GB\/T 3098.4, ba\u011flant\u0131 elemanlar\u0131 i\u00e7in ince di\u015fli somunlar\u0131n mekanik \u00f6zelliklerini belirten bir \u00c7in ulusal standard\u0131d\u0131r. Bu standart, ince di\u015fli somunlar i\u00e7in i\u015faretleme sistemlerini, malzemeleri ve mekanik performans gereksinimlerini kapsayarak c\u0131vata, vida ve saplamalarla uyumlulu\u011fu sa\u011flar. Tan\u0131mlanan nominal y\u00fcksekliklere ve etkili di\u015f uzunluklar\u0131na sahip somunlar i\u00e7in ge\u00e7erlidir ve mekanik montajlarda g\u00fcvenilirli\u011fi garanti etmek i\u00e7in performans s\u0131n\u0131flar\u0131na odaklan\u0131r.

Puanlama Sistemi<\/h2>\n

GB\/T 3098.4 standard\u0131ndaki i\u015faretleme sistemi, somunlar\u0131 nominal y\u00fcksekliklerine ve etkili di\u015f uzunluklar\u0131na g\u00f6re ay\u0131rt eder.<\/p>\n

3.1 Nominal Y\u00fcksekli\u011fi \u2265 0,8D Olan Somunlar (Etkin Di\u015f Uzunlu\u011fu \u2265 0,6D)<\/h3>\n

Bu somunlar, uyumlu olduklar\u0131 c\u0131vata performans s\u0131n\u0131f\u0131n\u0131n ilk rakam\u0131 kullan\u0131larak i\u015faretlenir ve Tablo 2'den en y\u00fcksek uyumlu s\u0131n\u0131f se\u00e7ilir. Daha y\u00fcksek performans s\u0131n\u0131f\u0131na sahip somunlar genellikle daha d\u00fc\u015f\u00fck olanlar\u0131n yerine kullan\u0131labilir. C\u0131vata-somun tertibatlar\u0131, c\u0131vatan\u0131n akma veya dayan\u0131m geriliminin \u00fczerindeki gerilmelere dayanabilir.<\/p>\n

C\u0131vata k\u0131r\u0131lmas\u0131, kademeli s\u0131yr\u0131lman\u0131n aksine, ani ve tespit edilebilir oldu\u011fu i\u00e7in tercih edilir. 8 ila 39 mm aras\u0131ndaki di\u015fler i\u00e7in, Tablo 2'ye g\u00f6re uygun somun se\u00e7imi, c\u0131vatan\u0131n dayan\u0131m y\u00fck\u00fcnde s\u0131yr\u0131lma olmamas\u0131n\u0131 sa\u011flar.
