ʻO ka mea mua, e nānā kākou i ke ʻano o nā wili huila a me kā lākou hana. ʻO nā wili huila e pili ana i nā wili i hoʻokomo ʻia ma ke kikowaena huila a hoʻohui i ka huila, ka disc brake (pahu brake) a me ke kikowaena huila. ʻO kāna hana ka hoʻohui pono ʻana i nā huila, nā disc brake (pahu brake) a me nā kikowaena. E like me kā kākou e ʻike nei, ʻo ke kaumaha o ke kaʻa e hāpai ʻia e nā huila, no laila ua hoʻokō ʻia ka pilina ma waena o nā huila a me ke kino ma o kēia mau wili. No laila, ʻo kēia mau wili huila ke hāpai nei i ke kaumaha o ke kaʻa holoʻokoʻa, a hoʻoili pū i ka torque output mai ka pahu pahu i nā huila, kahi i kau ʻia i ka hana pālua o ka tension a me ka shear force i ka manawa like.
He maʻalahi loa ke ʻano o ka wili huila, nona ka wili, ka nati, a me ka mea holoi. Wahi a nā ʻano wili like ʻole, hiki ke hoʻokaʻawale ʻia i nā wili poʻo hoʻokahi a me nā wili poʻo pālua. ʻO ka hapa nui o nā kaʻa o kēia manawa he mau wili poʻo hoʻokahi, a hoʻohana pinepine ʻia nā wili stud ma nā kalaka liʻiliʻi a me waena. ʻElua mau ʻano hoʻonohonoho no nā wili poʻo hoʻokahi. ʻO kekahi he wili hub + nati. Hoʻopaʻa ʻia ka wili ma ke kikowaena me kahi kūpono hoʻopilikia, a laila hoʻopaʻa ʻia ka huila e ka nati. Ma ke ʻano laulā, hoʻohana nui ʻia nā kaʻa Kepanī a me Kōlea, a hoʻohana pū ka hapa nui o nā kalaka iā ia. ma kēia ʻano. ʻO ka pōmaikaʻi o kēia ʻano hana, ʻoi aku ka maʻalahi o ka loaʻa ʻana o ka huila, ʻoi aku ka maʻalahi o ka wehe ʻana a me ka ʻākoakoa ʻana o ka huila, a ʻoi aku ka kiʻekiʻe o ka palekana. ʻO ka hemahema, ʻoi aku ka pilikia o ka hoʻololi ʻana i nā wili huila, a pono kekahi e wehe i ke kikowaena huila; Hoʻopaʻa pololei ʻia ka wili huila ma ke kikowaena huila, kahi i hoʻohana nui ʻia i nā kaʻa liʻiliʻi ʻEulopa a me ʻAmelika. ʻO ka pōmaikaʻi o kēia ʻano hana, ʻoi aku ka maʻalahi o ka wehe ʻana a me ka hoʻololi ʻana i nā wili huila. ʻO ka hemahema, ʻoi aku ka ʻino o ka palekana. Inā wehe pinepine ʻia a hoʻokomo ʻia nā wili o ka huila, e hōʻino ʻia nā kaula ma ka hub, no laila pono e hoʻololi ʻia ka hub.
Hana ʻia nā wili o nā huila kaʻa me ke kila ikaika kiʻekiʻe. Ua paʻi ʻia ka pae ikaika o ka wili ma ke poʻo o ka wili huila. Aia he 8.8, 10.9, a me 12.9. ʻO ka nui o ka waiwai, ʻo ka kiʻekiʻe o ka ikaika. Maanei, ʻo 8.8, 10.9, a me 12.9 e pili ana i ka lepili pae hana o ka bolt, nona nā helu ʻelua, e hōʻike ana i ka waiwai ikaika tensile nominal a me ka lakio hua o ka mea bolt, i hōʻike pinepine ʻia e "XY", e like me 4.8, 8.8, 10.9, 12.9 a pēlā aku. ʻO ka ikaika tensile o nā bolts me ka pae hana 8.8 he 800MPa, ʻo ka lakio hua he 0.8, a ʻo ka ikaika hua he 800 × 0.8 = 640MPa; ʻO ka ikaika tensile o nā bolts me ka papa hana 10.9 he 1000MPa, ʻo ka lakio hua he 0.9, a ʻo ka ikaika hua he 1000 × 0.9 = 900MPa
ʻO nā mea ʻē aʻe a pēlā aku. Ma keʻano laulā, ʻo ka ikaika o 8.8 a ʻoi aku, ʻo ka mea hoʻopaʻa he kila hao kalapona haʻahaʻa a i ʻole ke kila kalapona waena, a ua kapa ʻia ka mālama wela he bolt ikaika kiʻekiʻe. ʻO nā wili huila o ke kaʻa he mau bolt ikaika kiʻekiʻe. Loaʻa i nā ʻano hoʻohālike like ʻole a me nā ukana like ʻole nā ikaika bolt kūlike. ʻO 10.9 ka mea maʻamau, ʻo 8.8 ka mea maʻamau i hoʻohālikelike ʻia i nā ʻano hoʻohālike haʻahaʻa, a ʻo 12.9 ka mea maʻamau i hoʻohālikelike ʻia i nā kalaka kaumaha. ʻoi aku ka maikaʻi.
