Unyolo wodzigudubuza ndi mtundu wa unyolo womwe umagwiritsidwa ntchito popereka mphamvu zamakina.Ndi mtundu wa chain drive ndipo amagwiritsidwa ntchito kwambiri m'makina apanyumba, mafakitale ndi zaulimi, kuphatikiza ma conveyors, mapulani, makina osindikizira, magalimoto, njinga zamoto, ndi njinga.Zimagwirizanitsidwa pamodzi ndi ma roller afupiafupi a cylindrical ndipo amayendetsedwa ndi gear yotchedwa sprocket, yomwe ndi chipangizo chosavuta, chodalirika komanso chogwira ntchito chotumizira mphamvu.
1.Chiyambi cha Roller Chain:
Unyolo wodzigudubuza nthawi zambiri umatanthawuza maunyolo odzigudubuza olondola pamapatsira afupiafupi, omwe amagwiritsidwa ntchito kwambiri komanso otuluka kwambiri.Unyolo wodzigudubuza umagawidwa kukhala mzere umodzi ndi mizere yambiri, yoyenera kufalitsa mphamvu yaying'ono.Gawo lofunikira la unyolo wodzigudubuza ndi unyolo wolumikizira p, womwe ndi wofanana ndi nambala ya unyolo wa unyolo wochulukitsidwa ndi 25.4/16 (mm).Pali mitundu iwiri ya suffixes mu nambala ya tcheni, A ndi B, kusonyeza mindandanda iwiri, ndipo mindandanda iwiriyo imagwirizana.
2.Roller chain kapangidwe:
Unyolo wodzigudubuza umapangidwa ndi mbale yamkati yachitsulo 1, mbale yakunja ya 2, pin shaft 3, sleeve 4 ndi roller 5. Chipinda chamkati chamkati ndi manja, mbale yakunja ya unyolo ndi pini zonse ndizosokoneza. ;zodzigudubuza ndi manja, ndi manja ndi pini zonse ndi chilolezo.Pogwira ntchito, maulalo amkati ndi akunja a unyolo amatha kupotoza wachibale wina ndi mzake, manja amatha kuzungulira momasuka kuzungulira mphini ya pini, ndipo chogudubuza chimayikidwa pamanja kuti chichepetse kuvala pakati pa unyolo ndi sprocket.Pofuna kuchepetsa kulemera ndi kupanga mphamvu ya gawo lililonse kukhala lofanana, mbale zamkati ndi zakunja nthawi zambiri zimapangidwira "8" mawonekedwe.[2] Chigawo chilichonse cha unyolo chimapangidwa ndi chitsulo cha carbon kapena alloy steel.Kawirikawiri mwa kutentha mankhwala kukwaniritsa mphamvu inayake ndi kuuma.
3.Maonekedwe a Roller Chain:
Mtunda wapakati-ku-pakati pakati pa mapini awiri oyandikana nawo pa unyolo amatchedwa phula la unyolo, lotanthauzidwa ndi p, lomwe ndilo gawo lofunika kwambiri la unyolo.Pamene phula likuwonjezeka, kukula kwa gawo lililonse la unyolo kumawonjezeka moyenerera, ndipo mphamvu yomwe imatha kupatsirana imakulanso moyenerera.[2] Unyolo pitch p ndi wofanana ndi nambala ya unyolo wa unyolo wochulukitsidwa ndi 25.4/16 (mm).Mwachitsanzo, unyolo nambala 12, wodzigudubuza unyolo phula p=12×25.4/16=19.05mm.
4.Kapangidwe ka unyolo wodzigudubuza:
Maunyolo odzigudubuza amapezeka mumizere imodzi komanso mizere yambiri.Pamene kuli kofunikira kunyamula katundu wokulirapo ndikufalitsa mphamvu yokulirapo, mizere ingapo ya maunyolo ingagwiritsidwe ntchito, monga momwe tawonetsera pa Chithunzi 2. Mizere ya mizere yambiri imakhala yofanana ndi maunyolo angapo wamba a mzere umodzi wogwirizana wina ndi mzake ndi zikhomo zazitali.Zisakhale zambiri, zomwe zimagwiritsidwa ntchito kawirikawiri ndi maunyolo amizere iwiri ndi mizere itatu.
5.Fomu yolumikizana ndi Roller:
Kutalika kwa unyolo kumayimiridwa ndi chiwerengero cha maunyolo.Nthawi zambiri, ulalo wa unyolo wofananira umagwiritsidwa ntchito.Mwanjira iyi, zikhomo zogawanika kapena zidutswa za masika zitha kugwiritsidwa ntchito pamalumikizidwe a unyolo.Pamene mbale yopindika ya unyolo ili pansi pa zovuta, mphindi yopindika yowonjezera idzapangidwa, ndipo nthawi zambiri iyenera kupewedwa momwe zingathere.
6.Roller chain standard:
GB/T1243-1997 imanena kuti maunyolo odzigudubuza amagawidwa m'magulu A ndi B, pakati pawo mndandanda wa A umagwiritsidwa ntchito pa liwiro lapamwamba, katundu wolemetsa komanso kutumiza kofunikira, komwe kumagwiritsidwa ntchito kwambiri.Nambala ya unyolo wochulukitsidwa ndi 25.4 / 16mm ndiye mtengo wa phula.B mndandanda umagwiritsidwa ntchito kufala.Chizindikiro cha unyolo wodzigudubuza ndi: unyolo nambala wani mzere woyamba unyolo unyolo nambala wani nambala yokhazikika.Mwachitsanzo: 10A-1-86-GB/T1243-1997 amatanthauza: A mndandanda wodzigudubuza unyolo, phula ndi 15.875mm, mzere umodzi, chiwerengero cha maulalo ndi 86, kupanga muyezo GB/T1243-1997
7.Kugwiritsa ntchito unyolo wodzigudubuza:
Chain drive imagwiritsidwa ntchito kwambiri pamakina osiyanasiyana m'mafakitale osiyanasiyana monga ulimi, migodi, zitsulo, mafakitale a petrochemical ndi zonyamula katundu.Mphamvu yomwe kufala kwa unyolo kumatha kufikira 3600kW, ndipo nthawi zambiri imagwiritsidwa ntchito ngati mphamvu pansi pa 100kW;liwiro la unyolo limatha kufika 30 ~ 40m / s, ndipo liwiro lomwe limagwiritsidwa ntchito nthawi zambiri lili pansipa 15m / s;~ 2.5 ndi yabwino.
8.Makhalidwe a roller chain drive:
ubwino:
Poyerekeza ndi lamba pagalimoto, ilibe zotanuka kutsetsereka, akhoza kukhala olondola pafupifupi kufala chiŵerengero, ndipo ali mkulu kufala Mwachangu;unyolo sufuna mphamvu yayikulu yolimbana, kotero katundu pamtengo ndi kubereka ndi wochepa;sichidzazembera, kufalikira ndi kodalirika, ndi kuchulukira Kwamphamvu Kwambiri, kumatha kugwira ntchito bwino pansi pa liwiro lotsika komanso katundu wolemera.
kusowa:
Kuthamanga kwa nthawi yomweyo unyolo ndi kusintha kwa nthawi yomweyo kufala kwa chiŵerengero, kusasunthika kwa kufalitsa kumakhala kosauka, ndipo pali zododometsa ndi phokoso panthawi ya ntchito.Sikoyenera pazochitika zothamanga kwambiri, ndipo sikoyenera kusintha pafupipafupi pozungulira.
9.njira yopanga:
Malinga ndi kafukufuku, kugwiritsa ntchito maunyolo ku China kuli ndi mbiri yazaka zopitilira 3,000.Kale ku China, magalimoto otayira ndi mawilo amadzi omwe amagwiritsidwa ntchito kunyamula madzi kuchokera pansi kupita kumtunda ndi ofanana ndi maunyolo amakono onyamula.Mu "Xinyixiangfayao" yolembedwa ndi Su Song ku Northern Song Dynasty ku China, zalembedwa kuti zomwe zimayendetsa kuzungulira kwa zida zankhondo zili ngati chida chotumizira maunyolo chopangidwa ndi chitsulo chamakono.Zitha kuwoneka kuti China ndi amodzi mwa mayiko oyamba kugwiritsa ntchito maunyolo.Komabe, mawonekedwe oyambira a unyolo wamakono adayamba kupangidwa ndikupangidwa ndi Leonardo da Vinci (1452-1519), wasayansi wamkulu komanso wojambula ku Europe Renaissance.Kuyambira pamenepo, mu 1832, Galle ku France adapanga tcheni cha pini, ndipo mu 1864, tcheni chopanda manja cha Slaite ku Britain.Koma anali a Swiss Hans Reynolds amene anafikadi pa mlingo wa mapangidwe amakono a unyolo.Mu 1880, adakwaniritsa zophophonya zamaketani am'mbuyomu, adapanga unyolowo kukhala gulu lodziwika bwino la unyolo wodzigudubuza, ndipo adapeza unyolo wodzigudubuza ku UK.chain invention patent.
