2-Chibwano vs 3-Njaw Pullers: Kusiyana kwake ndi chiyani?
You're trying to pull a gear, koma wokoka amangoterereka. Kugwira kosagwirizana ndi njira yopangira shaft yowonongeka kapena chida chowuluka pansi pa kupanikizika, kutembenuza ntchito yosavuta kukhala ngozi yachitetezo.
Kusiyana kwakukulu ndi bata[^1] ndi kugawa mphamvu. Chokoka nsagwada zitatu chimagwira motetezeka kwambiri ndikugwiritsa ntchito mphamvu mofanana, kuzipangitsa kukhala zotetezeka kuntchito zambiri. Chokoka 2-nsagwada ndi chida chapadera chomwe chimagwiritsidwa ntchito pokhapokha ngati danga lathina kwambiri nsagwada zitatu.
[chosungira chithunzi]
Kumayambiriro kwa ntchito yanga ya uinjiniya, Ndinali pamalo opangira zakudya komwe akatswiri okonza zakudya amakoka chikwangwani kuchokera pagalimoto yonyamula katundu. Anagwiritsa ntchito a 2-chokoka nsagwada[^2] chifukwa anali woyamba kugwira. Ndi kutembenuka kulikonse kwa wrench, Ndidawona mikono yokoka ikugwedezeka ndikuyesa kupotoza. Anali kulimbana kuti akhazikike pakati pomwe akugwiritsanso ntchito mphamvu. Zinali zowoneka bwino za momwe mphamvu zopanda malire zimapangira ngozi. Kwa manejala ngati Michael, amene amafunikira gulu lake kuti ligwire ntchito moyenera komanso moyenera, Kuwona kulimbanako kumatsindika mfundo yosavuta: kukhala ndi nambala yoyenera ya nsagwada sizinthu zazing'ono. Ndikofunikira pachitetezo, kukoka kopambana.
Kodi Kusiyana Kwakukulu Kwamapangidwe Ndi Chiyani?
Mukuwona zokoka ziwiri mubokosi la zida, imodzi ya nsagwada ziwiri ndi ina itatu. Amawoneka ofanana, koma mukudziwa kusiyana kwa mapangidwe ndikofunikira. Zomwe zimawapangitsa kukhala osiyana kwambiri?
Kusiyana kuli mu geometry. A 3-chokoka nsagwada[^3] amagawa clamping ndi kukoka mphamvu[^4]s pa 120-degree intervals, kupanga moyenera, kudziphatika. A 2-chokoka nsagwada[^2] imagwira ntchito mwamphamvu pa 180 madigiri, zomwe mwachibadwa sizikhazikika.
Geometry ya Grip
Kuchokera pamalingaliro aukadaulo wamakina, kusiyana pakati pa 2-nsagwada ndi 3-chokoka nsagwada[^3] zonse zimatengera momwe mphamvu zimayendera. Ganizilani a 3-chokoka nsagwada[^3] ngati chopondapo chamiyendo itatu; it's naturally stable. Mfundo zitatu zolumikizana zimakonzedwa mu makona atatu, 120 madigiri mosiyana. Mukamagwiritsa ntchito mphamvu yokoka, nsagwada kukanikiza mkati pa chigawocho ndi ofanana kuthamanga, kungoyika chida pamtengowo. Izi zimapanga chitetezo, chogwira chokhazikika chomwe sichingathe kutsetsereka. A 2-chokoka nsagwada[^2] zili ngati kuyesa kuima pamiyendo iwiri. Nsagwada ziwirizo zimagwiritsa ntchito mphamvu pazigawo zosiyana, 180 madigiri mosiyana. Kukonzekera uku kulibe chibadidwe wodzikonda[^5] kuthekera. Ngati mphamvu sizikugwirizana bwino, wokoka amatha kupotoza kapena "kuyenda" kuchokera pagawo, zomwe zingawononge gawolo kapena kupangitsa chida kulephera.

Kukhazikika Kumafananiza Bwanji Pakati pa Awiriwo?
Mukudziwa a 3-chokoka nsagwada[^3] ndi wokhazikika, koma chifukwa chiyani zili zofunika kwambiri? Ntchito ndi kungokoka chotengera. Izi zowonjezera bwanji bata[^1] kumasulira kukhala mwayi weniweni wapadziko lapansi?
Kukhazikika kwapamwamba kwa a 3-chokoka nsagwada[^3] mwachindunji amamasulira ku chitetezo[^6] ndi kuteteza kuwonongeka. Zimatsimikizira za kukoka mphamvu[^4] imayikidwa mofanana, kumateteza tsinde ndi kunyamula kupsinjika kokhazikika komanso kupewa kutsetsereka koopsa.
Kukhazikika Kumafanana ndi Chitetezo ndi Kulondola
The bata[^1] mwa a 3-chokoka nsagwada[^3] ndi mbali yake yofunika kwambiri. Pamene chokoka chili chokhazikika, zikutanthauza kuti mphamvu ikugwiritsidwa ntchito ndendende motsatira nsonga ya shaft. Kugawa ngakhale kumeneku ndikofunikira pazifukwa ziwiri. Choyamba, chitetezo[^6]. Wosakhazikika 2-chokoka nsagwada[^2] imatha kuchoka pagawoli mwamphamvu kwambiri, kukhala projectile yoopsa. Mphamvu zosungidwa zimatulutsidwa nthawi yomweyo, ndipo zimenezi zingachititse munthu kuvulala kwambiri. Chachiwiri, chitetezo cha zinthu. Pamene chokoka chimagwiritsa ntchito mphamvu mosagwirizana, imayika katundu wopindika kapena wokhotakhota pamtengowo ndipo chigawocho chikuchotsedwa. Izi zitha kuyika shaft yolondola kwambiri, sinthani zida zolimba, kapena kusokoneza mpikisano wothamanga. Mtengo wokonzanso mtengo wowonongekawo nthawi zambiri umaposa mtengo wa chokokacho. Manijala ngati Michael amadziwa kuti kuletsa ngakhale chochitika chimodzi chotere kumapangitsa kuyika ndalama pachida chokhazikika kukhala chisankho chabwino pazachuma.
Ndi Njira Zabwino Zotani Zogwiritsira Ntchito Pamtundu Uliwonse?
Katswiri wanu ayenera kukoka gawo. Kodi iwo basi kufika kwa 3-chokoka nsagwada[^3] nthawi iliyonse, kapena pali zochitika zomwe a 2-chokoka nsagwada[^2] ndiye kusankha kwabwinoko?
Nthawi zonse kusakhazikika ku a 3-chokoka nsagwada[^3] za zake chitetezo[^6] ndi bata[^1]. Gwiritsani ntchito a 2-chokoka nsagwada[^2] pamene zopinga zakuthupi zimapangitsa kuti zikhale zosatheka kugwirizana ndi nsagwada yachitatu kuzungulira chigawocho.
Kusankha Kutengera Kufikira, Osati Kukonda
Njira yopangira chisankho iyenera kukhala yosavuta: nthawi zonse yesetsani kugwiritsa ntchito a 3-chokoka nsagwada[^3] choyamba. Zake chitetezo[^6] ndi bata[^1] chipange kukhala chida chapamwamba kwambiri. Ndikunena magulu okonza[^7] kuganiza za 3-chokoka nsagwada[^3] monga chida chawo muyezo ndi 2-chokoka nsagwada[^2] monga wothetsera mavuto awo apadera. The kokha nthawi a 2-chokoka nsagwada[^2] kusankha kolondola ndi pamene palibe chilolezo chokwanira kuzungulira chigawocho kuti chigwirizane ndi nsagwada zitatu. Izi zikhoza kuchitika pamene pulley imayikidwa pafupi kwambiri ndi nyumba ya makina, kapena pamene mbali zina za msonkhano watsekereza mwayi. M'malo ovuta awa, a 2-chokoka nsagwada[^2]'s narrow profile allows you to get a grip where a 3-jaw simply won't fit. Komabe, mukamagwiritsa ntchito imodzi, wogwiritsa ntchitoyo ayenera kukhala wosamala kwambiri, kuonetsetsa kuti yakhazikika bwino ndikugwiritsa ntchito mphamvu pang'onopang'ono kuti isayende.
| Zochitika | Kusankha Kwabwino Kwambiri | Kulungamitsidwa |
|---|---|---|
| Zowonekera pamtengo wautali | 3-Chiwombankhanga | Kufikira kokwanira. Kukhazikika ndikofunikira pachitetezo, ngakhale kukoka. |
| Gear yokhala ndi mwayi wonse wa 360° | 3-Chiwombankhanga | Mphamvu yoyenera imalepheretsa kuwonongeka kwa zida ndikuwonetsetsa chitetezo[^6]. |
| Pulley adakwera pafupi ndi nyumba | 2-Chiwombankhanga | Njira yokhayo yomwe ingagwirizane ndi thupi mu malo olimba. |
| Galimoto yaying'ono mu msonkhano | 3-Chiwombankhanga | Ngakhale ntchito zazing'ono, ndi bata[^1] ndi wamtengo wapatali chitetezo[^6] mawonekedwe. |
| Kuchotsa chiwongolero | 2-Chiwombankhanga | Nthawi zambiri amapangidwa ndi mabowo awiri opangidwa ndi chida china cha 2-nsagwada. |
