Tsatanetsatane wa High Strength Bolts
Malingana ndi kupsinjika maganizo, zikhoza kugawidwa mumtundu wa mikangano ndi mtundu wa kupanikizika: Kwenikweni, pali kusiyana kwa mapangidwe ndi njira zowerengera.Mitundu ya mikangano yamphamvu yamphamvu kwambiri imatenga kutsetsereka pakati pa mbale ngati malire a mphamvu yobereka.Maboti amphamvu kwambiri a Type-I amatenga slip pakati pa ma slabs ngati malire okhazikika, ndipo kulephera kwa kulumikizana kumakhala ngati malire a mphamvu yonyamula.Mabawuti olimba kwambiri samatha kusewera mokwanira ku kuthekera kwa mabawuti.Pogwira ntchito, mabawuti amphamvu kwambiri amtundu wa mikangano ayenera kugwiritsidwa ntchito pazinthu zofunika kwambiri kapena zokhala ndi katundu wosunthika, makamaka pamene katunduyo amayambitsa kupsinjika.Panthawiyi, mphamvu ya bawuti yosagwiritsidwa ntchito ingagwiritsidwe ntchito ngati malo otetezera.Kuonjezera apo, ma bolts othamanga kwambiri ayenera kugwiritsidwa ntchito kuchepetsa mtengo.
Malingana ndi luso la zomangamanga, lagawidwa kukhala: torsional shear mtundu wamphamvu kwambiri ndi bawuti yaikulu ya hexagonal yamphamvu kwambiri.Bawuti yamphamvu kwambiri ya hexagonal ndi ya zomangira zolimba kwambiri, pomwe bolt yolimba kwambiri yamtundu wa torsional shear ndi mtundu wowongoleredwa wa bawuti yolimba kwambiri ya hexagonal, kuti imange bwino.Kupanga ma bolts amphamvu kwambiri kuyenera kulumikizidwa kaye kenako pomaliza, ndipo mtundu wamagetsi opangira magetsi kapena wrench yamagetsi yosinthira torque iyenera kugwiritsidwa ntchito powombera koyambirira kwa mabawu amphamvu kwambiri;Komabe, pali zofunikira zokhwima zomangirira komaliza kwa ma bolts amphamvu kwambiri.Kumangitsa komaliza kwa ma bawuti amphamvu kwambiri amtundu wa torsional shear ayenera kugwiritsa ntchito wrench yamagetsi yamtundu wa torsional shear, ndipo kulimbitsa komaliza kwa mabawuti amphamvu kwambiri amtundu wa torque ayenera kugwiritsa ntchito wrench yamagetsi yamtundu wa torque.Bawuti ya hexagonal imakhala ndi bawuti, nati ndi ma washer awiri.Bolt yamphamvu kwambiri yamtundu wa shear imakhala ndi bolt, nati ndi makina ochapira.
1. Bolt yokhala ndi mphamvu yayikulu: Mtundu uwu wa bawuti wamphamvu kwambiri umagwiritsidwa ntchito makamaka polumikizana pakati pa zigawo zokhazikika kapena zoyenda pang'ono.Zimafunika kuti bolt yamphamvu kwambiri igwiritsidwe ntchito pa mphamvu yamphamvu yonyamula mphamvu komanso kukana kukameta ubweya wambiri.
2. Bawuti yolimba kwambiri yamtundu wa Friction: Mtundu uwu wa chitsulo champhamvu kwambiri umagwiritsidwa ntchito makamaka polumikizana pakati pa braking system ndi zida zofunika zonyamula katundu wosunthika, monga kulumikizana kwa matabwa olemera a crane ndi matanda olimba a intaneti.
3. Mabotolo amphamvu kwambiri amtundu wamtundu: Chofunikira kwambiri pamtundu uwu wazitsulo zamphamvu kwambiri ndikuti ma bolts sali ophweka kufooketsa, kusweka kapena kugwa pansi pa kupsinjika kwakukulu, ndi zina zotero. magawo.
Maboti amphamvu kwambiri ndi oyenera nyumba zazikuluzikulu, zitsulo zamitengo yamakampani, zida zachitsulo zamitengo yamitengo yapamwamba, zida za mlatho, makina onyamula katundu ndi zida zina zofunika.
Malinga ndi mtundu wolumikizira, pali mitundu itatu iyi:
(1) Kuyika ndi kupukuta ma bawuti amphamvu kwambiri ndi oyenera kulumikizana ndi mizati muzitsulo zamafelemu achitsulo, kulumikizana kwamtengo wa crane m'mafakitale, kulumikizana kolimba kwa matanda a ukonde, ma braking system ndi zida zofunika zonyamula katundu wosunthika.
(2) Maboti amphamvu kwambiri amatha kugwiritsidwa ntchito polumikizira kukameta ubweya m'magawo olemetsa omwe amalola kutsika pang'ono kapena m'zigawo zomwe mosalunjika zimanyamula katundu wamphamvu.
(3) Maboti olimba kwambiri amakhala ndi mphamvu yotopa pang'onopang'ono, ndipo mphamvu yawo yonyamula sichitha kupitirira 0.6P (P pansi pa katundu wamphamvu (P ndi mphamvu yovomerezeka ya axial ya mabawuti). Choncho, ndiyoyenera kugwiritsidwa ntchito pansi pa static katundu, monga cholumikizira cha flange butt ndi T-joint ya compression bar.
