Umngxuma we-crank.
Eyona nto ibalulekileyo kwinjini. Ithatha amandla kwinduku yokudibanisa ize iyiguqule ibe yi-torque output nge-crankshaft ize iqhubele ezinye izixhobo kwinjini ukuba zisebenze. I-crankshaft ichatshazelwa ngamandla e-centrifugal obunzima obujikelezayo, amandla e-inertia yegesi aphindaphindayo kunye namandla e-inertia aphindaphindayo, okwenza i-crankshaft ithwale isenzo sokugoba kunye nomthwalo we-torsional. Ke ngoko, i-crankshaft iyadingeka ukuba ibe namandla aneleyo kunye nokuqina, kwaye umphezulu wejenali kufuneka ungagugi, ufane kwaye ulungelelane.
Ukuze kuncitshiswe ubunzima be-crankshaft kunye namandla e-centrifugal aveliswayo ngexesha lokuhamba, i-crankshaft journal idla ngokuba yi-hole. Umphezulu ngamnye we-journal unikwa umngxuma weoyile wokungenisa okanye wokukhupha ioyile ukuze kuthanjiswe umphezulu we-journal. Ukuze kuncitshiswe uxinzelelo, uqhagamshelo lwentamo ye-spindle, i-crank pin kunye nengalo ye-crank ziqhagamshelwe yi-arc yenguqu.
Indima ye-crankshaft counterweight (ekwaziwa ngokuba yi-counterweight) kukulinganisela amandla e-centrifugal ajikelezayo kunye nomzuzu wayo, kwaye ngamanye amaxesha amandla e-inertial aphindaphindayo kunye nomzuzu wayo. Xa la mandla kunye namaxesha ngokwawo elinganisiwe, ubunzima bebhalansi bungasetyenziselwa ukunciphisa umthwalo kwi-bearing ephambili. Inani, ubungakanani kunye nokubekwa kobunzima bebhalansi kufuneka kuqwalaselwe ngokwenani lee-cylinders zenjini, ulungiselelo lwee-cylinders kunye nokuma kwe-crankshaft. Ubunzima bebhalansi ngokubanzi buphonswa okanye buhlanganiswe kunye ne-crankshaft, kwaye ubunzima bebhalansi yenjini yedizili enamandla aphezulu benziwa ngokwahlukileyo kwi-crankshaft kwaye emva koko bahlanganiswe kunye.
Ukunyibilikisa
Ukufumana isinyithi esishushu esishushu esishushu esinobushushu obuphezulu kunye nesalfure ephantsi yeyona nto iphambili ekuveliseni isinyithi esithambileyo esikumgangatho ophezulu. Izixhobo zemveliso zasekhaya zisekelwe ikakhulu kwi-cupola, kwaye isinyithi esishushu asiyondlela yonyango lwangaphambi kokususwa kwe-sulfurization; Oku kulandelwa yintsimbi yehagu engacocekanga kangako kunye nomgangatho ophantsi we-coke. Isinyithi esinyibilikisiweyo siyanyibilikiswa kwi-cupola, sisuswe i-sulfur ngaphandle kwesithando, size emva koko sifudunyezwe kwaye silungiswe kwisithando sokungenisa. E-China, ukufunyanwa kwesinyithi esinyibilikisiweyo kuye kwenziwa ngokubanzi nge-vacuum direct reading spectrometer.
ukubumba
Inkqubo yokubumba impembelelo yomoya ngokucacileyo ingcono kunenkqubo yokubumba isanti yodongwe, kwaye inokufumana ii-crankshaft castings ezichanekileyo kakhulu. I-sand mold eveliswa yile nkqubo ineempawu zokungaguquguquki kwe-rebound, nto leyo ebaluleke kakhulu kwi-crankshaft ephoswa nge-multi-throw. Abanye abavelisi be-crankshaft basekhaya abavela eJamani, e-Itali, eSpain nakwamanye amazwe ukwazisa inkqubo yokubumba impembelelo yomoya, kodwa ukungeniswa komgca wonke wemveliso linani elincinci kakhulu labavelisi.
Ukuphoswa kwe-Electroslag
Itekhnoloji yokutshintsha i-electroslag isetyenziswa ekuvelisweni kwe-crankshaft, ukuze ukusebenza kwe-crankshaft ephosiweyo kufane noko kwe-crankshaft eyenziweyo. Kwaye ineempawu zomjikelo wophuhliso olukhawulezayo, izinga eliphezulu lokusetyenziswa kwesinyithi, izixhobo ezilula, ukusebenza okuphezulu kwemveliso njalo njalo.
Itekhnoloji yokubumba
Umgca ozenzekelayo one-hot die forging press kunye ne-electric hammer hydraulic njengenjini ephambili yindlela yophuhliso lwemveliso ye-crankshaft. Le migca yemveliso ngokubanzi iya kusebenzisa ubuchwepheshe obuphambili obufana nokusika ngokuchanekileyo, ukwenza i-roll forging (cross wedge rolling), ukufudumeza i-medium frequency induction, ukugqiba i-hydraulic press finishing, njl. Kwangaxeshanye, baxhotyiswe ngoomatshini abancedisayo abanjengee-manipulators, ii-conveyor belts kunye nezixhobo zokutshintsha i-mold ezibuyiselwe kwi-turntable ukuze zenze inkqubo yokuvelisa eguquguqukayo (i-FMS). I-FMS inokutshintsha ngokuzenzekelayo i-workpiece kwaye ife kwaye ilungise ngokuzenzekelayo iiparameter, kwaye ihlale ilinganisa ngexesha lokusebenza. Bonisa kwaye urekhode idatha efana nobukhulu be-forging kunye noxinzelelo oluphezulu kwaye uthelekise namaxabiso azinzileyo ukuze ukhethe i-deformation engcono kakhulu yeemveliso ezisemgangathweni. Yonke inkqubo ijongwa liqela lolawulo eliphakathi, okwenza ukuba ukusebenza kungabikho mntu. I-crankshaft eyenziwe ngale ndlela ye-forging ine-fiber epheleleyo yomgca we-internal metal flow, enokunyusa amandla okudinwa ngaphezulu kwe-20%.
