Nā kikoʻī o nā Bolts ikaika kiʻekiʻe
Wahi a ke kūlana koʻikoʻi, hiki ke hoʻokaʻawale ʻia i ke ʻano friction a me ke ʻano kaomi: ʻOiaʻiʻo, aia nā ʻokoʻa i ka hoʻolālā a me nā ʻano helu.ʻO ke ʻano friction ʻano ikaika kiʻekiʻe e lawe i ka paheʻe ma waena o nā papa e like me ke kūlana palena o ka hiki ke amo.ʻO ke ʻano-I ka ikaika kiʻekiʻe e lawe i ka paheʻe ma waena o nā papa e like me ke kūlana palena maʻamau, a ʻo ka hemahema o ka pilina e like me ke kūlana palena o ka hiki ke amo.ʻAʻole hiki i nā bolts ikaika kiʻekiʻe ke hāʻawi i ka pāʻani piha i ka hiki o nā bolts.Ma ka hoʻohana pono ʻana, pono e hoʻohana ʻia nā kīʻaha ikaika kiʻekiʻe no nā hale koʻikoʻi a i ʻole nā mea hana e lawe ana i nā haʻahaʻa ikaika, ʻoi aku ka nui o ka wā e hoʻihoʻi ʻia ke kaumaha.I kēia manawa, hiki ke hoʻohana ʻia ka hiki ke hoʻohana ʻole ʻia e like me kahi mālama palekana.Eia kekahi, pono e hoʻohana ʻia nā bolts ikaika kiʻekiʻe e hoʻemi i ke kumukūʻai.
Wahi a ka ʻenehana hana, ua māhele ʻia i: torsional shear type kiʻekiʻe ikaika a me hexagonal nui ikaika kiʻekiʻe.ʻO ka pahu ikaika kiʻekiʻe hexagonal no ka māka ikaika kiʻekiʻe o nā wili maʻamau, ʻoiai ʻo ke ʻano torsional shear type high-strength bolt he ʻano hoʻomaikaʻi ʻia o ka bolt ikaika kiʻekiʻe hexagonal, i mea e kūkulu maikaʻi ai.Pono e wili mua ʻia ke kūkulu ʻia ʻana o nā bolts ikaika a ma hope, a ʻo ke ʻano hopena wili uila a i ʻole torque-adjustable wili uila e hoʻohana ʻia no ka wili mua ʻana o nā bolts ikaika kiʻekiʻe;Eia nō naʻe, aia nā koi koʻikoʻi no ka hoʻopaʻa hope ʻana i nā bolts ikaika kiʻekiʻe.ʻO ka hoʻopaʻa hope ʻana o nā ʻāpana torsional ʻano kiʻekiʻe e pono e hoʻohana i kahi wīwī uila ʻano ʻāwīwī, a ʻo ka hoʻopaʻa hope ʻana o nā ʻano torque ʻano ikaika kiʻekiʻe e hoʻohana i kahi torque type uila.Aia ka bolt hexagonal i kahi bolt, kahi nut a me ʻelua mau mea holoi.ʻO ke ʻano shear-type high-strength bolt i loko o kahi pahu, kahi nut a me kahi mea holoi.
1. ʻO ka pahu paʻi ikaika kiʻekiʻe: Hoʻohana nui ʻia kēia ʻano o ka pahu ikaika kiʻekiʻe no ka hoʻopili ʻana ma waena o nā mea hoʻolālā static a i ʻole nā mea hoʻoheheʻe iki.Pono e hoʻohana ʻia ka bolt ikaika kiʻekiʻe no ka hiki ke hoʻoikaika ikaika a me ka pale ʻana i ka shear ikaika.
2. Friction-type high-strength bolt: Hoʻohana nui ʻia kēia ʻano o ka bolt ikaika kiʻekiʻe no ka hoʻopili ʻana ma waena o ka ʻōnaehana braking a me nā hale koʻikoʻi e lawe ana i nā haʻahaʻa ikaika, e like me ka hoʻopili ʻana i nā kaola crane kaumaha a me nā kukuna pūnaewele paʻa.
3. Tensile-type kiʻekiʻe-ikaika bolts: ʻO ke koi kumu o kēia ʻano o nā bolts ikaika kiʻekiʻe, ʻaʻole maʻalahi nā bolts i ka deform, ʻoki a hāʻule paha ma lalo o ka haʻalulu ikaika, a me nā mea ʻē aʻe. ʻāpana.
ʻO nā bolts ikaika kiʻekiʻe e kūpono i nā hale ākea nui, nā hale kila o nā mea kanu ʻoihana, nā hale kila o nā hale kiʻekiʻe, nā alahaka, nā mīkini hāpai kaumaha a me nā hale koʻikoʻi ʻē aʻe.
Wahi a ke ʻano pili, aia nā ʻano ʻekolu:
(1) He kūpono ka hoʻokomo ʻana a me ka holoi ʻana i nā ʻano bolts ikaika kiʻekiʻe no ka hoʻopili ʻana i ke kolamu-kolo i nā hale kila, nā pilina kaola crane kaumaha i nā mea kanu ʻoihana, nā pilina pūnaewele paʻa, nā ʻōnaehana braking a me nā hale koʻikoʻi e halihali ana i nā ukana ikaika.
(2) Hiki ke hoʻohana ʻia nā bolts ikaika kiʻekiʻe no ka hoʻokuʻi ʻana i ka hoʻokuʻi ʻana i nā haʻahaʻa haʻahaʻa static e hiki ai i kahi liʻiliʻi o ka hoʻoheheʻe ʻana a i ʻole nā ʻāpana e amo pono ʻole i nā haʻahaʻa ikaika.
(3) Loaʻa ka ikaika haʻahaʻa haʻahaʻa o nā bolts kiʻekiʻe kiʻekiʻe i ka neʻe ʻana, a ʻaʻole hiki ke maʻalahi ko lākou lawe ʻana ma mua o 0.6P (P ma lalo o ka haʻahaʻa ikaika (P ʻo ia ka ikaika axial o nā bolts). hoʻouka, e like me ka hui pū flange a me ka hui-T o ka pahu hoʻoemi.
