Kutsemuka kwemuchina wecrankshaft
Mazhinji emaputsika anoitika panguva yekuchinjana pakati pejournal ne crank arm. Zvikonzero ndeizvi: transition radius idiki kwazvo; radius haigadziriswe panguva yekupisa, zvichikonzera kushushikana kwakanyanya panosangana; radius inogadziriswa zvisina kurongeka, nekuchinja kwenzvimbo; kushanda kwenguva refu, uye vamwe vashandisi vanowedzera kumhanya pavanoda kuti vawedzere kugadzirwa, izvo zvinowedzera kushushikana; chinhu chacho chine zvikanganiso, zvakaita semaburi ejecha uye kupwanyika kwemuchina. Pamusoro pezvo, maburi ari paburi remafuta pa crankshaft anogonawo kuonekwa achikonzera kupwanyika.
Kuongorora chikonzero chemhosva:
1. Hunhu husina kunaka hwecrankshaft
Kana crankshaft isiri yepakutanga uye isina kunaka, kushanda nekukurumidza kwemuchina wekuchekerera kunogona kukonzera kuti crankshaft ityoke zviri nyore.
2. Kushanda zvisina kunaka
Munguva yekushanda kwemuchimbuzi, kana throttle yakakura/diki zvakanyanya, ikachinja-chinja, kana kuti muchimbuzi chikashandiswa nesimba rakawanda kwenguva yakareba, crankshaft ichakuvadzwa nesimba rakawandisa uye kurova, zvichikonzera kutyoka.
3. Kugara uchibhureka nekukurumidzira
Pakushandisa excavator, kana clutch pedal isingawanzo tsikwa, emergency braking ichaita kuti crankshaft ityoke.
4. Mabheyaringi makuru haana kurongeka
Pakuisa crankshaft, kana mitsetse yepakati yemabearing main pa cylinder block isina kurongeka, mushure mekunge excavator yatanga, zviri nyore kuti mabearing apise uye shaft inamire, zvichiita kuti crankshaft ityoke.
5. Kunyorovesa crankshaft kusina kunaka
Kana pombi yemafuta yakasakara zvakanyanya, mafuta asina kukwana, kumanikidzwa kwemafuta hakuna kukwana, uye nzira yemafuta ekuzora injini yakavharika, crankshaft nebearing zvichave mumamiriro ekukweshana kwenguva yakareba, zvichiita kuti crankshaft ityoke.
6. Mukana uri pakati pezvikamu zve crankshaft wakakura zvakanyanya
Kana mukaha uri pakati pe crankshaft journal ne bearing wakakura zvakanyanya, crankshaft ichakanganisa bearing mushure mekunge excavator yatanga kushanda, zvichiita kuti bearing itsve uye crankshaft ikuvare.
7. Chivharo chendege chakasununguka
Kana mabhaudhi e flywheel akasununguka, zvikamu zve crankshaft zvinorasikirwa nechiyero chazvo chepakutanga uye zvinozununguka panguva yekushanda kwe excavator, izvo zvinogona kukonzera nyore nyore kuti magumo emuswe we crankshaft aputsike.
8. Kushanda zvisina kuenzana kwesirinda yega yega
Kana sirinda imwe kana kupfuura dzemuchina wekuchekerera dzisiri kushanda, sirinda dzisina kuenzana, uye kutsauka kwehuremu hweboka retsvimbo yekubatanidza piston kwakakura zvakanyanya, zvichaitawo kuti crankshaft ityoke nekuda kwesimba risina kuenzana.
9. Nguva yekuwanikwa kwemafuta isati yakwana
Kana nguva yekupihwa kwemafuta iri pamberi, dhiziri rinotanga kupisa piston isati yasvika pakati pemoto, izvo zvinoita kuti crankshaft iite crankshaft yakakura uye mutoro. Kana basa iri rikaitwa nenzira iyi kwenguva yakareba, crankshaft ichaneta uye ichatyoka.
10. Pistoni yatyoka uye yamanikidzwa kushanda
Kana simba remagetsi radzikira uye ruzha rwusina kujairika rwuri mu cylinder, ramba uchishanda. Zvingangoita kuti piston yakatyoka, zvichiita kuti crankshaft irasikirwe nechiyero, ikanganise kana kutyoka zviri nyore.
