Mu injini iliyonse yamakono pali mayunitsi okwera, omwe amayendetsedwa ndi lamba.Kuti mugwiritse ntchito bwino pagalimoto, gawo lowonjezera limalowetsedwamo - chowongolera lamba.Werengani zonse za gawoli, kapangidwe kake, mitundu ndi magwiridwe antchito, komanso kusankha koyenera ndikusintha m'nkhaniyi.
Kodi tensioner lamba woyendetsa ndi chiyani?
Drive lamba tensioner (zovuta wodzigudubuza kapena pagalimoto lamba tensioner) - gawo la dongosolo galimoto kwa wokwera mayunitsi injini kuyaka mkati;wodzigudubuza ndi kasupe kapena makina ena omwe amapereka mlingo wofunikira wa kugwedezeka kwa lamba woyendetsa.
Ubwino wa kuyendetsa kwa mayunitsi okwera - jenereta, pampu yamadzi, pampu yowongolera mphamvu (ngati ilipo), compressor ya air conditioner - makamaka zimadalira kugwira ntchito kwa gawo lamagetsi komanso kuthekera koyendetsa galimoto yonse.Chofunikira pakugwira ntchito kwanthawi zonse kwa mayunitsi okwera ndikumangika koyenera kwa lamba wogwiritsidwa ntchito pagalimoto - ndi kupsinjika kofooka, lambayo amaterera pamitsempha, zomwe zingayambitse kuwonongeka kwa magawo ndi kuchepa kwamphamvu. Kuchita bwino kwa mayunitsi;Kukangana kopitilira muyeso kumawonjezeranso kuchuluka kwa mavalidwe a magawo oyendetsa ndikuyambitsa katundu wosavomerezeka.M'ma motors amakono, kuchuluka kofunikira kwa lamba woyendetsa kumaperekedwa ndi gawo lothandizira - chodzigudubuza kapena cholumikizira.
The tensioner lamba woyendetsa ndi wofunikira pakugwira ntchito bwino kwa gawo lamagetsi, chifukwa chake gawo ili liyenera kusinthidwa pakagwa vuto lililonse.Koma musanagule chodzigudubuza chatsopano, muyenera kumvetsetsa mitundu yomwe ilipo, mapangidwe ake ndi mfundo zake zogwirira ntchito.
Mitundu ndi kapangidwe ka ma lamba oyendetsa galimoto
Lamba wamtundu uliwonse uli ndi magawo awiri: chipangizo cholumikizira chomwe chimapanga mphamvu yofunikira, ndi chodzigudubuza chomwe chimatumiza mphamvu iyi ku lamba.Palinso zipangizo zomwe zimagwiritsa ntchito tensioner-damper - sizimangokhalira kugwedezeka kwa lamba, komanso kuchepetsa kukula kwa lamba ndi ma pulleys a mayunitsi mumayendedwe osakhalitsa a ntchito yamagetsi.
The tensioner akhoza kukhala ndi odzigudubuza mmodzi kapena awiri, mbali zimenezi amapangidwa mu mawonekedwe a zitsulo kapena pulasitiki gudumu ndi yosalala ntchito pamwamba pomwe lamba amagudubuza.Wodzigudubuza amayikidwa pa chipangizo chomangika kapena pa bulaketi yapadera kudzera muzitsulo zozungulira (mpira kapena roller, nthawi zambiri mzere umodzi, koma pali zipangizo zokhala ndi mizere iwiri).Monga lamulo, malo ogwiritsira ntchito odzigudubuza ndi osalala, koma pali zosankha ndi makola kapena ma protrusions apadera omwe amalepheretsa lamba kuti asagwere pamene injini ikuyenda.
Zodzigudubuza zimayikidwa mwachindunji pazida zomangirira kapena pazigawo zapakatikati mwamabulaketi amitundu yosiyanasiyana.Zipangizo zolimbitsa thupi zitha kugawidwa m'magulu awiri malinga ndi njira yosinthira mphamvu ya lamba yoyendetsa:
● Ndi kusintha kwamanja kwa digiri ya zovuta;
● Ndi kusintha basi mlingo wa mavuto.
Gulu loyamba limaphatikizapo njira zosavuta kwambiri zopangira, zomwe zimagwiritsa ntchito zida za eccentric ndi slide tensioning.The eccentric tensioner imapangidwa mwa mawonekedwe a wodzigudubuza ndi axis offset, pamene azunguliridwa mozungulira pomwe wodzigudubuza amabweretsedwa pafupi kapena kutali ndi lamba, zomwe zimapereka kusintha kwa mphamvu yamphamvu.Slide tensioner imapangidwa ngati chodzigudubuza chomwe chimayikidwa pa slider yosunthika yomwe imatha kuyenda motsatira poyambira (bracket).Kusuntha kwa wodzigudubuza pamodzi ndi kalozera ndi kukonza kwake pamalo osankhidwa kumachitidwa ndi screw, chiwongolerocho chimayikidwa perpendicular kwa lamba, choncho, pamene wodzigudubuza akuyenda motsatira, mphamvu yowonongeka imasintha.
Zipangizo zomwe zili ndi kusintha kwamanja kwa lamba pa injini zamakono sizigwiritsidwa ntchito kawirikawiri, chifukwa zimakhala ndi zovuta kwambiri - kufunikira kosintha kusokoneza panthawi yoyamba ya gawo ili komanso pamene lamba amatambasula.Zovuta zotere sizingapereke mlingo wofunikira wa kugwedezeka kwa lamba pa moyo wonse wautumiki, ndipo kusintha kwamanja sikupulumutsa nthawi zonse - zonsezi zimayambitsa kuvala kwambiri kwa magawo a galimoto.
Chifukwa chake, ma motors amakono amagwiritsa ntchito zida zolimbitsa thupi zosintha zokha.Zovuta zotere zimagawidwa m'magulu atatu malinga ndi kapangidwe ndi mfundo ya ntchito:
● Zotengera akasupe ozunzika;
● Kutengera psinjika akasupe;
● Ndi ma dampers.
Zida zomwe zimagwiritsidwa ntchito kwambiri zimatengera akasupe a torsion - ndizophatikizana komanso zimagwira ntchito zawo moyenera.Maziko a chipangizocho ndi kasupe wopindika wam'mimba mwake waukulu woyikidwa mu kapu ya cylindrical.Kasupe wokhala ndi koyilo imodzi yowopsa imakhazikika mugalasi, ndipo koyilo yotsutsana imakhazikika pa bulaketi ndi chodzigudubuza, galasi ndi bulaketi zimatha kuzunguliridwa pamakona ena ochepera ndi maimidwe.Popanga chipangizocho, galasi ndi bulaketi zimazunguliridwa pamakona ena ndikukhazikika pamalo awa ndi chipangizo chachitetezo (cheke).Mukayika chowotcha pa injini, chekecho chimachotsedwa ndipo bulaketi imasokonekera pochita kasupe - chifukwa chake, wodzigudubuza amapumira pa lamba, ndikupereka gawo lofunikira la kusokoneza kwake.M'tsogolomu, kasupe adzapitirizabe kupanikizika, kupanga kusintha kosafunikira.
Zipangizo zochokera ku akasupe oponderezedwa zimagwiritsidwa ntchito mobwerezabwereza, chifukwa zimatenga malo ambiri komanso sizigwira ntchito bwino.Maziko a tensioning chipangizo ndi bulaketi ndi wodzigudubuza, amene ali ndi swivel kugwirizana ndi zopotoka cylindrical kasupe.Kumapeto kwachiwiri kwa kasupe kumayikidwa pa injini - izi zimatsimikizira kusokoneza koyenera kwa lamba.Monga momwe zinalili kale, mphamvu yowonongeka ya kasupe imayikidwa pa fakitale, kotero mutatha kuyika chipangizo pa injini, cheke kapena fusesi ya mapangidwe osiyana amachotsedwa.
Kukula kwa tensioners ndi psinjika kasupe chinali chipangizo chokhala ndi ma dampers.Wotchinjiriza ali ndi mapangidwe ofanana ndi omwe tafotokozazi, koma kasupe amasinthidwa ndi damper, yomwe imayikidwa pa bulaketi ndi roller ndi mota mothandizidwa ndi eyelets.Damper imakhala ndi compact hydraulic shock absorber ndi kasupe wophimbidwa, ndipo chowombera chodzidzimutsa chikhoza kupezeka mkati mwa kasupe ndikuchita ngati chithandizo cha koyilo yomaliza ya masika.Damper ya mapangidwe awa imapereka kusokoneza koyenera kwa lamba, ndikuwongolera kugwedezeka kwa lamba poyambitsa injini komanso m'njira zosakhalitsa.Kukhalapo kwa damper mobwerezabwereza kumatalikitsa moyo woyendetsa mayunitsi okwera ndikuwonetsetsa kuti ikugwira ntchito bwino.
Pomaliza, ziyenera kudziwidwa kuti kapangidwe kameneka kamakhala ndi ma tensioners okhala ndi ma roller amodzi ndi awiri.Pankhaniyi, zida zodzigudubuza ziwiri zimatha kukhala ndi chipangizo chimodzi cholumikizirana, kapena zida zolekanitsa za odzigudubuza.Palinso njira zina zogwira mtima, koma zagawidwa pang'ono, kotero sitidzaziganizira pano.
Nkhani za kusankha, kusintha ndi kusintha kwa tensioner lamba wagalimoto
Wodzigudubuza wa lamba woyendetsa, monga lamba wokha, ali ndi zida zochepa, zomwe ziyenera kusinthidwa.Mitundu yosiyanasiyana ya tensioners ili ndi gwero losiyana - zina mwazo (zosavuta kwambiri) ziyenera kusinthidwa nthawi zonse komanso pamodzi ndi kusintha kwa lamba, ndi zipangizo zochokera ku akasupe ndi dampers zimatha kutumikira pafupifupi panthawi yonse ya mphamvu yamagetsi.Nthawi ndi njira yosinthira zida zamagetsi zimawonetsedwa ndi wopanga chipangizo china chamagetsi - malingaliro awa ayenera kutsatiridwa mosamalitsa, apo ayi zotsatirapo zoyipa zagawo lamagetsi zimatha, kuphatikiza kugwedezeka kwake (chifukwa cha kutentha kwambiri chifukwa choyimitsa mpope. ).
Mitundu yokhayo ndi zitsanzo za tensioners zomwe zimalimbikitsidwa ndi wopanga magetsi ziyenera kutengedwa kuti zilowe m'malo, makamaka magalimoto omwe ali pansi pa chitsimikizo.Zida "zosakhala zachibadwidwe" sizingafanane ndi "zachibadwidwe", kotero kuyika kwawo kumabweretsa kusintha kwa mphamvu ya lamba ndi kuwonongeka kwa kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake.Choncho, m'malo woterewu uyenera kuchitidwa pokhapokha pazovuta kwambiri.
Pogula tensioning chipangizo, muyenera kugula zigawo zonse zofunika kwa izo (ngati iwo sanaphatikizidwe) - fasteners, bulaketi, akasupe, etc. Nthawi zina, inu simungakhoze kutenga tensioners lonse, koma zida kukonza - odzigudubuza okha ndi anaika. zimbalangondo, mabulaketi, dampers anasonkhana ndi akasupe, etc.
Kusintha kwa lamba woyendetsa galimoto kuyenera kuchitidwa motsatira malangizo a kukonza ndi kukonza galimoto.Ntchitoyi ikhoza kuchitidwa ndi lamba woikidwa komanso kuchotsedwa kwa lamba - zonse zimadalira mapangidwe a galimotoyo komanso malo a chipangizo chothandizira.Mosasamala kanthu za izi, kuyika kwa ma tensioners a kasupe nthawi zonse kumachitika mofanana: chipangizo ndi lamba zimayikidwa poyamba m'malo mwawo, ndiyeno chekecho chimachotsedwa - izi zimabweretsa kumasulidwa kwa kasupe ndi kugwedezeka kwa mpweya. lamba.Ngati pazifukwa zilizonse kukhazikitsa kwa tensioner kotereku kumachitika molakwika, ndiye kuti kuyikanso kumakhala kovuta.
Ngati tensioning chipangizo molondola osankhidwa ndi kuikidwa pa injini, galimoto ya mayunitsi adzagwira ntchito bwinobwino, kuonetsetsa ntchito chidaliro lonse mphamvu unit.
