Fastener torque ndi mavuto wamba

Gawo la maudindo a torque ya fastener

1. PATAC ili ndi udindo wotulutsa torque yamphamvu ndi torque yoyamba yokhazikika.PATAC imatulutsa mulingo wokhazikika wa torque molingana ndi kapangidwe kake, kuphatikizika ndi zotsatira zoyeserera komanso zoyeserera zamsewu.

2. ME ili ndi udindo wotulutsa torque yosasunthika Molingana ndi torque yamphamvu yotulutsidwa ndi PATAC, torque ya chida chomangirira imasinthidwa mu Dzina lachidziwitso cha torque yamphamvu pamzere wopanga.Kenako torque yosasunthika imayesedwa molingana ndi njira yabwinobwino yopangira.Pogwiritsa ntchito njira yowerengera (maseti 30 a data), Nominal ndi kulolerana kwa static torque standard amapezeka, ndipo mulingo wokhazikika wa torque umapezeka.

Ma torque amphamvu komanso mawonekedwe olembera a torque

1. Mphamvu yamphamvu

D dzina +/-kulolera NM;Ma torque amphamvu amalembedwa mwadzina +/ tolerances monga D30 +/-5nm;Palibe danga pakati pa D ndi 30+/-5NM;Pamene D amaimira Mphamvu;NM ndi gawo la torque: Newton.Mamita;kulolerana kuyenera kukhala kofanana kulolerana ndipo sikuyenera kukhazikitsidwa ku mawonekedwe a asymmetric kulolerana mmwamba ndi pansi.Mwachitsanzo, D30 + 3/-5NM si yolondola. Popanga, mphamvu ya torque yamphamvu ya chida chomangirira iyenera kukhala mwadzina, ndipo sayenera kupatutsidwa pamtengo wadzina mwadala;

2. Torque yosasunthika

SA-BNM;Nthawi yokhazikika iyenera kulembedwa ngati mitundu yosiyanasiyana monga: S25-35NM;Palibe danga pakati pa S ndi 25-30NM;Kumene S akuyimira Static;A amayimira malire apansi a torque yokhazikika, B amayimira malire apamwamba a torque yosasunthika;NM ndi gawo la torque: Newton.Mamita;

Ma torque amphamvu komanso mawonekedwe olembera a torque

3. Misomali yamphamvu ya misomali yokhazikika Misomali yokhazikika nthawi zambiri imakhala pansi pa muyezo wa FDSNS (Fully DrivenSeated Not Stripped) .Mwachitsanzo: D1.5 +/-0.5NM S1NM MIN FDSNSWapo D imayimira Mphamvu (yamphamvu);Kutsatiridwa ndi danga; 1.5 +/- 0.5NM ikuwonetsa kuchuluka kwa torque yamphamvu, 1.5NM ndiyongofotokozera za torque yeniyeni popanga, ndipo siyimawonetsedwa ngati mtengo wadzina.Mphamvu yeniyeni yomwe imagwiritsidwa ntchito imasinthidwa ndi kupanga molingana ndi momwe zilili zenizeni za torque yamfuti, koma ziyenera kutsimikiziridwa kuti muyezo wa FDSNS (Fully Driven SeatedNot Stripped, ndiko kuti, dzino silikugwedezeka). Pomaliza, onani FDSNS (Yoyendetsedwa Mokwanira Osadulidwa).

Zinthu zomwe zimakhudza mphamvu ya torque

Mukayika torque yamphamvu, musaganizirenso zomangira, komanso zomangira ndi zida zomangira.Makokedwe osunthika ndi ochepa kwambiri, omwe ndi osavuta kuyambitsa kumasuka komanso kusweka kwa kutopa, komanso sikuthandiza kupanga zomangira;The dynamic torque ndi yayikulu kwambiri, yomwe ndi yosavuta kupangitsa zomangira kutulutsa, ngakhale kuthyoka, kutsetsereka mano, ndikuphwanyidwa ndi zomangira.Kulimba kwazinthu, kuuma kwapamwamba, kugundana kwapamtunda ndi kapangidwe ka cholumikizira kudzakhudza mphamvu yamphamvu yofunikira. .Panthawi imodzimodziyo, m'pofunikanso kuganizira za mphamvu ya chomangira kuti zitsimikizire kuti sizidzaphwanyidwa, ndiyeno mutenge torque yaikulu yomwe chomangiracho chingathe kupirira. chomangira.Ma torque ocheperako akuyenera kuwonetsetsa kuti siwomasuka pakagwiritsidwe ntchito kwa kasitomala, ndipo torque yayikulu iyenera kuwonetsetsa kuti cholumikizira ndi chomangira sichilephera (monga kulolera, kuswa, kutsetsereka, kuphwanya, kusinthika, ndi zina). Kuti mupereke kusewera kwathunthu pamachitidwe a zomangira, ma axial preload of fasteners nthawi zambiri amayenera kukhala 50 mpaka 75% ya zomangira zotsimikizika.
