Ihlanganisani i-piston assembly?
Umhlangano we-piston uyingxenye ebalulekile yenjini yemoto, eyakhiwe ikakhulukazi izingxenye eziyisithupha ezilandelayo:
1. I-Piston: Iyingxenye yegumbi elivuthayo futhi ifakwe ama-ring grooves amaningana ukufaka indandatho yepiston.
2. I-piston ring: Ifakwa ku-piston ukuze ivalwe, ngokuvamile eyakhiwe ngeringi yegesi nendandatho kawoyela.
3. Iphinikhodi ye-piston: Ukuxhuma i-piston nekhanda elincane le-piston rod yokuxhuma, kunezindlela ezimbili zokuntanta okugcwele kanye ne-semi-floating.
4. Induku yokuxhuma i-piston: induku yokuxhuma ye-piston ne-crankshaft, ihlukaniswe yaba ikhanda elikhulu nekhanda elincane ezinhlangothini zombili, ikhanda elincane elixhunywe ku-piston, ikhanda elikhulu elixhunywe ku-crankshaft.
5. Ukuthwala induku yokuxhuma: ingxenye yokugcoba efakwe ekhanda elikhulu lenduku yokuxhuma.
6. Ibhawodi yenduku yokuxhuma: ibhawudi elilungisa isiphetho esikhulu senduku yokuxhuma ku-crankshaft.
I-piston ring iyingxenye eyinhloko ngaphakathi kwenjini kaphethiloli, yona nesilinda, i-piston, i-cylinder wall ndawonye ukuze kuqedelwe uphawu lwegesi yamafutha. Izinjini zezimoto ezisetshenziswa kakhulu zinezinhlobo ezimbili zezinjini zikadizili nekaphethiloli, ngenxa yokusebenza kwazo okuhlukile kukaphethiloli, ukusetshenziswa kwezindandatho zepiston akufani, izindandatho zakuqala zepiston zakhiwa ngokuphonswa, kodwa ngokuqhubeka kobuchwepheshe, insimbi enamandla amakhulu. Amasongo e-piston azalwa, futhi ngomsebenzi wenjini, izidingo zemvelo ziyaqhubeka nokuba ngcono, izinhlobonhlobo zezicelo ezithuthukisiwe zokwelashwa kwendawo, njengokufafaza okushisayo, i-electroplating, i-chrome plating, njll. I-nitriding yegesi, ukufakwa ngokomzimba, ukumbozwa kwendawo, ukwelashwa kwe-zinc manganese phosphating, njll., kuthuthukisa kakhulu umsebenzi we-piston ring.
Iphinikhodi ye-piston isetshenziselwa ukuxhuma i-piston kwintonga yokuxhuma futhi idlulise amandla ku-piston kwintonga yokuxhuma noma ngokuphambene nalokho.
Iphinikhodi ye-piston ingaphansi komthwalo omkhulu womthelela wezikhathi ezithile ngaphansi kwezimo eziphakeme zokushisa, futhi ngenxa yokuthi i-Angle yokujika yephinikhodi yephinikhodi ayinkulu, kunzima ukwenza ifilimu yokugcoba, ngakho-ke isimo sokuthambisa sibi. Ngenxa yalesi sizathu, iphinikhodi ye-piston kufanele ibe nokuqina okwanele, amandla nokumelana nokugqoka. Isisindo sincane ngangokunokwenzeka, futhi iphini kanye nembobo yokukhonkwane kufanele kube nezikhala ezifanele ezihambisanayo kanye nekhwalithi enhle yendawo. Ngokuvamile, ukuqina kwephinikhodi ye-piston kubaluleke kakhulu, uma iphinikhodi ye-piston igoba i-deformation, ingase ibangele umonakalo esihlalweni sephinikhodi.
Ngamafuphi, isimo sokusebenza sephinikhodi ye-piston ukuthi isilinganiso sokucindezela sikhulu, ifilimu yamafutha ayikwazi ukwakhiwa, futhi ukuguqulwa akuhambisani. Ngakho-ke, ukuklama kwayo kudinga amandla aphezulu ngokwanele emishini kanye nokumelana nokugqoka, kodwa futhi amandla aphezulu okukhathala.
Umzimba wenduku yokuxhuma wakhiwe izingxenye ezintathu, futhi ingxenye exhunywe nephinikhodi ye-piston ibizwa ngokuthi induku yokuxhuma ikhanda elincane; Ingxenye exhunywe ne-crankshaft ibizwa ngokuthi inhloko enkulu yenduku yokuxhuma, futhi ingxenye exhuma ikhanda elincane nekhanda elikhulu ibizwa ngokuthi umzimba wenduku yokuxhuma.
Ukuze kuncishiswe ukuguga phakathi kwekhanda elincane nephinikhodi, i-bronze bushing enezindonga ezincane icindezelwa emgodini omncane wekhanda. Gcoba noma umshini wokugaya ungene emakhanda amancane nasezihlahleni ukuze uvumele ukuchaphaza kwamafutha kungene endaweni yokukhwelana yephinikhodi ye-bushing-piston yokugcoba.
Umzimba wenduku yokuxhuma uyinduku ende, futhi amandla emsebenzini nawo makhulu, ukuze avimbele ukuguqulwa kwawo okugoba, umzimba wenduku kufanele ube nokuqina okwanele. Ngenxa yalesi sizathu, umzimba wenduku yokuxhuma yenjini yemoto ngokuvamile wamukela isigaba se-shape I, esinganciphisa ubukhulu ngaphansi kwesimo sokuthi ukuqina namandla anele, futhi injini yamandla aphezulu inesigaba esimise okwe-H. Ezinye izinjini zisebenzisa induku yokuxhuma ipiston yokupholisa yamafutha omjovo omncane wekhanda, okumele ibhojwe ngembobo yobude emzimbeni wenduku. Ukuze ugweme ukugxilwa kokucindezeleka, umzimba wenduku yokuxhuma, ikhanda elincane nekhanda elikhulu lixhunywe uguquko olubushelelezi oluyindilinga.
Ukuze kuncishiswe ukudlidliza kwenjini, umehluko wekhwalithi wenduku yokuxhuma isilinda kufanele ukhawulelwe kububanzi obuncane, ekuhlanganiseni kwemboni yenjini, ngokuvamile ngamagremu njengeyunithi yokulinganisa ngokwesisindo esikhulu nesincane. induku yokuxhuma, injini efanayo yokukhetha iqembu elifanayo lenduku yokuxhuma.
Enjinini yohlobo lwe-V, amasilinda ahambisanayo kumakholomu angakwesokunxele nangakwesokudla abelana ngephinikhodi, futhi induku yokuxhuma inezinhlobo ezintathu: induku yokuxhuma ehambisanayo, induku yokuxhuma imfoloko kanye nenduku yokuxhuma eyinhloko neyisizayo.
Amathayela afakwe kubakaki abangaguquki be-crankshaft nesilinda block futhi adlala indima yokuthwala nokugcoba ngokuvamile abizwa ngokuthi ama-crankshaft bearing pads.
Ukuzala kwe-Crankshaft ngokuvamile kuhlukaniswe ngezinhlobo ezimbili: ukuzala (Umfanekiso 1) kanye ne-flanged bear (Umfanekiso 2). I-flanged bear bushing ayikwazi ukusekela kuphela futhi igcobe i-crankshaft, kodwa futhi idlale indima yokuma kwe-axial ye-crankshaft (kungaba nendawo eyodwa kuphela ku-crankshaft ukusetha idivayisi yokumisa i-axial).
Uma sisebenzisa ama-bolts enduku yokuxhuma, sizothola ukuthi kunezinkinga eziningi zokuxhuma izinduku zenduku, kuzoba nezinkinga zokubukeka, izinkinga zobude bokubekezelelana, izinkinga zokuphuka, izinkinga zentambo yezinyo, izinkinga ezitholakala ngesikhathi sokufakwa, njalonjalo.
Indlela elula ukuhlola ibhowudi yenduku yokuxhuma, thola ukuthi inkinga ilele kuphi bese uyishintsha. Ukuhlolwa kwebholithi yenduku yokuxhuma kudinga indlela. Ibhowudi yenduku yokuxhuma iyibhawodi ebalulekile exhuma isihlalo sokuthwala somkhawulo omkhulu wenduku yokuxhuma kanye nesembozo sokuthwala. Ibhawodi yenduku yokuxhuma ingaphansi kwesenzo samandla okulayisha ngaphambili ngesikhathi sokuhlanganiswa, futhi ibholidi yenduku yokuxhuma nayo ingaphansi kwesenzo sokuphindaphinda amandla e-inetia lapho injini yedizili enemivimbo emine isebenza. Ububanzi bebhowudi yenduku yokuxhuma buncane ngoba bukhawulwa ububanzi bephinikhodi ye-crank kanye nosayizi wompheme ongaphandle wesiphetho esikhulu senduku yokuxhuma.
Ibhawodi ehlanganisa isembozo senduku ehlukanisayo ehlukanisayo ekugcineni okukhulu kwenduku yokuxhuma. Epheyani ngalinye lamabheringi, amabholothi enduku yokuxhuma amabili noma amane ngokuvamile asetshenziselwa ukuwavikela. Uhlobo lwebhawudi luyahlukahluka. Ikhanda livamise ukwenziwa ngomshini ngendiza yokuma noma ibhulokhi eliyiconvex ukuze lifakwe futhi lishumekwe ngendawo yokusekela ethwele ukuze kuvinjwe ibhawodi yenduku yokuxhuma ukuthi ingazungezi lapho iqinisa inathi. Ububanzi bomzimba wenduku ye-bolt endaweni ngayinye yesigaba sokuthwala bukhulu, ukuze bubekwe ngembobo ye-bolt ngesikhathi sokuhlanganiswa; Ububanzi bayo yonke ingxenye yomzimba wenduku yebhawodi buncane kunobubanzi bembobo yebhawodi, futhi ubude bude, ukuze umthwalo wengxenye yentambo ungancishiswa lapho ukugoba kanye nomthwalo womthelela uthwalwa. Ingxenye yochungechunge ngokuvamile ithatha intambo enhle ngokunemba okuphezulu.
Ukuze uvimbele ukuxhuma okunentambo ekuzixegiseni, ibhowudi yenduku yokuxhuma inesisetshenziswa esinqanda ukuxegisa unomphela, ngokuvamile okuyiphinikhodi ye-cotter, iwasha evimbela ukuxega kanye ne-copper plating endaweni yochungechunge. Amabhawodi enduku yokuxhuma ngokuvamile athwala imithwalo eshintshanayo, okulula ukubangela ukulimala kokukhathala nokuphuka, okuzodala imiphumela emibi kakhulu. Ngakho-ke, kuvame ukwenziwa ngensimbi ye-alloy yekhwalithi ephezulu noma i-carbon steel yekhwalithi ephezulu, nangemva kokwelashwa kokushisa kokushisa. Ekuphatheni, kufanele kuqashelwe ukuhlola ukuqina kwayo ukuvimbela ukuxega; I-disassembly evamile ihlole ukuqhekeka nokunwebeka ngokweqile, njll., kufanele kushintshwe ngesikhathi uma kunesidingo. Lapho ufaka, kuyadingeka ukuwela futhi kancane kancane uqinise ngokuvumelana namandla anqunyiwe angaphambi kokuqinisa, angeke abe mkhulu kakhulu noma abe mncane kakhulu, ukuze agweme izingozi ezifana nokuphulwa kwebholiti yenduku emsebenzini.
