Tabella serraggio bulloni con chiave dinamometrica

Il serraggio di bulloni e tiranteria a coppia controllata è indicato mediante due valori, coppia di serraggio e precarico. Questi valori variano in base a molteplici fattori, diametro del tirante, passo, classe, coefficiente di attrito. Proprio il “COEFFICIENTE di ATTRITO” svolge un ruolo focale nella valutazione dei delle coppie da applicare. Essendo questo elemento molto variabile e di difficile determinazione, le tabelle sottostanti hanno un valore di pura indicazione teorica e lasciamo al progettista il compito di determinare il valore corretto di serraggio per i propri progetti.

 

INDICE TABELLE:

Precarichi e coppie di serraggio – Valori standard

Classi di bulloneria a passo grosso

Questa tabella fornisce i valori standard dei precarichi e delle coppie di serraggio per bulloni utilizzati con chiavi dinamometriche. I dati sono organizzati per classi di bulloneria a passo grosso, indicando le forze di precarico (in Newton) e le coppie di serraggio (in Newton metro) per varie combinazioni di diametri e coefficienti di attrito.
