Ndife akatswiri pazigawo za injini zapamwamba kwambiri.
Chilankhulo
Kuthyoka kwa crankshaft nthawi zambiri kumakhala kuyambira koyambira kwa ming'alu yaying'ono, malo ophwanyidwa kwambiri amakhala mu silinda yamutu kapena kumapeto kwa silinda yolumikizira ndodo pakona yozungulira ndi gawo lolumikizira mkono. Pogwira ntchito, ming'aluyo imakula pang'onopang'ono ndipo imasweka mwadzidzidzi ikafika pamlingo winawake. Mu fracture pamwamba kuyang'ana nthawi zambiri adzapeza mbali ya bulauni, yomwe mwachiwonekere ndi mng'alu wakale, minofu yonyezimira imapangidwa kuti iwonongeke mwadzidzidzi. Lero, tiyeni tiwone chomwe chimayambitsa crankshaft fracture.

1. Makona ozungulira a crankshaft magazine ndi ochepa kwambiri
Pogaya CHIKWANGWANI, chopukusira chimalephera kuwongolera bwino fillet ya crankshaft. Kuphatikiza pa kukonza movutikira kwa arc pamwamba, ma radius a fillet ndi ochepa kwambiri, kotero kupsinjika kwa fillet kumakhala kwakukulu pamene crankshaft ikugwira ntchito, ndipo moyo wotopa wa crankshaft umafupikitsidwa.
2. crankshaft spindle axis offset
Kupatuka kwa crankshaft spindle neck axis kumawononga kusinthasintha kwa zida za crankshaft, ndipo mphamvu yamphamvu ya inertia imapangidwa injini ikathamanga kwambiri, zomwe zimapangitsa kuti crankshaft ithyoke.
3. mpikisano wozizira wa crankshaft ndi waukulu kwambiri
Crankshaft imagwiritsidwa ntchito kwa nthawi yayitali, makamaka pakachitika ngozi yakuwotcha matailosi kapena silinda yopumira, padzakhala kupindika kwakukulu, komwe kuyenera kutulutsidwa kuti kuwongolera kuzizira. Chifukwa mapindikidwe apulasitiki achitsulo amkati a crankshaft adzatulutsa kupsinjika kwakukulu kowonjezera pakuwongolera, kuti achepetse mphamvu ya crankshaft, ngati mpikisano wozizira ndi waukulu kwambiri, ukhoza kukhala crankshaft yomwe yawonongeka kapena kusweka, makina oyikawa. idzasweka mukangogwiritsa ntchito.
4. The flywheel yamasuka
Ngati bawuti ya flywheel imasuka, gulu la crankshaft lidzataya mphamvu yake yoyambira, ndipo injiniyo idzagwedezeka ikatha kugwira ntchito, ndikupanga mphamvu zambiri, zomwe zimapangitsa kuti crankshaft itope komanso kuthyoka mosavuta kumapeto kwa mchira.
5. tile ya spindle si coaxial
Pamsonkhano wa crankshaft, ngati mzere wapakati wa matailo a spindle pa silinda ya silinda si coaxial, injiniyo imatha kuwotcha matailosi ndikuchita ngozi ya shaft pambuyo pa ntchito, ndipo crankshaft imaswekanso chifukwa cha kupsinjika kwamphamvu.
6. Chilolezo cha crankshaft ndi chachikulu kwambiri
Ngati chilolezo pakati pa crankshaft magazine ndi chitsamba chokhala ndi chitsamba ndi chachikulu kwambiri, crankshaft imakhudza chitsamba injini ikatha, zomwe zimapangitsa kukhetsa kwa alloy ndikuwotcha matailosi okhala ndi shaft, ndipo crankshaft ndiyosavuta kuwonongeka.
7. nthawi yoperekera mafuta ndiyofulumira kwambiri kapena kuchuluka kwa mafuta pa silinda iliyonse sikuli kofanana
Ngati nthawi yoperekera mafuta pampu ya jakisoni ikayambika kwambiri, pisitoni sinagwirebe ntchito yoyaka ya TDC, imayambitsa kuphulika kwa injini, ndikupanga crankshaft ndi kupsinjika kwakusinthana. Ngati kuchuluka kwa mafuta operekedwa pa silinda iliyonse sikuli kofanana, mphamvu ya khosi lililonse la crankshaft idzakhala yosagwirizana chifukwa cha kuphulika kwamphamvu kwa silinda iliyonse, zomwe zimapangitsa kutopa msanga ndi ming'alu.
8. Mafuta a Crankshaft ndi abwino
Ngati mpope wamafuta wavala kwambiri, njira yamafuta opaka mafuta imakhala yodetsedwa ndipo kufalikira sikuli kosalala, kumapangitsa kuti mafuta azikhala osakwanira komanso kutsika kwamafuta, zomwe zimapangitsa kuti pakhale filimu yabwinobwino yopaka mafuta pakati pa crankshaft ndi kunyamula. chitsamba, zomwe zimabweretsa kugundana kowuma ndikupangitsa matailosi oyaka ogwirizira shaft, crankshaft yosweka ndi ngozi zina zazikulu.
9 . Opaleshoni yolakwika imayambitsa crankshaft fracture
Ngati throttle ndi yayikulu kwambiri kapena yaying'ono kwambiri, brake imakhala pafupipafupi kapena ntchito yolemetsa kwa nthawi yayitali, crankshaft imawonongeka ndi torque yayikulu kapena kuchuluka kwamphamvu. Kuonjezera apo, injini ya dizilo ikakhala ndi ngozi monga galimoto yowuluka, silinda ya ramming ndi valavu yapamwamba, zimakhala zosavuta kupanga crankshaft fracture.
