Ukuthwala umthamo = amandla x indawo
I-Bolt ine-screw thread, i-M24 bolt indawo yecandelo lomnqamlezo ayikho indawo yesangqa se-24, kodwa i-353 square mm, ebizwa ngokuba yindawo esebenzayo.
Amandla obunzima beebholiti eziqhelekileyo zeklasi C (4.6 kunye ne-4.8) yi-170N / sq. mm
Emva koko umthamo wokuthwala: 170×353 = 60010N.
Ngokutsho koxinzelelo loxhumo: ihlulwe ibe yimingxuma eqhelekileyo kunye ne-hinged.Ngemilo yentloko ngesenti: yiba nentloko enehexagon, intloko engqukuva, intloko eyisikweri, intloko etshonelweyo njalo njalo.Intloko yeHexagon yeyona isetyenziswa kakhulu.Intloko ye-countersunk idla ngokusetyenziswa apho kufuneka uxhulumaniso
Riding bolt IsiNgesi igama i-u-bolt, iindawo non-standard, imilo u-shaped ngoko ke yaziwa ngokuba ibholithi u-ezimilise, zombini iziphelo intambo inokudityaniswa kunye nut, ikakhulu isetyenziselwa ukulungisa ityhubhu ezifana umbhobho wamanzi okanye ipleyiti efana nomthombo wemoto, ngenxa yendlela yokulungisa izinto njengabantu abakhwele amahashe, okubizwa ngokuba yi-riding bolt.Ngokobude bomsonto ube ngumsonto opheleleyo kwaye ungeyo-intambo epheleleyo iindidi ezimbini.
Ngokomsonto wamazinyo ahlulwe abe ziindidi ezibini zamazinyo arhabaxa kunye namazinyo acolekileyo, amazinyo arhabaxa kwiibholiti awabonisi.Iibholithi zihlelwe zibe yi-3.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9 kunye ne-12.9 ngokwebakala lokusebenza.Iibholiti ezingaphezulu kwe-8.8 grade (kubandakanywa ne-8.8 grade) zenziwe ngentsimbi ephantsi ye-carbon alloy okanye i-medium carbon steel kwaye ziye zafumana unyango lobushushu (ukucima kunye nokufudumala).Ngokuqhelekileyo zibizwa ngokuba yi-high-strength bolts kwaye ngaphantsi kwe-8.8 grade (ngaphandle kwe-8.8 grade) zibizwa ngokuba ziibholiti eziqhelekileyo.
Iibholiti eziqhelekileyo zinokwahlulwa zibe ngamabakala A, B kunye no-C ngokuchaneka kwemveliso.Amabanga A kunye no-B ziibholiti ezicolisisiweyo kwaye amabakala C azibholithi ezirhabaxa.Kwiibholiti zokudityaniswa kwesakhiwo sentsimbi, ngaphandle kokuba kuphawulwe ngokukodwa, ngokubanzi iibholithi ezirhabaxa zeklasi C eziqhelekileyo
