I-crankshaft iyingxenye eyinhloko yenjini ezungezayo. Ngemva kokuba induku yokuxhuma ifakiwe, ingakwazi ukwenza ukunyakaza okuya phezulu naphansi (okuphindaphindayo) kwenduku yokuxhuma futhi iyiguqule ibe ukunyakaza kwe-cyclic (ejikelezayo).
Iyingxenye ebalulekile yenjini. Izinto zayo zenziwe ngensimbi ye-carbon structural noma i-ductile iron. Inezingxenye ezimbili ezibalulekile: ijenali eyinhloko, ijenali yenduku yokuxhuma (nokunye). Ijenali eyinhloko ifakwe ku-cylinder block, ijenali yenduku yokuxhuma ixhunywe nembobo enkulu yokugcina yenduku yokuxhuma, futhi imbobo encane yokugcina yenduku yokuxhuma ixhunywe ne-cylinder piston, okuwumshini ojwayelekile we-crank-slider. .
Ubuchwepheshe bokucubungula i-Crankshaft
Nakuba kunezinhlobo eziningi zama-crankshaft futhi eminye imininingwane yesakhiwo ihlukile, ubuchwepheshe bokucubungula bucishe bufane.
Isethulo senqubo eyinhloko
(1) Ukugaya kwangaphandle kwejenali eyinhloko ye-crankshaft kanye nejenali yenduku yokuxhuma Ngesikhathi sokucutshungulwa kwezingxenye ze-crankshaft, ngenxa yethonya lesakhiwo se-disc milling cutter ngokwayo, unqenqema lokusika kanye nocezu lokusebenza kuhlale kuthintana nezikhawu ne-workpiece, futhi kunomthelela. Ngakho-ke, isixhumanisi sokusula silawulwa kulo lonke uhlelo lokusika lwethuluzi lomshini, okunciphisa ukudlidliza okubangelwa imvume yokunyakaza ngesikhathi senqubo yomshini, ngaleyo ndlela kuthuthukiswe ukunemba kwemishini kanye nempilo yesevisi yethuluzi.
(2) Ukugaya ijenali eyinhloko ye-crankshaft kanye nejenali yenduku yokuxhuma Indlela yokugaya yokulandelela ithatha umugqa omaphakathi wejenali eyinhloko njengendawo ephakathi yokuzungezisa, futhi iqedelela ukugaywa kwejenali yenduku yokuxhuma i-crankshaft ekubambeni okukodwa (ingase futhi isetshenziselwe okuyinhloko ukugaya ijenali), ukugaya Indlela yokusika amajenali enduku yokuxhuma ukulawula ukuphakela kwesondo lokugaya kanye nokuxhunywa kwama-eksisi amabili okunyakaza okujikelezayo. we-workpiece ngokusebenzisa i-CNC ukuqedela ukuphakela kwe-crankshaft. Indlela yokugaya yokulandelela isebenzisa i-clamping eyodwa futhi iqedela ukugaywa kwejenali eyinhloko ye-crankshaft kanye nejenali yenduku yokuxhuma ivule umshini wokugaya we-CNC, onganciphisa ngempumelelo izindleko zemishini, unciphise izindleko zokucubungula, futhi uthuthukise ukunemba kokucubungula nokusebenza kahle kokukhiqiza.
(3) Ijenali eyinhloko ye-crankshaft kanye nethuluzi lomshini wokugoqa we-fillet ye-rod isetshenziselwa ukuthuthukisa amandla okukhathala kwe-crankshaft. Ngokwezibalo, impilo ye-ductile iron crankshaft ngemuva kokugoqa i-fillet ingakhuphuka ngo-120% kuya ku-230%; Impilo yama-crankshafts ensimbi akhiwe ngemuva kokugingqika kwe-fillet ingakhuphuka ngo-70% iye ku-130%. Amandla ajikelezayo we-rolling avela ekujikelezeni kwe-crankshaft, okushayela ama-roller ekhanda eligoqayo ukuze ajikeleze, futhi ukucindezela kwama-roller kwenziwa yi-cylinder yamafutha.
