Abstract
UNA BOMBA DE FLUIDO REFRIGERANTE DE REACTOR NUCLEAR UTILIZA UN CONJUNTO (48) DE COJINETES DE RIÑONES PIVOTADOS PARA GIRATORIAMENTE MONTAR SU ARBOL (22) A TRAVES DEL ALOJAMIENTO (32) DE LA BOMBA. EL CONJUNTO (48) DE COJINETES INCLUYE UNA PLURALIDAD DE SEGMENTOS ARQUEADOS (52) DE COJINETES, COLOCADOS CABEZA CON CABEZA EN RELACION CIRCUNFERENCIALMENTE ESPACIADA PARA CIRCUNDAR EL ARBOL (22) Y PROPORCIONAR CONTACTO DE COJINETES CON EL, Y UNA PLURALIDAD DE PASADORES-PIVOTE (54), EXTENDIENDOSE CADA UNO RADIALMENTE ENTRE UN ANILLO (50) PARTIDO ANULAR EXTERIOR, UNIDO AL ALOJAMIENDO (32) DE LA BOMBA, Y UNO DE LOS SEGMENTOS (52) DE COJINETE. LOS PASADORES-PIVOTE (54) ESTAN MONTADOS PARA QUE REALICEN UN MOVIMIENTO DE PIVOTAMIENTO UNIVERSAL EN SUS EXTREMOS INTERNOS (54A) CON LOS RESPECTIVOS SEGMENTOS (52) DE COJINETES. LOS PASADORESPIVOTE (54), EN SUS EXTREMOS (54B) EXTERNOS, ESTAN MONTADOS EN AL ANILLO (50) ANULAR PARA QUE REALICEN UN DESPLZAMIENTO RADIAL AJUSTABLE, CAMBIANDO LA POSICION RADIAL DE LOSPASADORES-PIVOTE (54) RESPECTO AL ANILLO (50) ANULAR Y CON ELLO LA DE LOS SEGMENTOS (52) DE COJINETES RESPECTO AL ARBOL (22). SE DISPONE DE UNA PLURALIDAD DE COPAS DE SUJECION (72) PARA EL ACOPLAMIENTO DE LOS PASADORES-PIVOTE (54) EN RELACION DE BLOQUEO CON EL ANILLO ANULAR (50) PARA FIJAR LOS PASADORES-PIVOTE (54) EN LAS POSICIONES AJUSTADAS QUE SE DESEA RESPECTO AL MISMO.
