Crank inji: bari mu ga

Modern motor kunshi wani jam'i na tsarin tsakanin wanda akwai lubrication tsarin, man tsarin da ƙonewa tsarin. Dukan su canza a kan lokaci, sha canje-canje da kuma zama mafi m. Amma akwai wasu sassa da suka kasance canzawa a ko'ina cikin dukan lokaci ta zama. Alal misali, a crank inji. Gaskiyar ita ce, tun bayan da sabuwar dabara, shi ya zauna a cikin na asali siffan.

Its amfani ne quite broadly kuma ba a iyakance wa ciki konewa injuna. Ana amfani da irin wannan majalisai inda shi ake bukata translational motsi, da zaran shi ne iya samar da ba kawai wannan lokaci na wadannan ƙungiyoyi, amma kuma akai gudun, wanda aka iyakance ta da tsawon da crankshaft gwiwa.

Crank inji aka amfani farko a kan wani tururi shigarwa sa'an nan, bayan da ciki konewa engine na da sabuwar dabara, hijira a latest ci gaba. Akwai iri biyu saituna: daya watsa ikon daga crankshaft zuwa daki-daki, abin da ya sa a gaba motsi, da na biyu da samun da shi ikon daga fistan, wanda shi ne a kan wasu ƙarshen a haɗa sanda.

La'akari da manufar kowane bangare dabam. Babban part - a crankshaft. Yana iya aika da da karfi a kan sanda ko, conversely, to sami shi. An yi high-ƙarfi steels, mafi sau da yawa sanya na Cast baƙin ƙarfe. An located flywheel wanda ake amfani da su a ajiye samu makamashi. Mutane da yawa masu motoci kafa wata hur flywheel a kan engine, yin wani crank inji mafi agile. Ya kawai da sauri samun lokacinta.

Yanzu a kan su da sanda. Haka kuma an yi na m karfe maki, saboda da matsa lamba a kan shi na iya zama saran. Bugu da ƙari kuma, shi yana cikin siffar sanda na-tashar, saboda ta nakasawa yana da tsanani sakamakon cewa lalacewar da kuma Silinda.

A crank inji yana da babban karfin juyi fiye da Rotary injuna, tun da shi ya yi amfani da manufa na feedback liba, Ina nufin, da ƙarfi ne kunnen doki da tsawon da gwiwa. Saboda haka ƙarshe: da more gwiwa, da hakan da karfin juyi. Next abu - da fistan. A fistan iya fitar da crankshaft matsayin ciki konewa engine, ko a yi maka da shi daga karfi kamar a cikin compressors. An yakan sanya daga aluminum, saboda yana bukatar mai taushi karfe, don kauce wa tareda žata bango na Silinda a harka na lamba. A kewaye ne circumferential GROOVES a wadda fistan zobba aka saka, suka bauta wa a rufe da kuma kara da matsa lamba. A wannan yanayin, da gas yi mafi aiki.

A crank inji na engine aka lasafta su samu cikin talakawan da karfin juyi da kuma gudun, a matsayin biya diyya ga daya siga take kaiwa zuwa wani hasara a cikin sauran. The sama yadda aka bayyana Hanyar kara farko, amma a wannan yanayin da fistan zai yi tafiya a daina nesa, wanda rinjayar da "rufi" juyin.

Vaz motor taro ne ba daban-daban daga sama. Ka tuna cewa duk sassa na crank dole ne sosai lubricated kamar yadda rotates sosai da sauri. Daga farkon samar da tsakanin ma'abota sassa matsa lamba man fim da aka halitta da yawa rage sa.
