Shaft ya crank.
Gawo lofunika kwambiri la injini. Limatenga mphamvu kuchokera ku ndodo yolumikizira ndikuisintha kukhala mphamvu yotulutsa mphamvu kudzera mu crankshaft ndikuyendetsa zowonjezera zina pa injini kuti zigwire ntchito. Crankshaft imakhudzidwa ndi mphamvu ya centrifugal ya kulemera kozungulira, mphamvu ya mpweya wozungulira komanso mphamvu ya inertia yobwerezabwereza, zomwe zimapangitsa crankshaft kukhala ndi mphamvu yopindika komanso yozungulira. Chifukwa chake, crankshaft imafunika kukhala ndi mphamvu zokwanira komanso zolimba, ndipo pamwamba pake payenera kukhala polimba, pofanana komanso molingana.
Pofuna kuchepetsa kulemera kwa crankshaft ndi mphamvu ya centrifugal yomwe imapangidwa panthawi yoyenda, crankshaft journal nthawi zambiri imakhala yopanda kanthu. Pamwamba pa journal iliyonse pali dzenje la mafuta loti mafuta alowetsedwe kapena kuchotsedwa kuti alowetse pamwamba pa journal. Pofuna kuchepetsa kupsinjika, kulumikizana kwa khosi la spindle, crank pin ndi mkono wa crank zimalumikizidwa ndi transitional arc.
Ntchito ya crankshaft counterweight (yomwe imadziwikanso kuti counterweight) ndikulinganiza mphamvu yozungulira ya centrifugal ndi mphindi yake, ndipo nthawi zina mphamvu yobwerezabwereza ya inertial ndi mphindi yake. Pamene mphamvu ndi mphindi izi zili bwino, kulemera kwa balance kungagwiritsidwenso ntchito kuchepetsa katundu pa bearing yayikulu. Chiwerengero, kukula ndi malo a balance weight ziyenera kuganiziridwa malinga ndi chiwerengero cha masilinda a injini, kapangidwe ka masilinda ndi mawonekedwe a crankshaft. Kulemera kwa balance nthawi zambiri kumapangidwa kapena kupangidwa kukhala chimodzi ndi crankshaft, ndipo kulemera kwa balance ya injini ya dizilo yamphamvu kwambiri kumapangidwa mosiyana ndi crankshaft kenako kumangiriridwa pamodzi.
Kusungunula
Kupeza chitsulo chotentha chotentha kwambiri komanso sulfure yochepa ndiye chinsinsi chopangira chitsulo chapamwamba kwambiri. Zipangizo zopangira m'nyumba zimadalira kwambiri cupola, ndipo chitsulo chotentha sichimachiritsidwa ndi desulfurization; Izi zimatsatiridwa ndi chitsulo cha nkhumba chosayera kwambiri komanso coke yoipa. Chitsulo chosungunuka chimasungunuka mu cupola, chimachotsedwa sulfur kunja kwa ng'anjo, kenako chimatenthedwa ndikusinthidwa mu induction flooring. Ku China, kuzindikira kapangidwe ka chitsulo chosungunuka nthawi zambiri kumachitika pogwiritsa ntchito vacuum direct reading spectrometer.
kuumba
Njira yopangira mpweya wokhudza kukhudza ndi yabwino kwambiri kuposa njira yopangira mchenga wa dongo, ndipo imatha kupeza ma crankshaft castings olondola kwambiri. Nkhungu yamchenga yomwe imapangidwa ndi njirayi ili ndi makhalidwe osasinthika, zomwe ndizofunikira kwambiri pa crankshaft yoponya yambiri. Opanga ena a crankshaft ochokera ku Germany, Italy, Spain ndi mayiko ena kuti ayambe njira yopangira mpweya wokhudza kukhudza, koma kuyambitsa mzere wonse wopanga ndi ochepa kwambiri opanga.
Kuponya kwa Electroslag
Ukadaulo wochotsa zitsulo pogwiritsa ntchito ma electroslag umagwiritsidwa ntchito popanga crankshaft, kotero kuti magwiridwe antchito a crankshaft yopangidwa ndi anthu akhoza kufanana ndi a forged crankshaft. Ndipo ili ndi mawonekedwe a kupanga mwachangu, kugwiritsa ntchito zitsulo mopitirira muyeso, zida zosavuta, magwiridwe antchito apamwamba azinthu ndi zina zotero.
Ukadaulo wopanga
Mzere wodziyimira wokha wokhala ndi makina otenthetsera otentha komanso nyundo yamagetsi ya hydraulic monga injini yayikulu ndiye njira yopangira makina ophikira. Mizere yopangirayi nthawi zambiri imagwiritsa ntchito ukadaulo wapamwamba monga kudula molondola, kupanga ma roll (cross wedge rolling), kutentha kwapakati pafupipafupi, kumaliza makina ophikira a hydraulic, ndi zina zotero. Nthawi yomweyo, ali ndi makina othandizira monga manipulators, ma conveyor lamba ndi zida zosintha nkhungu zomwe zimabweretsedwa ku turntable kuti apange makina osinthika opangira (FMS). FMS imatha kusintha yokha workpiece ndikuyimitsa ndikusintha zokha magawo, ndikuyezera nthawi zonse panthawi yogwira ntchito. Onetsani ndikulemba deta monga makulidwe a forging ndi kuthamanga kwakukulu ndikuyerekeza ndi mitengo yokhazikika kuti musankhe kusintha kwabwino kwambiri kwa zinthu zabwino. Dongosolo lonse limayang'aniridwa ndi chipinda chowongolera chapakati, zomwe zimathandiza kuti ntchito yopanda munthu igwire ntchito. Crankshaft yopangidwa ndi njira iyi yophikira ili ndi ulusi wonse wa mzere wamkati wachitsulo, womwe ungawonjezere mphamvu yotopa ndi zoposa 20%.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
