Kusweka kwa crankshaft
Ma fracture ambiri amapezeka pakati pa journal ndi crank arm. Zifukwa zake ndi izi: transition radius ndi yaying'ono kwambiri; radius sikonzedwa panthawi yotenthetsera, zomwe zimapangitsa kuti pakhale kupsinjika pa malo olumikizirana; radius imakonzedwa molakwika, ndi kusintha kwa magawo am'deralo; kugwira ntchito mopitirira muyeso kwa nthawi yayitali, ndipo ogwiritsa ntchito ena amawonjezera liwiro momwe akufunira kuti awonjezere kupanga, zomwe zimawonjezera vuto la kupsinjika; chinthucho chili ndi zolakwika, monga mabowo amchenga ndi kuchepera kwa casting. Kuphatikiza apo, ming'alu pa dzenje la mafuta pa crankshaft imathanso kuwoneka ikuyambitsa kusweka.
Kusanthula chifukwa cha zolakwika:
1. Ubwino woipa wa crankshaft
Ngati crankshaft si yoyambirira komanso yosakhala yabwino, ntchito yachangu ya excavator ingayambitse kuti crankshaft isweke mosavuta.
2. Ntchito yolakwika
Pa nthawi yogwira ntchito ya excavator, ngati throttle ndi yayikulu/yaing'ono kwambiri, imasintha, kapena excavator ikugwiritsidwa ntchito pa katundu wambiri kwa nthawi yayitali, crankshaft idzawonongeka ndi mphamvu yochulukirapo komanso kugundana, zomwe zimapangitsa kuti pakhale kusweka.
3. Kutseka mabuleki pafupipafupi mwadzidzidzi
Mukamagwiritsa ntchito excavator, ngati clutch pedal nthawi zambiri siipondedwa, brake yadzidzidzi imapangitsa kuti crankshaft isweke.
4. Maberani akuluakulu sali ofanana
Mukayika crankshaft, ngati mizere yapakati ya ma bearing akuluakulu pa silinda block siili yolunjika, pambuyo poti excavator yayatsidwa, zimakhala zosavuta kuyambitsa ma bearing kuyaka ndi shaft kumamatira, zomwe zimapangitsa kuti crankshaft isweke.
5. Mafuta oipa a crankshaft
Ngati pampu yamafuta yawonongeka kwambiri, mafuta sakupezeka mokwanira, kuthamanga kwa mafuta sikukwanira, ndipo njira yamafuta opaka mafuta ya injini yatsekedwa, crankshaft ndi bearing zidzakhala mu mkhalidwe wokangana kwa nthawi yayitali, zomwe zimapangitsa kuti crankshaft isweke.
6. Mpata pakati pa zigawo za crankshaft ndi waukulu kwambiri
Ngati mpata pakati pa crankshaft journal ndi bearing ndi waukulu kwambiri, crankshaft idzakhudza bearing pambuyo poti excavator yayamba kugwira ntchito, zomwe zimapangitsa kuti bearing ipse ndipo crankshaft iwonongeke.
7. Chingwe chowuluka chosasunthika
Ngati mabotolo a flywheel ndi omasuka, zigawo za crankshaft zidzataya mphamvu zawo zoyambirira ndikugwedezeka panthawi yogwiritsa ntchito excavator, zomwe zingayambitse mosavuta kumapeto kwa crankshaft kusweka.
8. Kusagwira ntchito bwino kwa silinda iliyonse
Ngati silinda imodzi kapena zingapo za chofukula sizikugwira ntchito, silinda sizili bwino, ndipo kupotoka kwa kulemera kwa gulu la ndodo yolumikizira pistoni ndi kwakukulu kwambiri, zidzapangitsanso kuti crankshaft isweke chifukwa cha mphamvu yosagwirizana.
9. Nthawi yoperekera mafuta isanafike nthawi yobereka
Ngati nthawi yoperekera mafuta yafika msanga, dizilo idzayaka pisitoni isanafike pakati, zomwe zingapangitse kuti crankshaft igwedezeke kwambiri. Ngati ntchitoyo ichitika motere kwa nthawi yayitali, crankshaft idzatopa ndikusweka.
10. Pisitoni yasweka ndipo yakakamizidwa kugwira ntchito
Ngati mphamvu yachepa ndipo pali phokoso losazolowereka mu silinda, pitirizani kugwira ntchito. N'zotheka kuti pisitoni yasweka, zomwe zimapangitsa kuti crankshaft itaye bwino, isinthe mawonekedwe kapena isweke mosavuta.
