Crank shaft.
Chinthu chofunika kwambiri cha injini. Zimatengera mphamvu kuchokera ku ndodo yolumikizira ndikuyisintha kukhala torque yotulutsa kudzera mu crankshaft ndikuyendetsa zida zina pa injini kuti zigwire ntchito. Crankshaft imakhudzidwa ndi mphamvu yozungulira ya centrifugal, mphamvu ya inertia ya gasi nthawi ndi nthawi komanso mphamvu yobwerezabwereza, yomwe imapangitsa crankshaft kunyamula katundu wopindika komanso wopindika. Chifukwa chake, crankshaft imafunika kuti ikhale ndi mphamvu zokwanira komanso kuuma, ndipo pamwamba pamagaziniyo sayenera kuvala, yunifolomu komanso yolinganiza.
Pofuna kuchepetsa kuchuluka kwa crankshaft ndi mphamvu yapakati yomwe imapangidwa poyenda, magazini ya crankshaft nthawi zambiri imakhala yopanda kanthu. Pamwamba pa magazini aliwonse amaperekedwa ndi bowo lamafuta kuti ayambitse kapena kutulutsa mafuta kuti azipaka mafuta pamasamba. Pofuna kuchepetsa kupsinjika maganizo, kulumikizana kwa khosi la spindle, pini ya crank ndi mkono wa crank zimalumikizidwa ndi arc transitional.
Ntchito ya crankshaft counterweight (yomwe imadziwikanso kuti counterweight) ndikuwongolera mphamvu yozungulira yapakati ndi mphindi yake, komanso nthawi zina mphamvu yobwerezabwereza komanso mphindi yake. Pamene mphamvu izi ndi mphindi zokha zili zoyenera, kulemera kwake kungagwiritsidwe ntchito kuchepetsa katundu pazitsulo zazikulu. Chiwerengero, kukula ndi kuyika kwa kulemera kwake ziyenera kuganiziridwa molingana ndi kuchuluka kwa masilindala a injini, makonzedwe a masilindala ndi mawonekedwe a crankshaft. Kulemera kwake nthawi zambiri kumaponyedwa kapena kupangidwa kukhala imodzi ndi crankshaft, ndipo kulemera kwa injini ya dizilo yamphamvu kwambiri kumapangidwa mosiyana ndi crankshaft kenako ndikumangirira pamodzi.
Kusungunula
Kupeza kutentha kwambiri komanso chitsulo chotsika cha sulfure ndi chinsinsi chopanga chitsulo chamtundu wapamwamba kwambiri. Zida zopangira zapakhomo zimachokera ku cupola, ndipo zitsulo zotentha sizingathetsere chithandizo cha desulfurization; Izi zimatsatiridwa ndi chitsulo chosayera kwambiri cha nkhumba komanso mtundu wochepa wa coke. Chitsulo chosungunula chimasungunuka mu cupola, sulfurized kunja kwa ng'anjo, ndiyeno kutenthedwa ndi kusinthidwa mu ng'anjo yolowera. Ku China, kudziwika kwa chitsulo chosungunuka nthawi zambiri kumachitika ndi vacuum molunjika kuwerenga spectrometer.
kuumba
Njira yopangira mlengalenga mwachiwonekere ndiyabwino kuposa njira yopangira mchenga wadongo, ndipo imatha kupeza ma crankshaft apamwamba kwambiri. Mchenga wopangidwa ndi njirayi umakhala ndi mawonekedwe osasinthika, omwe ndi ofunikira kwambiri pa crankshaft yamitundu yambiri. Ena opanga zoweta crankshaft ku Germany, Italy, Spain ndi mayiko ena kuti adziwe mpweya mmene akamaumba ndondomeko, koma kumayambiriro kwa mzere kupanga lonse ndi ochepa kwambiri opanga.
Kutulutsa kwa Electroslag
Ukadaulo wowongolera wa Electroslag umagwiritsidwa ntchito popanga crankshaft, kuti magwiridwe antchito a crankshaft afananize ndi crankshaft yonyengedwa. Ndipo ali ndi mawonekedwe akuyenda kwachitukuko chachangu, kuchuluka kwachitsulo chogwiritsidwa ntchito kwambiri, zida zosavuta, magwiridwe antchito apamwamba ndi zina zotero.
Kupanga tekinoloje
Mzere wodziwikiratu wokhala ndi makina osindikizira otentha ndi nyundo yamagetsi yamagetsi monga injini yayikulu ndi njira yopangira makina opangira crankshaft. Izi mizere kupanga zambiri kutengera umisiri zapamwamba monga kudula mwatsatanetsatane, mpukutu forging (mtanda mphero anagubuduza) kupanga, sing'anga pafupipafupi kupatsidwa ulemu Kutenthetsa, kutsiriza hayidiroliki atolankhani kutsirizitsa, etc. Pa nthawi yomweyo, ali okonzeka ndi makina othandizira monga manipulators, conveyor. malamba ndi zida zosinthira nkhungu zimabwereranso ku turntable kuti apange flexible production system (FMS). FMS imatha kusintha chogwiritsira ntchito ndikufa ndikusinthira magawo, ndikuyesa nthawi zonse pakugwira ntchito. Onetsani ndikujambulitsa deta monga makulidwe opangira ndi kukakamiza kwakukulu ndikufananiza ndi zikhalidwe zosasunthika kuti musankhe mapindikidwe abwino kwambiri azinthu zabwino. Dongosolo lonse limayang'aniridwa ndi chipinda chowongolera chapakati, ndikupangitsa kuti pakhale ntchito yopanda anthu. Crankshaft yopangidwa ndi njira yopangira iyi ili ndi ulusi wathunthu wa mzere wazitsulo wamkati, womwe ukhoza kuwonjezera mphamvu ya kutopa ndi 20%.
Ngati mukufuna kudziwa zambiri, pitilizani kuwerenga zolemba zina patsamba lino!
Chonde tiyimbireni ngati mukufuna zinthu zotere.
Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&MAUXS zolandiridwa kuti mugule.
