Abstract

TUERCA AUTOBLOQUEANTE PARA BARRAS DE ACOPLAMIENTO DE CONJUNTOS DE COMBUSTIBLE. PROCEDIMIENTO Y APARATO PARA BLOQUEAR BARRAS DE ACOPLAMIENTO IMPIDIENDO QUE GIREN RESPECTO A LA PLACA SUPERIOR O INFERIOR. SE USA UNA TUERCA CONVENCIONAL, PARA ENROSCARLA EN LA EXTREMIDAD ROSCADA SUPERIOR DE LAS BARRAS, LLEVANDO SUJETAS UNAS ALETAS EXTENDIDAS AL EXTERIOR, INTERFIRIENDO, CUANDO GIRAN, CON UN CANAL DE HAZ DE COMBUSTIBLE INSTALADO, DONDE LA TUERCA CON ALETAS SE HACE GIRAR ENCIMA DE LA PLACA CON LAS BARRAS. PARA ELLO, LAS TUERCAS CON ALETAS SE GIRAN EN UN ANGULO QUE NO CREA INTERFERENCIA CON EL CANAL. SEGUIDAMENTE, EL CANAL INTERFIERE CON EL TRAYECTO DE ROTACION DE LAS ALETAS DE LA TUERCA IMPIDIENDO LA ROTACION RELATIVA ENTRE BARRA DE ACOPLAMIENTO Y TUERCA CON ALETAS. ASI, AL DESMONTAR EL HAZ, SOLO DEBE RETIRARSE EL HAZ Y SE HACE GIRAR DE FORMA CONVENCIONAL LA TUERCA CON ALETAS CON FUERZA SUFICIENTE PARA SUPERAR EL BLOQUEO DE LA TUERCA, FACILITANDOSE EL DESMONTAJE DE UN CONJUNTO DE HAZ DE COMBUSTIBLEPARA INSPECCION.
