ʻO ka mea mua, e nānā kākou i ke ʻano o nā wili kaʻa a me kā lākou hana.E pili ana nā ʻūla huila i nā ʻūlū i hoʻokomo ʻia ma ka huila huila a hoʻohui i ka huila, ka disc brake (pahū pahu) a me ka huila huila.ʻO kāna hana ʻo ia ka hoʻopili pono ʻana i nā huila, nā disc brake (pahū pahu) a me nā hubs.E like me kā mākou e ʻike ai, ʻo ke kaumaha o ke kaʻa e kau ʻia e nā huila, no laila e loaʻa ai ka pilina ma waena o nā huila a me ke kino ma o kēia mau wili.No laila, ke kaumaha maoli nei kēia mau kaʻa kaʻa i ke kaumaha o ke kaʻa holoʻokoʻa, a ke hoʻouna pū nei hoʻi i ka torque output mai ka pahu pahu i nā huila, e pili ana i ka hana pālua o ka ʻāʻī a me ka ikaika shear i ka manawa like.
He mea maʻalahi loa ke ʻano o ka wili kaʻa, kahi i haku ʻia me ka ʻūlū, ka nut a me ka mea holoi.E like me nā ʻano hana ʻokoʻa ʻokoʻa, hiki ke hoʻokaʻawale ʻia i nā bolts poʻo hoʻokahi a me nā bolts ʻelua.ʻO ka hapa nui o nā kaʻa o kēia manawa he mau poʻo poʻo hoʻokahi, a hoʻohana mau ʻia nā bolts ma nā kaʻa liʻiliʻi a me nā kaʻa liʻiliʻi.ʻElua mau ala hoʻonohonoho no nā bolts poʻo hoʻokahi.ʻO ka hub bolt + nut kekahi.Hoʻopaʻa ʻia ka bolt ma ka hub me kahi kūpono hoʻopilikia, a laila hoʻopaʻa ʻia ka huila e ka nut.ʻO ka maʻamau, hoʻohana nui ʻia nā kaʻa Iapana a me Korea, a hoʻohana pū ka hapa nui o nā kaʻa.keia ala.ʻO ka pōmaikaʻi o kēia ʻano hana ʻoi aku ka maʻalahi o ka ʻimi ʻana i ka huila, ʻoi aku ka maʻalahi o ka wehe ʻana a me ka hui ʻana o ka huila, a ʻoi aku ka kiʻekiʻe o ka palekana.ʻO ka hemahema, ʻoi aku ka paʻakikī o ka hoʻololi ʻana i nā wili huila, a pono kekahi e wehe i ka huila huila;Hoʻopili pololei ʻia ka wili huila ma ka huila huila, ka mea maʻamau i hoʻohana 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 hoʻololi i nā wili kaila.ʻO ka hemahema, ʻoi aku ka maikaʻi o ka palekana.Inā hoʻokaʻawale pinepine ʻia a hoʻokomo ʻia nā wili kaʻa, e pōʻino nā kaula ma ka hub, no laila pono e hoʻololi ʻia ka hub.
Hana ʻia nā wili kaʻa kaʻa me ke kila ikaika.Paʻi ʻia ka māka ikaika o ka wili ma ke poʻo o ka wili huila.He 8.8, 10.9, a me 12.9.ʻO ka nui o ka waiwai, ʻoi aku ka kiʻekiʻe o ka ikaika.Maʻaneʻi, 8.8, 10.9, a me 12.9 e pili ana i ka lepili papa hana o ka bolt, nona nā helu ʻelua, e hōʻike ana i ka waiwai ikaika tensile nominal a me ka ratio 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 papa hana 8.8 he 800MPa, ʻo ka ratio hua he 0.8, a ʻo ka ikaika o ka hoʻoulu ʻana he 800×0.8=640MPa;ʻO ka ikaika tensile o nā bolts me ka papa hana 10.9 ʻo 1000MPa, ʻo ka lākiō hua he 0.9, a ʻo ka ikaika o ka hāʻawi ʻana he 1000 × 0.9 = 900MPa
ʻO nā mea ʻē aʻe a pēlā aku.ʻO ka mea maʻamau, ʻo ka ikaika o 8.8 a ma luna, ʻo ka mea bolt he haʻahaʻa carbon alloy steel a i ʻole ke kila kalapona waena, a ua kapa ʻia ka lāʻau wela i ka ikaika kiʻekiʻe.ʻO nā wili huila o ke kaʻa he mau wili ikaika kiʻekiʻe.Loaʻa i nā ʻano hoʻohālike like ʻole a me nā ukana like ʻole ka ikaika o ka bolt like ʻole.ʻO 10.9 ka mea maʻamau, 8.8 i hoʻohālikelike ʻia me nā hiʻohiʻona haʻahaʻa, a ʻo 12.9 ka mea maʻamau i nā kaʻa kaumaha.luna.
