I-crankshaft, nokuba yi-crankshaft ye-injini yemoto, i-crankshaft ye-injini yaselwandle okanye i-crankshaft yempompo ye-industrial, ifumana isenzo esidityanisiweyo sokugoba kunye nokutshintshwa kwemithwalo ye-torsion ngexesha lenkqubo yokujikeleza. Amacandelo ayingozi e-crankshaft, ngakumbi i-fillet yenguqu phakathi kwejenali kunye ne-crank Ngamanye amaxesha, i-crankshaft fractures ngenxa yoxinzelelo oluphezulu loxinzelelo.

Ngoko ke, iimeko zenkonzo zifuna ukuba i-crankshaft ibe namandla okwaneleyo ukuqinisekisa ukuba i-crankshaft ayiphuli ngexesha lokusebenza. Okwangoku, ukusetyenziswa kwe-shot peening ukutshintsha ukumelana nokudinwa kwee-crankshafts kusetyenziswe ngokubanzi kuluhlu olubanzi lwezicelo, kwaye umphumo uyanelisa kakhulu.

Xa kuthelekiswa nesiphene senkqubo yokuqengqeleka yemveli, ngenxa yokuthintelwa kobuchwepheshe bokucwangcisa icrankshaft, iikona ezijikelezileyo zejenali nganye kunzima ukudibanisa nerola, nto leyo edla ngokubangela ukuqutyulwa kweekona ezingqukuva, kunye ne-crankshaft emva kokuqengqeleka. ikhubazeke kakhulu, ayisebenzi kakuhle. Indlela yokukroba kukusebenzisa iipellets ezinobukhulu obulawulwa ngokungqongqo kunye namandla athile ukwenza umjelo weepellets phantsi kwentshukumo yomoya ohamba ngesantya esiphezulu kwaye ngokuqhubekayo uzitshize kumphezulu wesinyithi we crankshaft, kanye njengokubethelwa ngehamile ngamancinci angenakubalwa. iihamile zokwenza umphezulu we-crankshaft Ukuvelisa ukuguqulwa kweplastiki eyomeleleyo kwaye wenze umsebenzi obandayo owenziwe lukhuni. Ukuyibeka ngokulula, ngenxa yokuba i-crankshaft iphantsi kweendlela ezahlukeneyo zokusika oomatshini ngexesha lokusetyenzwa, ukuhanjiswa koxinzelelo kumphezulu wayo, ngakumbi utshintsho lwecandelo lomnqamlezo we-crankshaft, alulingani kakhulu, kwaye luphantsi koxinzelelo olutshintshanayo ngexesha lomsebenzi, kulula Uxinzelelo lwe-corrosion kwaye ubomi bokudinwa kwe-crankshaft buyancipha. Inkqubo yokudubula i-peening kukwazisa uxinzelelo lwangaphambili lokunciphisa uxinzelelo oluya kufunyanwa ngumjikelo wokusebenza wexesha elizayo, 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 ulwahlulo lwamacandelo, iinkozo ezirhabaxa zesakhiwo sokuqala, kunye nokuhanjiswa kwesakhiwo sangaphakathi esingenangqiqo kwiindawo ezingenanto. Kwaye ezinye iziphene ze-metallurgical kunye nentlangano, ngaloo ndlela ukunciphisa ubomi bokukhathala kwe-crankshaft, inkqubo yokomeleza inokuphucula isakhiwo kunye nokuphucula kakhulu ukusebenza kwayo kokukhathala.
