Abstract: Se proporciona un sistema para mantenimiento de precarga de uniones de piezas de tipo embridado con un perno (P) y dos piezas (B1, B2), que consta de medios de tuerca (10) con roscado interior(100) según un eje de roscado (e) y medios de arandela (11) para insertar en el perno. Los medios de tuerca (10) tienen superficie inferior biselada (101) y una porción de guiado (102) que se extiende en una determinada longitud (L1) a partir del borde interior de la porción biselada; y los medios de arandela (11) están previstos con una embocadura abocardada (110) inclinada que se prolonga a través de un orificio de guía cilíndrico (111) que se extiende en una longitud (L2) menor o igual la longitud (L1) de la porción de cuello (102) de los medios de tuerca. La embocadura (110) de los medios de arandela está prevista en forma de plano inclinado mixto, es decir con al menos dos tramos/secciones con diferente inclinación, teniendo el primer tramo (1100) más alejado del eje de roscado (e) una primera una inclinación distinta a la del bisel (101) de los medios de tuerca, mientras que el, al menos un, segundo tramo (1101) más próximo al eje de roscado (e) determinante de la zona de apoyo de la superficie inferior (101) de los medios de tuerca presenta una inclinación mayor que la de dicho primer tramo. Al cerrarse dichos medios de tuerca para mantener el pretensado aplicado mediante elongación del perno, al menos una zona de la superficie inferior de los medios de tuerca yace apoyada en dicho al menos un, segundo tramo (101) de la embocadura de la arandela y estando la porción de cuello (102) introducida en el orificio cilíndrico de guía (111) para así distribuir el esfuerzo de la precarga en sus componentes normal y axial, reduciendo las pérdidas de precarga tanto debidas a deformaciones elásticas en las roscas y las pérdidas de precarga debidas a falta de perpendicularidad y paralelismo.
