Umsebenzi we-crankshaft ukuguqula umfutho wegesi osuka eqenjini lokuxhuma i-piston ube yi-torque ukuze uphume ngaphandle, kanye nokushayela isitimela samavalvu nezinye izinto ezisizayo. Iningi lazo lenziwe ngensimbi esezingeni eliphakeme ye-carbon, medium alloy carbon steel noma i-spheroidal graphite cast iron. Isakhiwo se-crankshaft sihlanganisa i-shaft yangaphambili, ijenali eyinhloko, ijenali yenduku exhumayo, i-crank, i-counterweight, shaft yangemuva, njll., futhi kukhona amaphaseji kawoyela agijima kujenali eyinhloko, i-crank kanye nejenali yenduku yokuxhuma ukuze kugcotshwe ijenali eyinhloko kanye nenduku yokuxhuma. . Ijenali. Ngenxa yokuthi izoba ngaphansi kwamandla ahlukahlukene asetshenziswayo, kuzoba nenani elithile lokuguga, futhi izingxenye ezihlukene zinezici ezihlukile zokugqoka.
Gqoka izici zejenali eyinhloko kanye nesihlahla esithwalayo esiyinhloko
Ukugqokwa kwejenali eyinhloko eduze kokuqondisa kwe-axial kufanele kufane, futhi inani lokugqoka endaweni ye-radial alilingani, futhi kuzoba ne-ellipticity encane. Njengoba ijenali emaphakathi ivamise ukuba ngaphansi kwamandla amakhulu, inani layo eligugayo livame ukuba likhulu kunalelo lalezi ziphetho ezimbili. Ukugqokwa kwe-radial kwesihlahla esithwalayo esiyinhloko kuhambisana nalokho kwejenali eyinhloko. Ingxenye yokugqoka enkulu kunazo zonke iku-bearing engezansi, futhi ukugqokwa kwesihlahla esithwalayo esiphakathi kukhulu kunaleyo yemikhawulo emibili.
Gqoka izici zejenali yenduku yokuxhuma kanye nesihlahla senduku yokuxhuma
Ukugqokwa kwe-radial kwamajenali wenduku yokuxhuma nama-bearings akulingani, futhi ukugqokwa ohlangothini lwangaphakathi kukhulu uma kuqhathaniswa. Ukugqoka okungalingani kubangela ukuthi ijenali yenduku yokuxhuma yakhe i-ellipse ethile endaweni ye-radial, futhi i-axial direction ivamise ukufana. Induku yokuxhuma enesakhiwo esinamaphethelo amakhulu a-asymmetric izoba tape ngemva kokuguga ngenxa yokusatshalaliswa komthwalo ongalingani kujenali yenduku yokuxhuma; induku yokuxhuma ene-symmetrical enkulu-end structure izobangela imiphumela efanayo uma igobile.
Ingxenye egqokwa kakhulu yejenali yenduku yokuxhuma ngokuvamile ingaphakathi kwejenali ngayinye, okungukuthi, ohlangothini lwe-centerline crankshaft, ukuze ijenali iphume nxazonke; futhi ingxenye egqoka ikhoni ngokuvamile iseceleni kwephaseji likawoyela wokugcoba lapho ukungcola kunamathiselwe khona. Ehlangothini kanye nendawo lapho amandla amakhulu.
Ukuguga kwe-crankshaft kungalinganiswa nge-micrometer. Ukuguga kwejenali emfishane ye-crankshaft kufanele kuhlolwe ikakhulukazi amaphutha okujikeleza, futhi kumajenali amade, amaphutha okujikeleza kanye nama-cylindricity kufanele ahlolwe. Indlela yokulinganisa ethize yilena: thatha izigaba ezimbili zejenali ngayinye, bese uthatha amaphuzu amabili esigabeni ngasinye. Ingxenye yomehluko phakathi kobukhulu obukhulu kanye nobubanzi obuncane besigaba esifanayo yiphutha lokuyindilinga; uhhafu womehluko phakathi kobukhulu obukhulu kanye nobubanzi obuncane ezingxenyeni ezimbili yiphutha le-cylindricity. Ngaphansi kwezimo ezijwayelekile zokusebenza, ukuguga kwe-crankshaft kuncane kakhulu, ngokuvamile akudluli ku-0.01mm, futhi isilinda singaphansi kuka-0.0025mm.
Izinhlobo ezijwayelekile zokulimala kwe-crankshaft zifaka phakathi ukuguga kwejenali, ukuqhekeka, ukusha, ukugoba noma ukuphuka, njll. Singahlaziya isimo sokusebenza kwenjini kanye nembangela yomonakalo ngenxa yokuguga kwe-crankshaft. Isibonelo, inani lokugqoka kwe-crankshaft likhulu kakhulu, futhi isihlahla esithwalayo sivuza ngisho nombala wangemuva. Lesi simo ngokuvamile sibangelwa ukugcotshwa okungekuhle, umfutho kawoyela ophansi, kanye nowoyela ongahlangabezani nezidingo zokusetshenziswa. I-crankshaft cylinder inkulu kakhulu, okukhombisa ukuthi injini isinesikhathi eside isebenza ngaphansi komthwalo osindayo. ; Ukusha kwe-crankshaft, blues, locks, kumele kubangelwe ukungagcobi kahle, okuvame kakhulu ukuntuleka kwamafutha.
