I-crankshaft yeyona ndawo ijikelezayo ye-injini. Emva kokuba intonga yokudibanisa ifakwe, inokwenza i-up and down (i-reciprocating) intshukumo yentonga yokudibanisa kwaye iyiguqule ibe yi-cyclic (ejikelezayo) intshukumo.
Yinxalenye ebalulekileyo ye-injini. Izinto zayo zenziwe ngentsimbi ye-carbon structural okanye i-ductile iron. Inamacandelo amabini abalulekileyo: ijenali ephambili, ijenali yentonga yokudibanisa (kunye nabanye). Ijenali engundoqo ifakwe kwibhloko yesilinda, ijenali yentonga yokudibanisa idityaniswe nomngxuma omkhulu wentonga yokudibanisa, kwaye umngxuma omncinci wentonga yokudibanisa udityaniswe nepiston yesilinda, eyindlela eqhelekileyo yesilayidi. .
Itekhnoloji yokulungisa iCrankshaft
Nangona kukho iintlobo ezininzi ze-crankshafts kunye neenkcukacha zesakhiwo zahlukile, iteknoloji yokucubungula iyafana.
Intshayelelo yenkqubo ephambili
(1) Ukugaya kwangaphandle kwijenali ephambili yecrankshaft kunye nejenali yentonga yokudibanisa Ngexesha lokusetyenzwa kweengxenye zecrankshaft, ngenxa yempembelelo yesakhiwo sediski yokusila i-disc ngokwayo, umda wokusika kunye nesixhobo sokusebenza zihlala zinxibelelana ngethutyana kunye nomsebenzi, kwaye kukho impembelelo. Ngoko ke, ikhonkco lokucoca lilawulwa kuyo yonke inkqubo yokusika yesixhobo somatshini, okunciphisa ukungcangcazela okubangelwa ukukhutshwa kwentshukumo ngexesha lenkqubo yokucoca, ngaloo ndlela kuphuculwe ukuchaneka komatshini kunye nobomi benkonzo yesixhobo.
(2) Ukusila ijenali yecrankshaft engundoqo kunye nejenali yentonga yokudibanisa Indlela yokusila yokulandelela ithatha umgca osembindini wejenali engundoqo njengombindi wokujikelezisa, kwaye igqibezela ukusila kwejenali yentonga yokudibanisa i-crankshaft kwi-clamping enye (inokuthi isetyenziselwe undoqo. ukugaya ijenali), ukugawula Indlela yokusika iijenali zentonga yokudibanisa kukulawula ukutya kwevili lokusila kunye nonxibelelwano lwe-axis ezimbini zentshukumo ejikelezayo. yeworkpiece nge CNC ukugqiba ukutya kwe crankshaft. Indlela yokugaya yokulandelela ithatha i-clamping enye kwaye igqibe ukugaya ijenali ephambili ye-crankshaft kunye nejenali yentonga yokudibanisa ngokujika kumatshini wokusila we-CNC, onokunciphisa ngokufanelekileyo iindleko zezixhobo, ukunciphisa iindleko zokucubungula, kunye nokuphucula ukuchaneka kokusebenza kunye nokusebenza kakuhle kwemveliso.
(3) Ijenali ephambili yecrankshaft kunye nesixhobo somatshini wokudibanisa intonga yefillet isetyenziselwa ukuphucula amandla okudinwa kwe crankshaft. Ngokwezibalo, ubomi be-iron ductile crankshaft emva kwe-fillet rolling inokunyuswa nge-120% ukuya kwi-230%; ubomi be-crankshafts yentsimbi eyenziweyo emva kokuba i-fillet rolling inganyuswa nge-70% ukuya kwi-130%. Amandla okujikeleza okujikelezayo avela ekujikelezeni kwe-crankshaft, eqhuba i-roller kwi-rolling head ukuze ijikeleze, kwaye uxinzelelo lwe-roller luphunyezwa yi-cylinder yeoli.
