Lumikizani pisitoni ndi crankshaft, ndi kufalitsa mphamvu pa piston kupita ku crankshaft, kusintha njira yobwezeretsanso pisitoni mu njira yosinthitsira ya crankshaft.
Gulu lolumikiza la rod limakhala lolumikiza thupi la rod, lolumikiza rod yayikulu kumapeto, cholumikiza rod yaying'ono kumapeto kwake, cholumikiza rod kumapeto ndikulumikiza ndodo (kapena zomangira). Gulu lolumikizira ndodo limayang'aniridwa ndi pini ya piston yochokera ku piston pini, kusenda kwake ndikubwezera gulu la piston. Kukula ndi malangizo a mphamvu izi kumasintha nthawi ndi nthawi. Chifukwa chake, ndodo yolumikizira inkachitika kuti igwirizane ndi katundu monga kuponderezana ndi kusokonezeka. Ndodo yolumikizira iyenera kukhala ndi mphamvu yokwanira kutopa ndi mphamvu. Matenda osakwanira nthawi zambiri amapangitsa kuti thupi lolumikiza la rod kapena rod bod kuti iswe, chifukwa cha ngozi yayikulu yowonongeka pamakina onse. Ngati kuuma sikokwanira, kumapangitsa kuti musinthe kwa thupi ndi kutuluka kwamphamvu kwa ndodo yolumikizira, zomwe zimapangitsa kuti pakhale pisitoni, kuvala pini ya Clinder.
Kapangidwe ndi kapangidwe kake
Thupi lolumikizira limakhala ndi magawo atatu, gawo lolumikizidwa ndi pini piston limatchedwa kumapeto kwenikweni kwa ndodo yolumikiza; Gawo lolumikizidwa ndi crankshaft limatchedwa kumapeto kwa ndodo yolumikizira, ndipo gawo lolumikizani kumapeto kwenikweni komanso kumapeto kwakukulu kumatchedwa thupi lolumikiza.
Mapeto ang'onoang'ono a ndodo yolumikizayo ndi malo owonda kwambiri. Kuti muchepetse kuvala pakati pa ndodo yolumikizira ndi piston pini, yotsekemera yamkuntho yochepa kwambiri imakanikizidwa mu dzenje laling'ono. Kubowola kapena mphero zotayira mumutu ndi bush kuti mulole mafuta owuma kuti alowetse mawonekedwe a zopaka zopaka mafuta opangira mafuta ndi piston.
Shaft yolumikiza ndodo ndi ndodo yayitali, ndipo imachitidwanso ndi magulu akulu nthawi yantchito. Pofuna kupewa kuti zisagwedezeke ndi kuwonongeka, thupi la ndodo liyenera kukhala ndi thambo lokhazikika. Pachifukwa ichi, ambiri mwa ndodo zolumikizira zamagalimoto amagwiritsa ntchito zigawo za I - zomwe zimachepetsa unyinjiwu ndikukhazikika, komanso zigawo zopangidwa ndi H. Majini ena amagwiritsa ntchito njira yaying'ono ya ndodo yolumikizira kuti muzizire pisiton, ndipo dzenje liyenera kuwuma mu chimphepo cha rod. Pofuna kupewa kupsinjika, kulumikizana pakati pa rod thupi ndi kumapeto kwenikweni komanso kutha kwapamwamba kumatengera kusintha kosalala kwa Arc wamkulu.
Kuti muchepetse kugwedeza injini, kusiyana kwakukulu kwa cylinder iliyonse yolumikizira ndodo iyenera kukhala yocheperako. Mukasonkhanitsa injini mufakitale, nthawi zambiri imagawika malinga ndi unyinji wa malekezero akuluakulu ndi yaying'ono ya ndodo yolumikizira mu magalamu. Gulu lolumikizira ndodo.
Pa injini ya V
Mtundu waukulu wowonongeka
Zowonongeka zazikulu mitundu yolumikizira ndi zotupa za kutopa komanso kuphatikizika kwakukulu. Nthawi zambiri kutopa kumapezeka m'malo atatu opanikizika pa ndodo yolumikizira. Zoyenda zolumikizira za ndodo yolumikizira zimafunikira ndodo yolumikizira kuti ikhale yolimba komanso yolimba; Zimafunanso kukhwima kokwanira komanso kulimba. Mwachikhalidwe cholumikiza cha Rod, zomwe zida zimagwiritsidwa ntchito zozikidwa ndi chitsulo chokhazikika monga chitsulo 45, 40CR kapena 40mm, yomwe imakhala yolimba kwambiri. Chifukwa chake, zida zatsopano zolumikizira zida zopangidwa ndi makampani a Germany monga C70S6 Microbon Microaly osasunthika, a Spaitasco adapanga chitsulo, ndi s53cv-fs onse opangidwa ndi miyeso ya ku Germany). Ngakhale kuti chitsulo chimakhala ndi mphamvu yayikulu, limakonda kwambiri kupsinjika. Chifukwa chake, zomwe zimafunikira mu ndodo yolumikiza, fillet yowonjezera, ndi zina zambiri, komanso chidwi ziyenera kulipirira malo osokoneza bongo kuti zitheke.
