Abstract

EN UN GRUPO DE COMBUSTIBLE QUE TIENE UNA MATRIZ DE VARILLAS DE COMBUSTIBLE ADYACENTES PARALELOS COLOCADOS ENTRE UN PLACA DE ANCLAJE INFERIOR Y UNA PLACA DE ANCLAJE SUPERIOR SE MUESTRA UNA CONSTRUCCION DE RESORTE Y VIROLA PARA LOS ESPACIADORES NECESARIOS PARA MANTENER LAS VARILLAS DE COMBUSTIBLE EN SU ALINEACION ADYACENTE PRECISA. LAS VIROLAS ACOPLADAS (205) TIENEN CADA UNA ABERTURAS PARA CAPTURAR UN SOLO RESORTE (200) ENTRE LAS VIROLAS (205). LOS RESORTES DISPONEN DE UN CUERPO PRINCIPAL CONSTANTEMENTE DECAPADO QUE TIENE OREJETAS SALIENTES (202) EN LADOS OPUESTOS DE LOS RESORTES. LA FORMA DE LAS ABERTURAS PERMITE LA INSERCION DEL RESORTE DESPUES DE QUE LAS VIROLAS HAN SIDO SOLDADAS JUNTAS. LOS RESORTES ESTAN COMPRIMIDOS MIENTRAS SE INSERTAN. TRAS LA INSERCION LOS RESORTES VUELVEN A SU FORMA ORIGINAL Y SE ENCIERRAN ENTRE LAS VIROLAS (205). TRAS LA INSERCION DE LAS VARILLAS DE COMBUSTIBLE, LOS RESORTES (200) SE COMPRIMEN HASTA UNA POSICION INTERMEDIA, PERO SIGUEN DENTRO DE LAS ABERTURAS DE VIROLA. LOS RESORTES (200) PUEDEN INSERTASE PARCIALMENTE EN LAS VIROLAS Y MANTENERSE EN ESTADO COMPRIMIDO MIENTRAS SE INTRODUCEN LAS VARILLAS DE COMBUSTIBLE. ESTO REDUCE LAS FUERZAS SOBRE LAS VARILLAS DE COMBUSTIBLE Y REDUCE EL RASPADO DE LOS MISMOS DURANTE EL MONTAJE DEL GRUPO DE COMBUSTIBLE. DESPUES DE QUE SE INSERTAN LAS VARILLAS DE COMBUSTIBLE LOS RESORTES (200) SE INSERTAN TOTALMENTE.
