Introduzione allo standard GB\/T 3098.10<\/h2>\n

Questa norma specifica le propriet\u00e0 meccaniche dei dadi autobloccanti in acciaio a coppia prevalente, garantendo la resistenza alle vibrazioni nelle applicazioni di fissaggio. \u00c8 conforme alla norma ISO 2320-2015 per i metodi di prova, coprendo le classi 04, 05, 5, 6, 8 e 10. Una selezione e una prova adeguate mantengono l'integrit\u00e0 dell'assemblaggio sotto carichi dinamici.<\/p>\n<\/div>\n

\n

Ambito di applicazione<\/h2>\n

La norma GB\/T 3098.10-1993 definisce i requisiti prestazionali per i dadi autobloccanti in acciaio con caratteristiche di coppia di serraggio prevalente, applicabili alle misure da M5 a M39 con passo grosso e fine. Include prove di forza di serraggio e di coppia di serraggio prevalente per verificare l'efficacia del bloccaggio, risultando adatta a settori come quello automobilistico e meccanico, dove la prevenzione dell'allentamento \u00e8 fondamentale.<\/p>\n

    \n
  • Applicabile a dadi di bloccaggio con inserto interamente in metallo e non metallico.<\/li>\n
  • Garantisce una coppia di serraggio costante anche dopo numerose installazioni\/rimozioni.<\/li>\n
  • Per i carichi di prova e i coefficienti di attrito, fare riferimento alla norma ISO 898-2.<\/li>\n<\/ul>\n<\/div>\n
    \n

    Metodi e requisiti di prova<\/h2>\n

    I test valutano la forza di serraggio sotto carichi specificati e misurano la coppia prevalente durante i cicli di installazione e rimozione. La forza di serraggio \u00e8 pari a 80% del carico di prova del dado, con limiti a 75% e 65% per la valutazione dell'attrito. Utilizzare il controllo statistico di processo per la valutazione, indipendentemente dalla statistica.<\/p>\n

      \n
    1. Applicare la forza di serraggio di prova F80<\/sub>.<\/li>\n
    2. Misurare la coppia di serraggio per la prima installazione (valore massimo per componenti interamente in metallo; 50% per inserti).<\/li>\n
    3. Valutare le coppie di serraggio per la prima e la quinta rimozione (valori minimi).<\/li>\n<\/ol>\n

      Questi accorgimenti assicurano che i dadi rimangano bloccati senza attrito eccessivo o danni.<\/p>\n<\/div>\n

      \n

      Dadi a coppia prevalente Classe 04<\/h2>\n

      Per i dadi di classe 04 (5 mm \u2264 d \u2264 39 mm), la forza di serraggio \u00e8 pari al carico di prova 80% secondo ISO 898-2. I limiti valutano il coefficiente di attrito totale \u03bclotto<\/sub>.<\/p>\n

      Domande frequenti<\/h2>\n

      Qual \u00e8 lo scopo della coppia di serraggio prevalente nei dadi di bloccaggio?<\/h3>\n

      Offre resistenza all'allentamento dovuto alle vibrazioni, misurata attraverso cicli di installazione e rimozione per garantire prestazioni costanti.<\/p>\n

      In che modo la classificazione differisce tra dadi con inserto interamente in metallo e dadi con inserto non metallico?<\/h3>\n

      Per gli inserti non metallici, la coppia massima di serraggio per la prima installazione \u00e8 di 50% rispetto ai valori indicati, al fine di evitare di danneggiare l'inserto.<\/p>\n

      Cosa succede se la coppia scende al di sotto del valore minimo dopo la quinta rimozione?<\/h3>\n

      Il dado non supera il test; selezionare una classe superiore o verificare le condizioni di montaggio, come la lubrificazione e la corretta filettatura.<\/p>\n

      Come si calcolano i limiti della forza di serraggio?<\/h3>\n

      Superiore: 75% di carico di prova; inferiore: 65%. Da utilizzare per la valutazione del coefficiente di attrito nel controllo qualit\u00e0.<\/p>\n

      Questi valori si applicano solo ai toni fini?<\/h3>\n

      No, le tabelle includono sia la filettatura grossa che quella fine; assicurarsi che le specifiche della filettatura corrispondano per una prova accurata.<\/p>\n

      Quali norme fanno riferimento ai carichi di prova?<\/h3>\n

      Norme ISO 898-1\/2 o GB\/T 3098.1 per i carichi di bulloni\/dadi, garantendo la compatibilit\u00e0 negli assemblaggi.<\/p>\n<\/div>\n
