I-crankshaft, nokuba yi-crankshaft ye-injini yemoto, i-crankshaft ye-injini yaselwandle okanye i-crankshaft yempompo ye-industrial, iphantsi kwesenzo esidityanisiweyo sokugoba kunye nokutshintshwa kwemithwalo ejikelezayo ngexesha lenkqubo yokujikeleza. Amacandelo ayingozi e-crankshaft, ngakumbi i-fillet yenguqu phakathi kwejenali kunye ne-crankshaft. Ngeli xesha, i-crankshaft idla ngokuphuka ngenxa yoxinzelelo oluphezulu loxinzelelo. Ngoko ke, iimeko zenkonzo zifuna ukuba i-crankshaft ibe namandla okwaneleyo ukuqinisekisa ukuba i-crankshaft ayiphuli ngexesha lokusebenza. Okwangoku, ukutshintsha ukudinwa kwe-crankshaft ngokukroba kusetyenziswe ngokubanzi kuluhlu olubanzi, kwaye umphumo uyanelisa kakhulu.

Xa kuthelekiswa neziphene zenkqubo yemveli yokuqengqeleka, oko kukuthi, ngenxa yokuthintelwa kwetekhnoloji yokucubungula i-crankshaft, iikona ezijikelezileyo zejenali nganye kunzima ukuthelekisa iirola, ezidla ngokubangela ukuba kwenzeke into yokuluma nokusika iikona ezijikelezileyo, kwaye i-crankshaft emva kokuqengqeleka ikhubazekile kakhulu. ,hayi ngempumelelo. Indlela yokukroba kukusebenzisa amasuntswana adutyulwayo anobukhulu obulawulwa ngokungqongqo kunye namandla athile. Ngaphantsi kwesenzo sokuhamba komoya ohamba ngesantya esiphezulu, ukuhamba kwembumbulu kuyenziwa kwaye kutshizwe ngokuqhubekayo kumphezulu wesinyithi we-crankshaft, njengokubethelwa kweehamile ezincinci ezingenakubalwa, ukuze umphezulu we-crankshaft ubethelwe ngesando. Ivelisa uguquko lweplastiki eyomeleleyo, yenza umaleko obandayo wokuqina. Ngamagama alula, ngenxa yokuba i-crankshaft ixhomekeke kumandla ohlukeneyo okusika oomatshini ngexesha lokucutshungulwa, ukuhanjiswa koxinzelelo kumphezulu wayo, ngakumbi kwi-fillet yotshintsho lwecandelo le-crankshaft, ayilingani kakhulu, kwaye iphantsi koxinzelelo olutshintshanayo ngexesha lomsebenzi, Kulula ukuStressa umhlwa kwaye ubomi bokudinwa kwe crankshaft buyancipha. Inkqubo ye-shot peening kukuphelisa uxinzelelo oluya kuthi lube phantsi kwamacandelo kumjikelo wokusebenza olandelayo ngokuzisa uxinzelelo lwangaphambili, ngaloo ndlela kuphuculwe ukumelana nokudinwa kunye nobomi benkonzo obukhuselekileyo bomsebenzi.

Ukongezelela, i-crankshaft forging blanks yenziwe ngokuthe ngqo kwi-ingots yensimbi okanye ifakwe kwintsimbi eshushu. Ukuba iinkqubo zokubunjwa kunye nokuqengqeleka azilawulwa ngokufanelekileyo, kuya kuhlala kukho ukwahlulwa kwecandelo kwiindawo ezingenanto, iinkozo ezirhabaxa zesakhiwo sokuqala, kunye nokusabalalisa okungenangqiqo kwezakhiwo zangaphakathi. kunye nezinye iziphene ze-metallurgical kunye nentlangano, ngaloo ndlela ukunciphisa ubomi bokukhathala kwe-crankshaft, kunye nenkqubo yokomeleza inokuphucula ubume bentlangano kunye nokuphucula kakhulu ukusebenza kwayo kokukhathala.
