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

Mkulu-mphamvu bawuti kugwirizana ndi kudzera lalikulu kumangitsa kunyezimira bawuti ndodo mkati kugwirizana mbale mbale clamping chidutswa, zokwanira kutulutsa kwambiri kukangana, kuti apititse patsogolo umphumphu ndi stiffness kugwirizana, pamene kukameta ubweya, malinga ndi zofunika kwa kapangidwe ndi nkhawa ndi osiyana, akhoza kugawidwa mu mikangano mtundu mkulu mphamvu bawuti kugwirizana ndi mkulu mphamvu bawuti kugwirizana ndi mkulu mphamvu bawuti kugwirizana ndi mtundu wosiyana wa mphamvu ziwiri, kulumikiza awiri amphamvu kusiyana ndi ofanana ndi malire amphamvu awiri, kulumikiza awiri amphamvu cholumikizira ndi boma lofanana awiri. Mtundu wa bawuti, koma njira yowerengera, zofunikira, kuchuluka kwa ntchito ndizosiyana kwambiri. Mu kapangidwe ka kukameta ubweya, kulumikizidwa kwamphamvu kwambiri kwa bawuti kumatanthawuza mphamvu yolimba ya bawuti yomwe ingaperekedwe ndi mphamvu yolimba ya bawuti pakati pa mphamvu yakumeta ubweya wakunja ndi malo olumikizirana a mbale monga malire, ndiko kuti, kuonetsetsa kuti mphamvu yakumeta ubweya wamkati ndi yakunja ya kugwirizana sikudutsa nthawi yolumikizana sikudutsa nthawi yolumikizira. kupindika kwa mbale (chopanda choyambirira pakati pa wononga ndi khoma la dzenje nthawi zonse chimasungidwa) Mwachidule, ma bawuti amphamvu kwambiri amtundu wa mikangano ndi ma bolts amphamvu kwambiri ndi mtundu womwewo wa mabawuti, koma kapangidwe kake ndi kofananako.
Kutsetsereka sikuganiziridwa.Bolt yamphamvu kwambiri yamtundu wa friction simatha kutsetsereka, bawuti sikhala ndi mphamvu yakumeta ubweya, ikangotsetsereka, kapangidwe kake kamafikira pakulephera, kukhwima muukadaulo;Mabawuti othamanga kwambiri amatha kutsetsereka, ndipo mabawutiwo amakhala ndi mphamvu yakumeta 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. The makina katundu ndi mawerengedwe a bawuti wamba ndi mkulu-mphamvu bawuti ndi osiyana.Kupsyinjika kwa bawuti mkulu-mphamvu ndi choyamba mwa kugwiritsa ntchito pretension P mkati mwake, ndiyeno kukana kukangana pakati pa kukhudzana pamwamba pa chidutswa cholumikizira kunyamula katundu wakunja, ndi kunyamula katundu wamba mwachindunji.

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 chachikulu ndi kulamulidwa kunamiziridwa, kudzera nati ndi mbale, kuti chilumikizidwe ndi kuchuluka kwa prepressure. 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 olumikizana ndi magawo olumikizirana kuti tipewe kutsetsereka. Kuti mukhale ndi mphamvu yolimbana yokwanira pamagulu okhudzana, m'pofunika kuwonjezera mphamvu ya clamping ndi friction coefficient ya malo okhudzana ndi mamembala.
Pakulumikiza kwa bawuti yamphamvu kwambiri, kugundana kwamphamvu kumakhudza kwambiri mphamvu yonyamula.Kuyesa kukuwonetsa kuti kugundana kwamphamvu kumakhudzidwa makamaka ndi mawonekedwe a kukhudzana ndi zinthu za component.
