Crankshaft - ichi ndechimwe chikuru zvinhu injini. Zviri chikamu crank mashandiro. It ane yakagozha mudziyo. Chii mashandiro? Ngatitarisei.
Kweguyo kugadzwa
Crankshaft anotora simba kubva pisitoni uye vatendeuki kuva nomuviri simba. mashandiro ichi kunokanganisa rotational simba. Anoshanda nguva pasi kumusoro mutoro. Naizvozvo, kuti zvizere haana kubuda akashaya kupera, crankshafts wakaumbwa yepamusoro, mukuru-simba vakakanda alloys simbi. Zvadaro nhengo dzose vakaomesa yakakwirira Frequency ano. Kusiyanisa miseve vakavirikidza counterweight kana pasina counterweight. Kolneval injini iri zvakananga injini redzimba. Kana design, izvozvo kazhinji anoenderana muinjini. Pasinei vamwe kusiyana mazano vane zvakawanda zvakafanana. Crankshaft - kunzwisisa anoverengeka zvikamu. kazhinji pane yokutevedzera pamwe mitsipa mana, asi panewo tripodal - The magazini inonyanya inoshandiswa mutsigiri chacho. Mugore-humburumbira matanhatu injini akatasva miseve, apo zvitsigiso akadaro 7. Kuti crankshaft kunge aitaura, counterweights anoshandiswa. Kana sepombi duku dhayamita, apo chete kushandiswa counterweights. Nokuda kumativi izvi anopiwa maximally ishande simba chikwata.
ebetsero michini
Saka, achiziva zvinhu crankshaft uye chii nemauto kuita pairi panguva oparesheni, zvinokwanisika kunzwisisa nei inowanikwa pakati pamatama uye crankpins zvishoma vakagumisa. Kanoita rokusamhanyira kukundikana. Pakati crank matama yaiva hara. Hurongwa uyo basa injini, akamudana "dzinza." Rakagadzirirwa nechokwadi kuti yunifomu kuvesa kuti injini basa rakanga kupfuura nepakati, kuita nomubato usingashandi torsional uye vachikotama mauto. The crankshaft iri - zvikamu uchishanda panguva pamatunhu aimhanya. Vachishandisa kutenderera crank mugodhi uye pazvitsigiso kunosimbiswa nemashoko ari zvishoma nezvishoma mumatope mabheyaringi. Rega zvinhu zviri yakaiswa kuguma kana pakati yakakura mutsipa. The zvebasa inobereka iri kudzivirira axial misha uye misha mashandiro. Kana isu funga kuti zvakawanda zvinofanira kuramba uye zvakajeka kuti basa iri chete mashandiro, zviri nyore kutaura kuti muitiro mukugadzira ari crankshaft nokungwarira akadzikama. Asi dzimwe nguva zvinoita kuti zvikavengwa razbalansiruemye akadzama. In kutengeswa zvinhu zvakadaro hazvisi kuwanikwa.
Work crankshaft mukati
The kushanda nhungamiro bani rose. Kana pisitoni iri maximally kubviswa, pamatama uye crank kuti crankshaft zvakarongwa muna rwonzi. Panguva ino mune combustion mumakamuri vesa chinotsva uye magasi kuti kutamisira pisitoni kusvika crankshaft. Pamwe pisitoni uye unobva tsvimbo unotii, musoro izvo cranks ari crankshaft. Kana kuitika vokupedzisira, stub tsvimbo runoita upwardly uye pisitoni inofamba nayo.
lubrication hurongwa
An rinokosha iri kuridzwa ne mafuta. Crankshaft - munhu zvakadzama pamusoro kutenderera, izvo zvinoreva kuti Unozonzwa kukweshera. Of yose noukama mutsetse kusvikira pazvitsigiso inopiwa kugoverwa girisi mitsipa. Mipata iri pamatama uye mafuta ruchawira mumitsipa matanda. The mafuta zvikuru kunowedzera kusakara kuramba ari mugodhi zvikamu.
malfunctions
Nokuda mukuru mitoro, mashandiro ichi anokundikana. Pakati Mhando yezvikanganiso vangazivikanwa wakakurumidza kusakara pamusoro mumitsipa. Rinobatanidzwa zvinetso injini chinhu chinogumbura. Sezvo kazhinji chinoitika paanokudheerera mitsipa hunoonekwa. Izvi zvinoitika nokuda murombo wokufambisa kana kusava lubrication, kana maererano kutyora tembiricha ezvinhu. Anokwenya pamitsipa ari hukawanika zvinogona kuonekwa chaizvo kakawanda. Zvakakosha kusiyanisa mitswi kana makatsemuka kunotangira nokuda simbi kuneta. Zvinowanzoitika kurova kwehana uye vachikotama zvikamu. Izvi ndezvechokwadi kunyanya vysokooborotisty motokari injini. Chimwe chaiwo kukundikana - zvokutsauka kubva mumitsipa fekitari saizi yavo. Asi ichi ndicho zvoga mutoo kupfuura vamwe. Yeuka kuti kukura crankshaft vane kubvumirawo zvimwe kwete kupfuura 0.02 millimeters. Chero kusawirirana zvikaramba paburi pamusoro michina.
Maitirwo yokutsiva?
Zvechokwadi, mune dzimwe mhando yezvikanganiso kuita zvakagadzirwa - sanding kana buri. Asi dzimwe nguva hazvibviri kudzosa mugodhi. Muchiitiko chino, unogona kutsiva yekare ine mashandiro itsva. Panzira, injini ndiyo rokuti kupfuura zvinodhura. Kunyanya Diesel simba dzakabatana. Usati uchava yaitsiva crankshaft endplay ndakaongorora. Izvi zvichaita gadzirisa kusarudzwa zviri axial inoisa. Unofanira kuwana chiratidzo pamusoro liner uye humburumbira chinhu chinogumbura. Inoratidza kutungamirirwa kugadzwa crankshaft inobereka nguwani. All zvinhu kuti kudzivisa nekukatanura mugodhi, zvinofanira kubviswa. The kugadzira emirayiridzo dismantling kwacho chinorondedzerwa nenzira dzakasiyana, sezvo ari 8-ikakuruma uye 16-vharafu injini, ane mutsara kana V-zvakaumbwa humburumbira urongwa hurongwa. Zvino unofanira hwokugadza crankshaft hutsva yekare - zvakakosha zvikuru kuchengeta mirairo motokari mugadziri wacho uye hazvipindiri kukwira nzvimbo crankshaft. Nokuda mukuru basa ose basa rinofanira kuitwa unyanzvi pabasa.
Saka, isu akawana mudziyo, chinangwa uye nheyo crank nomubato motokari.
