Tanthauzo la ulusi wa fastener
Ulusi ndi mawonekedwe okhala ndi mawonekedwe ozungulira ozungulira panja kapena mkati mwa cholimba.
Pali mitundu itatu ikuluikulu ya ulusi: ulusi, ulusi wodziwombera komanso ulusi wodzibowolera.
Mtundu wa makina:pa msonkhano, kubowola dzenje pamsonkhano kuti mugwire ulusi, ndipo ulusi wamkati wotsekedwa ndi wofanana ndi ulusi wakunja wa screw, kotero msonkhanowo umachitika ndi torque yaing'ono.
Kudzigunda pawekha:pa msonkhano, kubowola mabowo mu msonkhano poyamba, popanda kugogoda mano amkati, ndi ntchito makokedwe lalikulu msonkhano.
Ulusi wodzibowolera:itha kugwiritsidwa ntchito mwachindunji pagulu, ndipo wononga imatha kubowoleredwa ndikumangidwa kuti mupange ulusi mu sitepe imodzi.
Screw action of fastener
1. Kumanga ndi kulumikiza ntchito: imagwira ntchito pazinthu zambiri zowononga panthawiyi.
2. Transmission action (displacement action): mwachitsanzo, micrometer yogwiritsidwa ntchito ndi QC kuyang'ana miyeso.
3. Ntchito yosindikiza: monga kulumikiza ndi kusindikiza mapaipi.
Ulusi wokhuthala ndi ulusi wabwino
Ulusi wotchedwa coarse ukhoza kufotokozedwa ngati ulusi wokhazikika; Komabe, ulusi wabwino umagwirizana ndi ulusi wokhuthala. Pansi pa mainchesi omwewo mwadzina, chiwerengero cha mano pa inchi ndi chosiyana, ndiko kuti, phula la ulusi wokhuthala ndi lalikulu, pomwe la ulusi wabwino ndi laling'ono. Izi zikutanthauza kuti, chifukwa cha 1/2-13 ndi 1/2-20, choyambirira ndi mano okhwima ndipo chomaliza ndi mano abwino. Chifukwa chake, amawonetsedwa ngati 1/2-13UNC ndi 1/2-20UNF.
Ulusi wokhuthala
Tanthauzo: Mano otchedwa okantha kwenikweni amanena za ulusi wokhazikika. Pokhapokha ngati tanenedweratu, zomangira monga zomangira zitsulo zosapanga dzimbiri zomwe timagula nthawi zambiri ndi mano okalipa.
Makhalidwe a ulusi wobiriwira: umakhala ndi mphamvu zambiri, umasinthasintha bwino ndipo ukhoza kufananizidwa ndi miyezo. Nthawi zambiri, ulusi wolimba uyenera kukhala wabwino kwambiri;
Poyerekeza ndi ulusi wabwino: chifukwa cha phula lalikulu, ngodya yayikulu ya ulusi komanso kudzitsekera koyipa, ndikofunikira kukhazikitsa makina ochapira cheke ndi chida chodzitsekera m'malo ogwedezeka; Ali ndi ubwino disassembly yabwino ndi msonkhano, wathunthu zofananira magawo muyezo ndi interchangeability zosavuta;
Zindikirani: Sikoyenera kulemba phula la ulusi wobiriwira, monga M8, M12-6H, M16-7H, ndi zina zotero, ndipo amagwiritsidwa ntchito makamaka ngati ulusi wolumikiza.
Ulusi wabwino
Tanthauzo: Mano abwino amangosiyana kwambiri ndi mano okhwangwala, amene amanenedwa kuti awonjezere zofunika pakugwiritsa ntchito mwapadera zomwe ulusi wamano okanika sungathe kukwaniritsa. Ulusi wa mano abwino umakhalanso ndi phula, ndipo phula la mano abwino ndi laling'ono, choncho makhalidwe ake amathandiza kwambiri kudzitsekera komanso kutsutsa kumasula, ndipo chiwerengero cha mano chingachepetse kutayikira ndikukwaniritsa kusindikiza. Nthawi zina mwatsatanetsatane, zomangira zachitsulo zosapanga dzimbiri zimakhala zosavuta kuwongolera ndikuwongolera bwino.
Zoipa: Mtengo wokhazikika komanso mphamvu zake zimakhala zochepa poyerekeza ndi mano okhwima, ndipo ulusi ndi wosavuta kuwonongeka. Sitikulimbikitsidwa kusokoneza ndikusonkhanitsa nthawi zambiri. Zomangira zofanana monga mtedza zingakhale zolondola mofanana, ndipo kukula kwake ndi kolakwika pang'ono, zomwe zingawononge mosavuta zomangira ndi mtedza nthawi imodzi.
Ntchito: Ulusi Wabwino umagwiritsidwa ntchito kwambiri pazitsulo zazitsulo zamakina a hydraulic system, mawotchi opatsirana, mbali zoonda zokhala ndi mipanda yopanda mphamvu, ziwalo zamkati zomwe zimachepetsedwa ndi danga ndi ma shafts omwe ali ndi zofunikira zodzitsekera, ndi zina zotero. phula liyenera kulembedwa kuti liwonetse kusiyana ndi ulusi wokhuthala.
Kodi kusankha ulusi coarse ndi ulusi wabwino?
Onse ulusi wokhuthala ndi zomangira zabwino zimagwiritsidwa ntchito pomanga.
Zomangira za mano abwino nthawi zambiri zimagwiritsidwa ntchito kutseka mbali zokhala ndi mipanda yopyapyala komanso zokhala ndi zofunika kwambiri popewa kugwedezeka. Ulusi wabwino uli ndi ntchito yabwino yodzitsekera, motero imakhala ndi mphamvu yotsutsa kugwedezeka komanso kumasula. Komabe, chifukwa cha kuzama kwa ulusi, kutha kupirira kupsinjika kwambiri kumakhala koyipa kuposa ulusi wopyapyala.
Ngati palibe njira zotsutsana ndi kumasula zomwe zimatengedwa, mphamvu yotsutsa kumasula ya ulusi wabwino ndi yabwino kuposa ya ulusi wobiriwira, ndipo nthawi zambiri imagwiritsidwa ntchito pazigawo zopyapyala ndi zigawo zomwe zimakhala ndi zofunikira zotsutsana ndi kugwedezeka.
Pokonza, ulusi wabwino uli ndi ubwino wambiri. Kuipa kwa ulusi wabwino: Siwoyenera kuzinthu zokhala ndi mawonekedwe okhwima kwambiri komanso osalimba. Pamene mphamvu yomangirira ili yaikulu kwambiri, imakhala yosavuta kuzembera.
