Kugwiritsa ntchito bwino kwa 10.9S bawuti yayikulu ya hex mumakampani? 

Mukuwona macheza ambiri pa intaneti okhudza mabawuti amphamvu kwambiri, koma zikafika pakugwiritsa ntchito 10.9S lalikulu hex bolt seti, pamakhala chisokonezo chodabwitsa. Anthu nthawi zambiri amangoganiza zolimba, ntchito zolemetsa ndikuwamenya kulikonse. Chowonadi ndi chosasinthika. Gulu la 10.9S ndilolonjezano lachindunji-kuchepera 1000 MPa mphamvu zowonongeka, mphamvu zosachepera 900 MPa zokolola, ndi 'S' zomwe zimasonyeza kukula kwa M12 ndi pamwamba. Mutu wawukulu wa hex ndiye fungulo la torque yayikulu yofunikira kuti mukwaniritse mphamvu yochepetsera yomwe idapangidwa. Kugwiritsa ntchito molakwika nthawi zambiri sikukhudza bawuti kulephera kukangana; ndi za kutsetsereka kwa olowa, kutopa, kapena hydrogen embrittlement chifukwa wina amachitenga ngati chinthu cha sitolo yamagetsi.

Filosofi Yachikulu: Ndi Yogwirizana, Osati Bolt Yokha

Iwalani bawuti kwa kamphindi. Mukupanga kapena kukonza a kugwirizana kwamphamvu. Ndilo gawo loyamba la ma seti akulu akulu a 10.9S awa. Ganizirani zolumikizira zachitsulo, zoyambira zamakina olemera, kapena kulumikizana ndi turbine flange. Ntchito ya bawuti ndikumangirira mbale molimba kwambiri kotero kuti katunduyo amasamutsidwa ndi kukangana pakati pa mbale, osati kumeta ubweya pa shank ya bawuti. Ngati mukuwagwiritsa ntchito polumikizana ndi kukameta ubweya komwe thupi la bawuti limalimbana ndi dzenje, mwina mumangofotokoza mopitilira muyeso ndikuwononga ndalama, pokhapokha ngati kutsitsa kwamphamvu ndichinthu chachikulu.

Ndikukumbukira pulojekiti yobwezeretsanso pamapangidwe othandizira othandizira. Zolemba zoyambirira zimafuna ma bolt 8.8, koma kugwedezeka kunali kupangitsa kuti mgwirizano usungunuke. Tinasinthira ku seti ya 10.9S yokhala ndi ma torque ovomerezeka. Kusiyanitsa sikunali kukweza kwapamwamba; mutu wokulirapo wa hex udatilola kugwiritsa ntchito ma wrenches olondola kwambiri a hydraulic torque, kuwonetsetsa kuti ma bawuti onse azikhala osasinthasintha. Kumasula kunasiya. Phunziro linali lakuti bawuti-kuphatikiza zotsukira zolimba zolimba - zidathandizira njira yokhazikika, osati gawo lolimba.

Ma washers sangakambirane. Muyenera kugwiritsa ntchito makina ochapira olimba pansi pa mutu wa bawuti ndi mtedza. Kudzaza kwambiri kumatha kukumba ndikusintha ma washer wamba (kapena zinthu zolumikizidwa), kuchepetsa mphamvu yoletsa. Ichi ndi cholakwika chatsamba chomwe ndachiwonapo: ma bolts okhazikika, koma ochapira ofewa, osasinthika, zomwe zimapangitsa kuti ntchito yonse ikhale yopanda tanthauzo. Seti ndi ndondomeko.

Kumene Amawala: Makina Olemera ndi Ntchito Zamapangidwe

Zipangizo zamigodi ndi zoyendetsa dziko lapansi ndi nkhani yamabuku. Ulalo wa track ya excavator, maulalo a ndowa zonyamula, maphwando amtundu wa crusher. Izi ndi zolumikizana zolimba kwambiri zomwe zimatha kugwedezeka kwambiri, mosinthasintha. Seti yayikulu ya hex ya 10.9S, yoyikidwa bwino, imasunga kulimba kwamagulu, komwe ndikofunikira pakulumikizana kwa zigawo ndi moyo wotopa. Mutu wawukulu wa hex ndi wofunikira pano - umayimilira kubwereza, kupweteketsa kwambiri panthawi yokonza munda popanda kuzungulira.

M'zitsulo zomangidwa kale, monga zotengera zosungiramo katundu kapena pansi pa mezzanine, zimagwiritsidwa ntchito polumikizana kwakanthawi kapena m'malo ovuta. Ubwino wopitilira kuwotcherera ndi kulosera, kulowetsedwa kosawoneka bwino. Mutha kuwayang'ana ndi wrench ya torque pakuwunika.
