Iyini i-piston assembly?
Ukuhlanganiswa kwepiston kuyingxenye ebalulekile yenjini yemoto, eyakhiwa kakhulu yizingxenye eziyisithupha ezilandelayo:
1. I-Piston: Iyingxenye yegumbi lokushisa futhi ifakwe imigoqo eminingana yokufaka indandatho ye-piston.
2. Indandatho yepiston: Ifakwa ku-piston ukuze ivalwe, ngokuvamile yakhiwe ngendandatho yegesi kanye nendandatho kawoyela.
3. Iphinikhodi yepiston: Ukuxhuma iphinikhodi kanye nekhanda elincane lenduku yokuxhuma yepiston, kunezindlela ezimbili zokuntanta okugcwele kanye nokuntanta okuyingxenye.
4. Induku yokuxhuma yepiston: induku yokuxhuma yepiston kanye ne-crankshaft, ihlukaniswe yaba ikhanda elikhulu nekhanda elincane ezinhlangothini zombili, ikhanda elincane elixhunywe kwi-piston, ikhanda elikhulu elixhunywe kwi-crankshaft.
5. Ukuthwala induku yokuxhuma: ingxenye yokugcoba efakwe ekhanda elikhulu lenduku yokuxhuma.
6. Ibhawodi yenduku yokuxhuma: ibhawodi elungisa ingxenye enkulu yenduku yokuxhuma ku-crankshaft.
Indandatho yepiston iyisici esiyinhloko ngaphakathi kwenjini kaphethiloli, yona kanye nesilinda, i-piston, nodonga lwesilinda ndawonye ukuze kuqedwe uphawu lwegesi kaphethiloli. Izinjini zezimoto ezisetshenziswa kakhulu zinezinhlobo ezimbili zezinjini zedizili nephethiloli, ngenxa yokusebenza kwazo okuhlukile kukaphethiloli, ukusetshenziswa kwezindandatho zepiston akufani, izindandatho zepiston zokuqala zakhiwa ngokukhipha, kodwa ngentuthuko yobuchwepheshe, izindandatho zepiston ezinamandla aphezulu zazalwa, futhi ngomsebenzi wenjini, izidingo zemvelo ziyaqhubeka nokuthuthuka, izinhlelo ezahlukene zokwelapha ubuso obuphambili, njengokufutha ngokushisa, ukufakelwa kwe-electroplating, ukufakwa kwe-chrome, njll. I-gas nitriding, ukufakwa ngokomzimba, ukumbozwa kobuso, ukwelashwa kwe-zinc manganese phosphating, njll., kuthuthukisa kakhulu umsebenzi wendandatho yepiston.
Iphini le-piston lisetshenziselwa ukuxhuma i-piston endukwini yokuxhuma bese lidlulisela amandla e-piston endukwini yokuxhuma noma okuphambene nalokho.
Iphini le-piston libhekene nomthwalo omkhulu wokuthinta ngezikhathi ezithile ngaphansi kwezimo zokushisa okuphezulu, futhi ngenxa yokuthi i-engela yokujika yephini le-piston emgodini wephini ayinkulu, kunzima ukwakha ifilimu yokugcoba, ngakho-ke isimo sokugcoba asisihle. Ngenxa yalesi sizathu, iphini le-piston kumele libe nokuqina okwanele, amandla kanye nokumelana nokuguguleka. Ubunzima buncane ngangokunokwenzeka, futhi iphini kanye nomgodi wephini kufanele kube nezikhala ezifanele zokufanisa kanye nekhwalithi enhle yobuso. Ngokuvamile, ukuqina kwephini le-piston kubaluleke kakhulu, uma ukuguqulwa kokugoba kwephini le-piston, kungabangela umonakalo esihlalweni sephini le-piston.
Ngamafuphi, isimo sokusebenza sephini le-piston ukuthi isilinganiso sokucindezela sikhulu, ifilimu kawoyela ayikwazi ukwakheka, futhi ukuguqulwa kwayo akuhlangani. Ngakho-ke, ukwakheka kwayo kudinga amandla aphezulu okusebenza kanye nokumelana nokuguguleka, kodwa futhi namandla aphezulu okukhathala.
Umzimba wenduku yokuxhuma wakhiwe izingxenye ezintathu, kanti ingxenye exhunywe nephini le-piston ibizwa ngokuthi induku yokuxhuma inhloko encane; Ingxenye exhunywe ne-crankshaft ibizwa ngokuthi inhloko enkulu yenduku yokuxhuma, kanti ingxenye exhumanisa ikhanda elincane nekhanda elikhulu ibizwa ngokuthi umzimba wenduku yokuxhuma.
Ukuze kuncishiswe ukuguguleka phakathi kwekhanda elincane nephini le-piston, i-bronze bushing enodonga oluncane icindezelwa emgodini omncane wekhanda. I-Drill noma i-mill grooves ingena emakhanda amancane nasezihlahleni ukuze kuvunyelwe ukuchaphaza kwamafutha ukuthi kungene ebusweni bokuhlangana kwephini le-bushing-piston eligcobayo.
Umzimba wenduku yokuxhuma uyinduku ende, futhi amandla asebenzayo nawo makhulu, ukuze kuvinjelwe ukuguquguquka kwayo kokugoba, umzimba wenduku kumele ube nokuqina okwanele. Ngenxa yalesi sizathu, umzimba wenduku yokuxhuma wenjini yemoto uvame ukusebenzisa isigaba sokuma I, esinganciphisa ubunzima ngaphansi kwesimo sokuthi ukuqina namandla kwanele, kanti injini enamandla aphezulu inesigaba esimise okwe-H. Ezinye izinjini zisebenzisa i-piston yokupholisa uwoyela wenduku yokuxhuma encane, okumele ibhobozwe ngembobo ende emzimbeni wenduku. Ukuze kugwenywe ukugxila ekucindezelekeni, umzimba wenduku yokuxhuma, ikhanda elincane kanye nekhanda elikhulu kuxhunywe ngoshintsho olukhulu olubushelelezi oluyindilinga.
Ukuze kuncishiswe ukudlidliza kwenjini, umehluko wekhwalithi yenduku yokuxhuma yesilinda kumele ulinganiselwe ebangeni elincane, ekuhlanganisweni kwefektri yenjini, ngokuvamile ngamagremu njengeyunithi yokulinganisa ngokuya ngesisindo esikhulu nesincane senduku yokuxhuma, injini efanayo ukukhetha iqembu elifanayo lenduku yokuxhuma.
Enjinini yohlobo lwe-V, amasilinda ahambisanayo kumakholomu angakwesobunxele nakwesokudla abelana ngephini le-crank, kanti induku yokuxhuma inezinhlobo ezintathu: induku yokuxhuma ehambisanayo, induku yokuxhuma yefoloko kanye nenduku yokuxhuma eyinhloko nesizayo.
Amathayili afakwe kuma-bracket aqinile e-crankshaft kanye ne-cylinder block futhi adlala indima yokuthwala kanye nokugcoba ngokuvamile abizwa ngokuthi ama-crankshaft bearing pads.
Ukuthwala kwe-crankshaft ngokuvamile kuhlukaniswe izinhlobo ezimbili: ukuthwala (Isithombe 1) kanye nokuthwala kwe-flanged (Isithombe 2). I-Flanged bearing bushing ayikwazi ukusekela nokugcoba i-crankshaft kuphela, kodwa futhi idlala indima yokubeka i-axial ye-crankshaft (kungaba nendawo eyodwa kuphela ku-crankshaft yokusetha idivayisi yokubeka i-axial).
Uma sisebenzisa amabhawodi enduku yokuxhuma, sizothola ukuthi kunezinkinga eziningi ngamabhawodi enduku yokuxhuma, kuzoba nezinkinga zokubukeka, izinkinga zobude bokubekezelelana, izinkinga zokuphuka, izinkinga zentambo yamazinyo, izinkinga ezitholakala ngesikhathi sokufakwa, njalo njalo.
Indlela elula ukuhlola i-connecting rod bolt, uthole ukuthi inkinga ikuphi bese uyishintsha. Ukuhlolwa kwe-connecting rod bolt kudinga indlela. I-connecting rod bolt iyi-bolt ebalulekile exhumanisa isihlalo sokuthwala se-big end ye-connecting rod kanye nesembozo se-bearing. I-connecting rod bolt ifakwa esenzweni samandla okulayisha kusengaphambili ngesikhathi sokuhlanganiswa, kanti i-connecting rod bolt nayo ifakwa esenzweni samandla okubuyisela lapho injini ye-diesel ene-stroke ezine isebenza. Ububanzi be-connecting rod bolt buncane ngoba bunqunyelwe ububanzi be-crank pin kanye nosayizi we-veranda yangaphandle ye-big end ye-connecting rod.
Ibhawodi elixhumanisa isembozo senduku yokuxhuma esihlukanisiwe nengxenye enkulu yenduku yokuxhuma. Kuma-bearings amabili noma amane, ngokuvamile kusetshenziswa amabhawodi amabili noma amane okuxhumanisa ukuze awaqinise. Uhlobo lwebhawodi luyahlukahluka. Ikhanda livame ukushintshwa ngendiza yokuma noma ibhulokhi eliyindilinga ukuze lifakwe futhi lifakwe endaweni yokusekela amabhereyi ukuvimbela ibholodi lenduku yokuxhuma ukuthi lingajikelezi lapho kuqinisa inathi. Ububanzi bomzimba wenduku yebhawodi endaweni ngayinye yengxenye yebhereyi bukhulu, ukuze bubekwe nembobo yebhawodi ngesikhathi sokuhlanganiswa; Ububanzi bengxenye esele yomzimba wenduku yebhawodi buncane kunobubanzi bembobo yebhawodi, futhi ubude bude, ukuze umthwalo wengxenye yentambo ungancishiswa lapho umthwalo wokugoba kanye nowokuthinteka uthwalwa. Ingxenye yentambo ivame ukusebenzisa intambo encane ngokunemba okuphezulu.
Ukuze kuvinjelwe uxhumano olunezintambo ukuthi lungazikhululeki, ibholthi yenduku exhumanisayo inedivayisi ehlala njalo yokulwa nokuxegisa, ngokuvamile eyi-cotter pin, i-washer yokulwa nokuxegisa kanye ne-copper plating ebusweni bentambo. Amabholthi enduku axhumanisayo avame ukuthwala imithwalo eshintshanayo, okulula ukubangela umonakalo nokuphuka kokukhathala, okuzobangela imiphumela emibi kakhulu. Ngakho-ke, ivame ukwenziwa ngensimbi ye-alloy esezingeni eliphezulu noma insimbi yekhabhoni esezingeni eliphezulu, futhi ngemva kokushisa okushisayo. Ekuphatheni, kufanele kuqashelwe ukuhlola ukuqina kwayo ukuze kuvinjelwe ukuxegisa; Ukuyihlukanisa njalo kufanele kuhlolwe ukuthi ayinamifantu kanye nobude obukhulu, njll., kufanele kushintshwe ngesikhathi uma kudingeka. Lapho uyifaka, kuyadingeka ukuwela nokuqinisa kancane kancane ngokuya ngamandla anqunyiwe okuqinisa ngaphambi kokuqina, angeke abe makhulu kakhulu noma abe mancane kakhulu, ukuze kugwenywe izingozi ezifana nokuphuka kwebholthi yenduku emsebenzini.
