Ngati mukusintha ma bolts panjinga yanu, wrench ya torque ndiyofunika kwambiri kuti mutsimikizire kuti simukulimbitsa kwambiri kapena kukulitsa.Pali chifukwa chomwe mukuwona zida zolimbikitsira m'mabuku ambiri okonza ndi zolemba.
Pamene zida za chimango zikusintha, kulolerana kumakhala kolimba, ndipo izi ndizowona makamaka pamafelemu a carbon fiber ndi zigawo zake.Ngati mabawuti achulukana kwambiri, kaboniyo imasweka ndipo pamapeto pake imalephera.
Komanso, mabawuti osamangika amatha kupangitsa kuti zinthu ziziyenda kapena kumasuka pokwera.
Mulimonsemo, ndikofunikira kuwonetsetsa kuti ma bolts panjinga yanu ali olimba, ndipo wrench ya torque idzakuthandizani ndi izi.
Apa tikuwonetsani zomwe muyenera kuchita ndi zomwe musachite za ma wrenches a torque, mitundu yosiyanasiyana, momwe mungagwiritsire ntchito chidacho moyenera komanso ma wrenche abwino kwambiri omwe tayesa mpaka pano.
Wrench ya torque ndi chida chothandiza kwambiri chomwe chimayesa momwe mumamangirira bolt, chomwe chimatchedwa torque.
Mukayang'ana njinga yanu, nthawi zambiri mumawona nambala yaing'ono pafupi ndi bawuti, yomwe nthawi zambiri imalembedwa "Nm" (mamita a newton) kapena nthawi zina "mu-mapaundi" (mu-lbs).Ichi ndi gawo la torque lofunikira pa bolt.
Onetsetsani kuti akuti "Maximum" torque.Ngati ndi "max" ndiye inde, ndipo muchepetse torque yake ndi 10%.Nthawi zina, monga momwe zimakhalira ndi ma bolts a Shimano, mumatha kukhala ndi mtundu womwe muyenera kuyang'ana pakati pawo.
Ngakhale pali okayikira ambiri omwe amatsutsa zida zotere omwe amasangalala kugwira ntchito kuti "amve", zoona zake n'zakuti ngati mukulimbana ndi zigawo zosakhwima, kugwiritsa ntchito wrench ya torque kumachepetsa kwambiri mwayi woti chinachake chikuyenda bwino.zikafika pa chitsimikizo chanu (ndi mano).
Ichi ndichifukwa chake ma wrenches a njinga amakhalapo, ngakhale mutha kugwiritsa ntchito mawotchi opangira ma bawuti omwe amafunikira ma torque apamwamba, monga ma freewheel, mphete zosungira ma disc, ndi ma bolts.The makokedwe pazipita muyenera kugwiritsa ntchito njinga ndi 60 Nm.
Pamapeto pake, wrench yabwino kwambiri pazosowa zanu zimadalira nthawi yomwe mukufuna kuzigwiritsa ntchito komanso mbali ziti zanjinga yanu yomwe mukufuna kuzigwiritsa ntchito.Ndikoyenera nthawi zonse kuyika ndalama pazosankha zapamwamba kuti zikhale zolondola komanso zosavuta kugwiritsa ntchito.
Nthawi zambiri, pali mitundu inayi ya ma torque: yokhazikika, yosinthika, yosinthika pang'ono ndi ma wrenches amtengo.
Ngati mungogwiritsa ntchito wrench yanu ya torque pazinthu monga tsinde ndi ma bolts, mutha kusunga ndalama ndikugula zopangira zokhazikitsidwa kale kutengera torque yomwe mukufuna panjinga yanu.
Mawotchi oyikiratu oyikiratu ndi abwino ngati mumagwiritsa ntchito njinga zosiyanasiyana nthawi zonse kuti musunge nthawi yokhazikitsa ma wrenches osinthika.
Nthawi zambiri mumatha kugula ma wrenches a torque preset pa 4, 5, kapena 6 Nm, ndipo mapangidwe ena amaperekanso kusintha kosinthika mumtundu uwu.
Popeza zosankha zomwe zidakonzedweratu nthawi zambiri zimakhala zazikulu kwambiri pamapangidwe, ndipo ngati mukugwiritsa ntchito makina omangira chishalo kapena ma wedge, omwe nthawi zambiri amafunikira mutu wochepa, muyenera kuwonetsetsa kuti muli ndi malo okwanira kuyika chidacho.
Njirayi imakhalanso yopepuka, kotero ngati mukupita kutchuthi, ichi ndi chisankho chabwino.
Tsoka ilo, izi zikutanthauza kuti ndi mtundu wodula kwambiri, wokhala ndi mitengo yoyambira pa £30 mpaka £200.
Kulondola kwakukulu ndiko kusiyana kwakukulu ndipo pamapeto pake wrench ya torque ndiyothandiza ngati ili yolondola.
Pamene mumagwiritsa ntchito zambiri, kusiyana kwina kumaphatikizapo ma bits apamwamba kwambiri ndi zizindikiro zoyimba zomwe zimakhala zosavuta kuwerenga ndi kusintha, zomwe zimapangitsa kuti musalakwitse.
Zosawoneka bwino koma zochulukirachulukira, wrench ya torque ndi wrench yonyamula ngati kubowola kokhala ndi torque.
Nthawi zambiri amakhala ndi chogwirira ndi kubowola ndi ndodo ya torque.Mipiringidzo ya torque nthawi zambiri imakhala ndi manambala omwe amawonetsa torque ndi muvi pansipa.Mukatha kusonkhanitsa chidacho, mutha kumangitsa ma bolts, motsatira miviyo mosamala, mpaka mutafika pa torque yomwe mukufuna.
Opanga ena, monga Silca, amapereka ma modular T- and L-handle bit system omwe ali oyenera malo ovuta kufikako.
Itha kukhala njira yabwino kwambiri yopangira maholide apanjinga kapena ngati katundu wamanja panjinga popeza ilinso ndi zida zambiri, njira yabwinoko chabe.
Njira yomaliza ndi wrench ya torque yokhala ndi mtengo.Izi zinali zofala kusanabwere kwa zosankha zosinthika zomwe zilipo.Mitundu ina, monga Canyon, imakhala ndi wrench yamtengo potumiza njinga.
Ma wrenches amtengo ndi otsika mtengo, osathyoka, ndipo ndi osavuta kuwongolera - onetsetsani kuti singano ili paziro musanagwiritse ntchito, ndipo ngati sichoncho, pindani singanoyo.
Kumbali ina, muyenera kuwerenga mtengo motsutsana ndi sikelo kuti mudziwe kuti muli ndi torque yoyenera.Izi zitha kukhala zovuta ngati gawo lomwe mukulimitsa silinasindikizidwe pamlingo, kapena ngati mukuyang'ana ma decimals.Mudzafunikanso dzanja lokhazikika.Mawotchi ambiri a njinga zamoto amakhala olunjika polowera msika ndipo nthawi zambiri amapangidwa ndi pulasitiki kapena zinthu zofewa.
