO PARA SER ALBERGADO EN UN HUECO (22) DE LA PLACA SUPERIOR DEL NUCLEO-REACTOR (12). ADYACENTE AL TERMINO CONTIGUO DE LA PRIMERA PORCION DE EJE, LA SEGUNDA PORCION DE EJE (20) ESTA PROVISTA CON UNA SECCION DE ARMAZON SOLIDO (50) QUE ESTA PREPARADO PARA FORMAR UNA HOLGURA PROXIMA AJUSTADA A LA PARED DEL HUECO DE LA PLACA NUCLEO (22) PARA ACTIVAR COMO CIZALLA PASA SOBRE ALGUN PESO LATERAL APLICADO AL EJE DE SUJECCION (16), LA SECCION DE ARMAZON DE HENDIDURA-HOJA (24) INCLUYE UN VASTAGO DE HENDIDURA (54) QUE TIENEN UNA DIMENSION DIAMETRAL MAS PEQUEÑA QUELA SECCION DE ARMAZON SOLIDO Y SE EXTIENDE AXIALMENTE DESDE ALLI TERMINANDO EN UNA SECCION TERMINAL DE HENDIDURA (56) PREDISPUESTA CONTRA LA PARED DEL HUECO DE LA PLACA NUCLEO (22). LA TUERCA (40) FORMA ALLI INTEGRALMENTE UNA EXTENSION TUBULAR (60) ENGARZADA A LA SECCION TERMINAL (28) DE LA PRIMERA PORCION DE EJE PARA PREVENIR UNA SEPARACION AUTOMATICA DE LA TUERCA, Y UNA HENDIDURA LONGITUDINAL DE UN FORRO UNIFORME DE UN SUJETADOR DE TUERCA (70) QUE ESTA PROVISTO PARA BLOQUEAR LA TUERCA (40) CONTRA EL REBORDE DEL TUBO GUIA (14).
