Ingabe unesifiso sokwazi ngezakhiwo ezingavamile zebanga le-12.9i-allen bolt, eyaziwa nangokuthi i-bolt eyenziwe ngokwezifiso eqine kakhulu? Ake sihlole izici ezichazayo kanye nezinhlelo zokusebenza eziguquguqukayo zale ngxenye emangalisayo.
I-allen bolt yebanga elingu-12.9, evame ukuqashelwa ngombala wayo omnyama wemvelo ohlukile kanye nokuphela kwayo okugcotshwe ngamafutha, ingeyesigaba se-amabhawodi aqine kakhuluLawa mabholthi ngokuvamile enziwa ngensimbi futhi abonisa izilinganiso zokusebenza ezisukela ku-3.6 kuya ku-12.9, enikeza izinketho eziningi zamandla ezidingweni ezahlukahlukene zezimboni.
I-allen bolt yebanga lika-12.9, ikakhulukazi, isetshenziswa kabanzi ezindaweni ezidinga ukusebenza okuphezulu kwemishini. Izimboni ezifana nemishini yokubumba umjovo, imishini ye-hydraulic, kanye nezinhlangano zesikhunta zivame ukuthembela ekuqineni nasekuqineni kwala mabhulothi. Okuphawulekayo ukuthi ubulukhuni bomphezulu we-allen bolt yebanga lika-12.9 ephathwa ngokushisa bungafinyelela ku-39-44 HRC emangalisayo, okuqinisekisa ukusebenza kahle ngaphansi kwezimo ezidinga amandla.
Kubalulekile ukuqaphela ukuthi ikhanda le-allen bolt yebanga le-12.9 liza ne-knurling noma ngaphandle kwayo. Ngokuvamile, ikhanda eligoqiwe lisho i-bolt yebanga le-12.9, kuyilapho lawo angena-knurling engaphansi kwezigaba zamandla aphansi, njengebanga le-4.8. Lo mehluko unikeza ukucaca lapho ukhetha okufanele.ibholithikwezicelo ezithile, ukuqinisekisa ukuthembeka nokuphepha ezimweni ezahlukene zobunjiniyela.
Ama-bolt ethu e-allen angu-12.9 grade anezinzuzo eziningi, okuhlanganisa nomklamo wawo oyingqayizivele wekhanda eliyi-hexagonal. Lesi sici sokuklama sivumela i-torque enkulu ngesikhathi sokufakwa nokuqina, okwenza la ma-bolt afaneleke kakhulu ekusebenzeni kokuhlanganiswa okunembile nokunamandla aphezulu, ikakhulukazi ezindaweni ezivalekile.
Ngaphezu kwalokho, ukwakheka kwesakhiwo se-allen bolt kunikeza ukumelana okuthuthukisiwe kokushelela, okuqinisekisa ukuxhumana okuphephile nokuzinzile ngesikhathi sokufakwa noma ukuqaqwa. Lesi sici senza i-allen bolt isebenze kahle kakhulu kumaphrojekthi anezidingo zamandla eziqinile, okunikeza ukuxhumana okuqinile nokuthembekile.
Ngaphezu kwalokho, i-allen bolt ivame ukubonisa ukumelana okuqinile kokugqwala, okwenza ifaneleke ezindaweni zangaphandle noma ezigqwala kakhulu. Leli khwalithi libeka i-allen bolt njengokukhetha okuthembekile kokusetshenziswa isikhathi eside, ikakhulukazi ezimweni ezidinga ukuvikelwa okwengeziwe kwe-bolt.
Ekuphetheni, i-allen bolt yebanga elingu-12.9 imelela ukuhlanganiswa kwamandla, ukunemba, kanye nokuqina, okwenza kube yingxenye ebalulekile kuzo zonke izinhlobo zezimboni. Ukusebenza kwayo okuvelele kanye nokuzivumelanisa nezimo kugcizelela indima yayo ebalulekile ekwenzeni lula ukwakhiwa okuqinile nokuhlala isikhathi eside.
