Crankshaft fracture
Nthawi zambiri zosweka zimachitika pakusinthana pakati pa magazini ndi mkono wa crank. Zifukwa zake ndi izi: malo osinthira ndi ochepa kwambiri; utali wozungulira si kukonzedwa pa kutentha kutentha, kumabweretsa kupsinjika maganizo pa mphambano; utali wozungulira amakonzedwa mosakhazikika, ndi masinthidwe am'deralo; ntchito yochulukira nthawi yayitali, ndipo ogwiritsa ntchito ena amawonjezera liwiro pakufuna kuti awonjezere kupanga, zomwe zimawonjezera kupsinjika; zinthu zomwezo zimakhala ndi zolakwika, monga mabowo a mchenga ndi kuchepa kwa kuponyera. Kuphatikiza apo, ming'alu pa dzenje lamafuta pa crankshaft imathanso kuwonedwa ndikupangitsa kuti maphwando aphwanyike.
Kusanthula kwazomwe zimayambitsa:
1. Ubwino wa crankshaft
Ngati crankshaft si yoyambirira komanso yosakhala bwino, kugwira ntchito mwachangu kwa chofufutira kungapangitse kuti crankshaft ithyoke mosavuta.
2. Kugwira ntchito molakwika
Pa ntchito yofukula, ngati throttle ndi yaikulu kwambiri / yaying'ono kwambiri, imasinthasintha, kapena chofukula chikugwiritsidwa ntchito pamtunda wautali kwa nthawi yaitali, crankshaft idzawonongeka ndi mphamvu zambiri ndi mphamvu, zomwe zimayambitsa kusweka.
3. Mabuleki pafupipafupi mwadzidzidzi
Mukamagwiritsa ntchito chofukula, ngati clutch pedal nthawi zambiri sichinapondedwe, kuphulika kwadzidzidzi kumapangitsa kuti crankshaft ithyoke.
4. Zigawo zazikulu sizili zogwirizana
Mukayika crankshaft, ngati mizere yapakati ya mayendedwe akuluakulu pa cylinder block siyikulumikizana, chofufutira chikayamba, zimakhala zosavuta kupangitsa kuti ma bearings awotche ndikumamatira, potero kupangitsa crankshaft kusweka.
5. Kusapaka mafuta a crankshaft
Ngati pampu yamafuta yavala kwambiri, mafuta sakhala okwanira, kuthamanga kwamafuta sikukwanira, ndipo njira yamafuta yothira mafuta yatsekedwa, crankshaft ndi kunyamula kumakhala kokangana kwa nthawi yayitali, kupangitsa crankshaft kusweka.
6. Kusiyana pakati pa crankshaft ndi kwakukulu kwambiri
Ngati kusiyana pakati pa crankshaft magazine ndi kunyamula kuli kwakukulu kwambiri, crankshaft idzakhudza momwe chofufutiracho chikuyenda, zomwe zimapangitsa kuti chibowo chiwotche ndi kuwonongeka kwa crankshaft.
7. Flywheel yotayirira
Ngati mabawuti a ma flywheel atayikira, mbali za crankshaft zimataya mphamvu yake yoyambira ndikugwedezeka panthawi yofukula, zomwe zingapangitse kuti kumapeto kwa mchira wa crankshaft kuthyoke.
8. Kusagwira ntchito bwino kwa silinda iliyonse
Ngati silinda imodzi kapena zingapo za chofukula sizikugwira ntchito, masilindala amakhala osalinganizika, ndipo kupatuka kwa gulu la ndodo yolumikizira pisitoni ndikokulirapo, kumapangitsanso crankshaft kusweka chifukwa cha mphamvu yosagwirizana.
9. Nthawi yofulumira kwambiri yoperekera mafuta
Ngati nthawi yoperekera mafuta ikakhala koyambirira kwambiri, dizilo imawotcha pisitoni isanafike pakatikati pakufa, zomwe zingapangitse crankshaft kukhudzidwa kwambiri ndi katundu. Ngati ntchitoyo ikuchitika motere kwa nthawi yayitali, crankshaft imatopa ndikusweka.
10. Pistoni yathyoka ndikukakamizika kugwira ntchito
Ngati mphamvu yamagetsi yachepetsedwa ndipo pali phokoso losamveka mu silinda, pitirizani kugwira ntchito. N'kutheka kuti pisitoni yathyoka, zomwe zimapangitsa kuti crankshaft iwonongeke, kupunduka kapena kusweka mosavuta.
