Mkulu-mphamvu bawuti kugwirizana ndi kudzera lalikulu kumangitsa kunamizira bawuti ndodo mkati kugwirizana mbale mbale clamping chidutswa, zokwanira kubala kwambiri mikangano, kuti patsogolo kukhulupirika ndi kuumitsa kugwirizana, pamene kukameta ubweya, mogwirizana ndi zofunika kwa kapangidwe ndi kupsyinjika ndi zosiyana, akhoza kugawidwa mu mikangano mtundu mkulu mphamvu bawuti kugwirizana ndi mkulu mphamvu bawuti kulumikiza awiri kuthamanga mtundu, ndi kusiyana kofunikira pakati pa zigawo ziwiri malire ndi osiyana, ngakhale ndi mtundu womwewo wa bawuti, koma mawerengedwe njira, zofunikira, kuchuluka kwa ntchito ndizosiyana kwambiri.Mukumeta ubweya wa ubweya, kulumikiza kwamphamvu kwambiri kumatanthawuza mphamvu yothamanga kwambiri yomwe ingaperekedwe ndi mphamvu yolimbitsa bolt pakati pa mphamvu yakumeta ubweya wakunja ndi kukhudzana pamwamba pa mbale ngati malire. boma, ndiko kuti, kuwonetsetsa kuti mkati ndi kunja kukameta ubweya mphamvu ya kugwirizana sikudutsa mphamvu ya mikangano yaikulu pa utumiki wonse.nthawi.Sipadzakhala kuwonongeka kwa mbale (kupanda koyambirira pakati pa wononga ndi khoma la dzenje kumasungidwa nthawi zonse) .Mukumeta ubweya wa ubweya, kugwirizana kwamtundu wapamwamba wa bawuti kumaloledwa mu mphamvu yakumeta ubweya wakunja kumadutsa mphamvu yothamanga kwambiri. , wachibale kutsetsereka pakati kugwirizana mbale mapindikidwe, mpaka bawuti kukhudzana ndi dzenje khoma, ndiye kugwirizana pa bawuti kutsinde kukameta ubweya ndi kukanikiza pa dzenje khoma ndi kukangana pakati pa kukhudzana pamwamba gulu olowa mphamvu, potsiriza kuti kutsinde kukameta ubweya kapena kukanikiza pa Kuwonongeka kwa khoma la dzenje ngakhale kuvomereza kumeta ubweya wa ubweya. Mwachidule, ma bolts amphamvu-mphamvu kwambiri komanso ma bolts amphamvu kwambiri ndi mtundu womwewo wa mabawuti, koma kapangidwe kake ndi kofanana.
Kutsetsereka sikuganiziridwa. Mtundu wa friction wolimba kwambiri samatha, bawuti sikhala ndi mphamvu yakumeta ubweya, ikangotsika, kapangidwe kake kamafikira kulephera, kukhwima muukadaulo; ndi zometa nazonso zimameta ubweya.Kuwonongeka komaliza ndikufanana ndi mabawuti wamba (kumeta ubweya wa bawuti kapena kuphwanya mbale zachitsulo). Malinga ndi momwe amagwiritsidwira ntchito:
Kulumikizana kwa bawuti kwa membala wamkulu wanyumbayo nthawi zambiri kumapangidwa ndi bolt wamphamvu kwambiri.Maboti odziwika amatha kugwiritsidwanso ntchito, mabawuti amphamvu kwambiri sangathe kugwiritsidwanso ntchito.Maboti amphamvu kwambiri amagwiritsidwa ntchito polumikizana kosatha.
Maboti amphamvu kwambiri ndi ma bolts prestressed, mtundu wa mikangano wokhala ndi torque wrench kuti agwiritse ntchito prestress yomwe idayikidwa, mtundu woponderezedwa wopondereza pamutu wa maula.Maboti wamba amakhala ndi vuto la kumeta ubweya ndipo angagwiritsidwe ntchito m'magawo achiwiri.
Ma bawuti wamba amakhala kalasi 4.4, kalasi 4.8, kalasi 5.6 ndi kalasi 8.8.Mabawuti olimba kwambiri nthawi zambiri amakhala 8.8 ndi 10.9, omwe 10.9 ndi ambiri.
8.8 ndi kalasi yofanana ndi 8.8S.Makina amakina ndi njira zowerengera za bawuti wamba ndi bawuti wamphamvu kwambiri ndizosiyana.Kupsinjika kwa bawuti yamphamvu kwambiri ndikoyamba mwa kugwiritsa ntchito pretension P mkati mwake, ndiyeno kukaniza kukaniza pakati kukhudzana pamwamba pa kulumikiza chidutswa kunyamula katundu kunja, ndi bawuti wamba mwachindunji kunyamula katundu kunja.
Kulumikizana kwakukulu kwa bawuti kuli ndi ubwino wa zomangamanga zosavuta, ntchito yabwino yamakina, yosasunthika, kukana kutopa, komanso pansi pa mphamvu yamphamvu, yomwe ndi njira yolumikizira yodalirika kwambiri.
Mkulu mphamvu bawuti ndi kugwiritsa ntchito wrench wapadera kumangitsa nati, kotero kuti bawuti kubala yaikulu ndi ankalamulira kudziyerekezera, kudzera nati ndi mbale, kuti chilumikizidwe ndi kuchuluka chomwecho prepressure. , mphamvu yothamanga kwambiri idzapangidwira pamwamba pa chidutswa cholumikizidwa.Mwachiwonekere, malinga ngati mphamvu ya axial ili yochepa kuposa mphamvu yotsutsanayi, membalayo sangatengeke ndipo kugwirizana sikudzawonongeka.Iyi ndiye mfundo yolumikizira bolt yamphamvu kwambiri.
Kulumikizana kwakukulu kwa bawuti kumadalira mphamvu yakukangana pakati pa malo olumikizirana ndi magawo olumikizirana kuti tipewe kutsetsereka.Kuti mukhale ndi mphamvu yolimbana yokwanira pamalo olumikizana, ndikofunikira kuwonjezera mphamvu yolumikizirana ndi mikangano yolumikizana ndi mamembala. kukhala opangidwa ndi zitsulo zamphamvu kwambiri, chifukwa chake amatchedwa maulumikizidwe amphamvu kwambiri.
Pakulumikizana kwakukulu kwa bolt, kugundana kwamphamvu kumakhudza kwambiri mphamvu yonyamula.Kuyesa kukuwonetsa kuti kugundana kwamphamvu kumakhudzidwa makamaka ndi mawonekedwe amtundu wa kukhudzana ndi zinthu za component. , njira monga kuphulika kwa mchenga ndi kuyeretsa mawaya burashi nthawi zambiri ntchito pomanga kuchitira kukhudzana pamwamba pa zigawo zikuluzikulu mkati kugwirizana osiyanasiyana.
