Chifukwa chiyani ma fasteners amamasuka?Kusanthula kwazomwe zimayambitsa kuchepetsedwa kwa torque ya fastener

Pali zinthu zambiri zomwe zimakhudza kuchepetsedwa kwa torque, chifukwa njira zosiyanasiyana zochepetsera ma torque sizili zofanana, zonse zomwe zili pamwambapa, kuchokera pamachitidwe ndi kapangidwe kake kuti muganizire njira zomwe zimathandizira pakuchepetsa kwa torque mwachidule motere, zachidziwikire, kusintha. miyeso siyimangokhala pazotsatirazi.Njira Yopanga:1.Kuuma kwapamtunda: kung'onoting'ono kwapamwamba, kusalala pamwamba pa zinthuzo, komanso kuchepetsedwa kwa torque pambuyo pothina.2.Kuuma kwa zinthu: Kupititsa patsogolo kuuma kwa zinthu, kumapangitsa kuti zinthu zakuthupi zikhale zovuta kwambiri pakati pa wina ndi mzake, kuchepetsedwa kwa torque.3.Zida zokometsera: pulasitiki kapena mphira, ndi zina zotero ziyenera kugwiritsidwa ntchito pang'ono momwe zingathere.Ngati ndi kotheka, njira yolimba yolimba iyenera kupangidwa kuti iwonetsetse kuti mphamvu yothina itatha kuchepetsedwa ikukwaniritsa zofunikira za malonda.4, kusankha bawuti: bawuti yabwino ya mano poyerekeza ndi phula la bawuti la mano ndi laling'ono, screw Angle ndi yaying'ono, yomwe sikugwiritsidwa ntchito. zosavuta kumasula, kotero kugwiritsa ntchito bwino mano bolt torque attenuation adzakhala otsika kuposa mano coarse

Njira Yopangira: 1.Njira yothina: Sinthani njira yomangirira, kulimbitsa masitepe awiri kapena kulimbitsa masitepe angapo, ndikuyimitsa 50ms muzitsulo zomangirira kuti mutulutse kupanikizika kwa zotanuka ndikuchepetsa kuchepa.2.Liwiro lomangitsa: Chogwiriziracho chikanikizidwa, burr amachoka pansi pa mphamvu yayikulu yolumikizira, mphamvu yothina "yaifupi" imachepa, torque yotsalirayo imachepetsa kuthamanga kwa liwiro, kucheperako koyambira kwa burr, komwe kumatsalira kumachepa. makokedwe amachepetsa, motero, kuchepetsa kuthamanga kwamphamvu kumatha kuchepetsa kutsitsa kwa torque.3.Kumangitsa motsatizana: Sinthani kulimba kwa axis imodzi kukhala ma nkhwangwa angapo omangika nthawi imodzi, zomwe zingachepetse kutsika kwa torque: kapena kutenga ma axis amodzi pang'onopang'ono kumangirira kwa torque chandamale, komwe kungathenso kuchepetsa kutsika kwa torque.
