Kodi crankshaft ndi chiyani?Kodi crankshaft imachita chiyani?Kapangidwe ka crankshaft?
Crankshaft ndi imodzi mwazinthu zofunika kwambiri za injini, zimatengera mphamvu kuchokera ku ndodo yolumikizira ndikuyisintha kukhala torque 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 zowuma, ndipo pamwamba pamagaziniyo sayenera kuvala, yunifolomu komanso moyenera.Crankshaft imapangidwa ndi chitsulo cha carbon structural kapena ductile iron, ndipo ndodo yolumikizira ikayikidwa, imatha kunyamula kusuntha ndi kutsika (kubwereza) kwa ndodo yolumikizira, ndikuisintha kukhala yozungulira (yozungulira).Ntchito yaikulu ya crankshaft ndikusintha kayendedwe ka injini mmwamba ndi pansi kuti ikhale yozungulira, motero kupereka mphamvu ku makina onse.
Udindo wa crankshaft makamaka umaphatikizapo mfundo zotsatirazi:
Mphamvu yotumizira: Crankshaft imasamutsa mphamvu ya pisitoni kupita ku shaft yotulutsa potembenuza pisitoni yobwerezabwereza kuti ikhale yozungulira yozungulira, ndikuyendetsa mbali zina za injini kuti zigwire ntchito, monga ma valve, ma pistoni, ndodo zolumikizira, ndi zina zambiri. .
Transfer torque ndi liwiro: Crankshaft imathanso kusamutsa ma torque ndi liwiro la injini kupita ku shaft yotulutsa, kuti galimotoyo ipange mphamvu poyendetsa, kuti injiniyo izigwira ntchito bwino.
Kulimbana ndi torque: Crankshaft iyeneranso kupirira ma torque ndi mphamvu ya injini kuti iwonetsetse kuti injini ikugwira ntchito bwino.
Valve yowongolera: Crankshaft imayendetsa mpweya wolowa ndi kutulutsa mpweya mu silinda mwa kuyang'anira kutsegula ndi kutseka kwa valve kuti zitsimikizire kuti injini ikuyenda bwino.
Nthawi zambiri, crankshaft ndi imodzi mwamagawo ofunikira kwambiri a injini, ntchito yake ndikutembenuza kusuntha kwa piston kukhala kuzungulira kozungulira kwa crankshaft kuyendetsa mbali zina za injini kuti zigwire ntchito, komanso kufunikira kupirira mphamvu zosiyanasiyana ndi mphindi kuonetsetsa ntchito bwinobwino injini.
Crankshaft makamaka imakhala ndi zigawo izi:
Khosi la Spindle: Gawo lalikulu lothandizira la crankshaft, lothandizidwa ndi chonyamulira chachikulu munyumba yayikulu ya crankcase.Mzere wa khosi la spindle uli mu mzere wowongoka womwewo.
Connecting rod magazine (crank pini) : kuchoka ku nsonga ya shaft magazine yaikulu kuti muyike magazini yolumikizira ndodo, ndipo pali Angle ina pakati pa ndodo yolumikizira kuti mutembenuzire mphamvu kuchokera ku ndodo yolumikizira kukhala torque yozungulira ya crankshaft. .
Crank (crank arm) : Gawo lomwe limalumikiza magazini yolumikizira ndodo ndi shaft magazine yayikulu kuti isinthe mphamvu kuchokera ku ndodo yolumikizira kupita ku torque yozungulira ya crankshaft.
Counterweight: amagwiritsidwa ntchito kulinganiza torque ya centrifugal ya injini, ndipo nthawi zina kulinganiza mbali ya mphamvu yobwerezabwereza kuti crankshaft izungulire bwino.
Shaft-kumapeto (mapeto aulere): amagwiritsidwa ntchito kukhazikitsa pulley yamadzi, crankshaft timing pulley, etc.
Kumbuyo kwa flange: komwe kumagwiritsidwa ntchito kuyika flywheel, magazini yakumbuyo yakumbuyo ndi flywheel flange pakati pa mafuta flange ndi ulusi wobwerera, kuteteza mafuta kuti asabwerere.
Mfundo yogwirira ntchito ya crankshaft imaphatikizapo kutembenuza mphamvu kuchokera ku ndodo yolumikizira kukhala torque, yomwe imachokera ku crankshaft ndikuyendetsa zida zina pa injini kuti zigwire ntchito.Pochita izi, crankshaft imakhudzidwa ndi mphamvu ya centrifugal ya misa yozungulira, mphamvu ya inertia ya gasi yosintha nthawi ndi nthawi komanso mphamvu yobwerezabwereza, ndipo imakhala ndi mphamvu yopindika ndi yopingasa.Chifukwa chake, crankshaft imayenera kukhala ndi mphamvu zokwanira komanso kuuma, ndipo pamwamba pa magaziniyi iyenera kukhala yosagwira ntchito, yofananira komanso yolinganiza.
