Kusiyana kwa mtundu wa mikangano yayikulu ya bawuti ndi kulumikizana kwamtundu wa kuthamanga

Mkulu-mphamvu bawuti kugwirizana ndi kudzera lalikulu kumangitsa kunamizira bawuti ndodo mkati kugwirizana mbale mbale clamping chidutswa, zokwanira kubala kwambiri mikangano, kuti patsogolo umphumphu ndi kuumitsa kugwirizana, pamene kukameta ubweya, mogwirizana ndi zofunika kwa kapangidwe ndi kupsinjika ndi kosiyana, zitha kugawidwa m'magulu okangana amtundu wa bawuti wamphamvu kwambiri komanso bawuti yamphamvu yolumikiza mitundu iwiri yamphamvu, ndiye kusiyana kofunikira pakati pazigawo ziwirizi ndi zosiyana, ngakhale ndi mtundu womwewo wa bawuti, koma kuwerengera 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 yometa ubweya wakunja ndi kukhudzana pamwamba pa mbale ngati malire. boma, ndiko kuti, kuonetsetsa kuti mkati ndi kunja kukameta ubweya mphamvu ya kugwirizana sikudutsa mphamvu yothamanga kwambiri pa nthawi yonse yautumiki.Sipadzakhala kusintha kwachibale kwa mbale (chopanda choyambirira pakati pa wononga ndi dzenje. khoma limasungidwa nthawi zonse) .Mukumeta ubweya wa ubweya, kuthamanga kwamtundu wapamwamba wa bawuti kulumikizidwa kumaloledwa mu mphamvu yakumeta ubweya wakunja kupitilira mphamvu yakukangana kwambiri, kutsetsereka kwa wachibale pakati pa kulumikizidwa kwa mbale, mpaka kukhudzana ndi bawuti ndi khoma la dzenje, kenako kulumikizana Kumeta ubweya wa bolt ndikukankhira pakhoma la dzenje ndi kukangana pakati pa gulu lolumikizana ndi gulu lolumikizana, pomaliza mpaka kukameta ubweya kapena kukakamiza pabowo kuwonongeka kwa khoma ngakhale kuvomereza kumeta ubweya wa malire. mabawuti amphamvu kwambiri amakhala amtundu womwewo, koma mapangidwe ake ndi
Slippage saganiziridwa. Mtundu wa friction wolimba kwambiri samatha, bawuti silikhala 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 yokhala ndi torque wrench kuti agwiritse ntchito prestress yomwe yaperekedwa, mtundu wapanikizi wochotsa pamutu wa maula.Maboti wamba amakhala ndi vuto lometa ubweya ndipo angagwiritsidwe ntchito m'magawo achiwiri.Maboti wamba amangofunika kumangirizidwa.
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 opangira makina ndi njira zowerengera za bawuti wamba ndi bawuti yamphamvu kwambiri ndizosiyana.Kupsinjika kwa bawuti yamphamvu kwambiri ndikoyamba mwa kugwiritsa ntchito pretension P mkati mwake, ndiyeno kukaniza kukaniza pakati kukhudzana pamwamba pa chidutswa cholumikizira kunyamula katundu kunja, ndi bawuti wamba ndi 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 lalikulu ndi ankalamulira kudziyerekezera, mwa mtedza ndi mbale, kuti chilumikizidwe ndi kuchuluka chomwecho prepressure.Pansi zochita za pre-pressure , mphamvu yothamanga kwambiri idzapangidwira pamwamba pa chidutswa cholumikizidwa. Mwachiwonekere, malinga ngati mphamvu ya axial ili yochepa kuposa mphamvu yotsutsanayi, membalayo sangagwedezeke ndipo kugwirizana sikudzawonongeka. Iyi ndiye mfundo yolumikizira bolt yamphamvu kwambiri.
Kulumikizana kwakukulu kwa bawuti kumadalira mphamvu yakukangana pakati pa malo olumikizana 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 kwamphamvu kwambiri kwa bolt, kugundana kwamphamvu kumakhudza kwambiri mphamvu yonyamula.Kuyesa kukuwonetsa kuti kugundana kwamphamvu kumakhudzidwa makamaka ndi mawonekedwe a kukhudzana ndi zinthu za component. , Njira monga kuphulika kwa mchenga ndi kuyeretsa burashi ya waya nthawi zambiri zimagwiritsidwa ntchito pomanga kuti zithetse kukhudzana kwa zigawo zomwe zili mkati mwa kugwirizana.
