Abstract

MECANISMO DE TORNILLO Y TUERCA PARA EL MANDO DE UN REACTOR NUCLEAR. CARACTERIZADO PORQUE EL ORGANO DE ARRASTRE UNIDO AL EJE DEL MOTOR (4), LLEVA UNA PARTE PERFILADA, DESTINADA A ENGRANAR CON UNA PARTE CORRESPONDIENTE DEL ELEMENTO MOVIL EN ROTACION DEL CONJUNTO TORNILLO-TUERCA, AL OBJETO DE SOLIDARIZAR DICHAS PIEZAS EN ROTACION, DEJANDOLAS SIMULTANEAMENTE LIBRES DE DESPLAZARSE UNA RESPECTO DE LA OTRA EN TRASLACION VERTICAL; PORQUE LLEVA UN TORNILLO (12), MOVIL EN TRASLACION, CUYA PARTE INFERIOR PUEDE ESTAR UNIDA AL CONJUNTO ABSORBENTE, POR MEDIACION DE UN VASTAGO DE UNION Y UNA TUERCA (15), FIJA EN TRASLACION Y MOVIL EN ROTACION; Y PORQUE EL ORGANO DE ARRASTRE DE LA TUERCA (15) ESTA CONSTITUIDO POR UNA CAMISA (20) Y UN TUBO QUE SE INTRODUCE EN EL TUBO PORTA-TUERCA (16).
