Izinjini ze-Enjini Crankshaft Flkwheel Group
Okokuqala, crankshaft
I-Crankshaft ingenye yezingxenye ezibaluleke kakhulu zenjini, umsebenzi wayo ukumelana nengcindezi yegesi kusuka ku-porque exhumanisa i-torque kanye namanye ama-crankshaft, ama-crankshaft, amaphampu wamanzi, amaphampu we-bach shaft, njll.)
I-Crankshaft Flyheel Group: 1- pulley; 2- crankshaft isikhathi izinyo ibhonga ibhande; 3- I-Crankshaft I-Sprock; 4- crankshaft; 5- I-Crankshaft Main Bearing (Phezulu); 6- I-FlyWheel; 7- I-Speed Sensor Signal Generator; 8, 11- throst pad; 9- CRANKSHAFT EXIENCH (Phansi); Isembozo esiyinhloko sokuthwala.
Lapho i-crankshaft isebenza, kufanele ikwazi ukumelana nezinguquko zegesi ngezikhathi ezithile, iphinde ibuyise amandla amakhulu kanye ne-centrifugal Force, okulula ukugoba nokuqina kwe-crankshaft. I-crankshaft ivame ukwenziwa ngensimbi ephakathi kwekhabhoni, futhi ingaphezulu lezincwadi zelashwa ngokugqama okukhulu okuqediwe noma i-nitriding. I-Shanghai Santana Injini Crankshaft yenziwa ngekhwalithi ephezulu ye-carbon carbon die eqolayo. Izinjini ze-Audi JW kanye ne-Yuchai yc6105qc zenziwe ngentengo ephansi, amandla aphezulu emhlaba angenasisekelo ensimbi yensimbi enomelana kahle.
1. Ukwakheka kwe-crankshaft
I-crankshaft ngokuvamile yakhiwa ukuphela kwangaphambili, intamo enkulu ye-shaft, i-crank, i-counterweight, iphephabhuku lenduna elixhumayo nendawo esemuva. I-crank yakhiwa nge-Connecting Ronnel Journal kanye namaphephabhuku aphambili wesobunxele nakwesokudla. Inani le-crank le-crankshaft lincike enanini kanye nokuhlelwa kwama-cylinders. I-crankshaft yenjini eyodwa yesilinda ine-crank eyodwa kuphela; Inani le-crank le-crankshaft lenjini engaphakathi lilingana nenani lamasilinda; Inani lama-cranks ku-crankshaft wenjini ye-V lilingana nengxenye yesilinda. Umgodi ongaphambili we-crankshaft uhlome nge-pulley, igiya lesikhathi, njll., Elisetshenziselwa ukushayela iphampu yamanzi kanye ne-valve mechanism. Intamo ye-spindle ye-crankshaft ifakwa esihlalweni esikhulu sokuthwala somzimba wesilinda futhi isetshenziselwa ukusekela i-crankshaft. I-Connecting Ronner Journal isetshenziselwa ukufaka induku yokuxhuma, futhi i-crank ixhumanisa iphephabhuku elikhulu le-main shage nge-Connecting Rebormu ye-ROD. Ukuze ulinganise amandla we-centrifugal lapho i-crankshaft ijikeleza, ibhalansi yebhalansi inikezwe ku-crankshaft. I-Falling Flange ihlinzekwe ekugcineni kwe-crankshaft yokuxhuma i-flywheel ku-crankshaft ngama-bolts. Ukugcoba iphephabhuku le-Connecting Rood, ukugcoba kwendima kudonswa kusuka ku-Main Shaft Journal kwi-Connecting Rebormu ye-ROD. I-CrankShaft ehlanganisiwe ilula ngesakhiwo, ukukhanya ngesisindo nokusebenza okuthembekile ekusebenzeni, futhi ngokuvamile yamukela ama-turner, asetshenziswa kabanzi ezinjini eziphakathi nendawo ezincane.
2. Isimiso sesakhiwo se-crank
Ukwakheka kwe-crankshaft kanye nesikhundla esihlobene ne-crank ngayinye kuncike kakhulu kwinani lama-cylinders, ukuhlelwa kwamasilinda kanye nokusebenza kwe-cylinder ngayinye. Lapho kuhlela ukulandelana komsebenzi wenjini, imithetho elandelayo kufanele ilandelwe ngangokunokwenzeka:
Yenza amasilinda amabili omsebenzi oqhubekayo kude ngangokunokwenzeka ukunciphisa umthwalo wokuthwala okukhulu, futhi uvikele ukwenzeka kwama-valve ama-valve amabili axhunyiwe ngasikhathi sinye ngesikhathi sokudla, futhi into "yokubamba umoya" ithinta ukusebenza kahle kwenjini.
(1) I-angle yokusebenza yesilinda ngasinye kufanele ilingane nokwenza lula ukusebenza okubushelelezi kwenjini. Ngaphakathi kwe-crankshaft angle lapho injini iqeda khona umjikelezo osebenzayo, isilinda ngasinye kufanele sisebenze kanye. Kwinjini enamakamelo amane ngenombolo yesilinda i, i-angle yokusebenza ye-Work I-720 ° / I. Okungukuthi, njalo ngo-720 ° / i-i crankshaft kufanele kube nesilinda somsebenzi ukuze aqinisekise ukuthi injini igijima kahle.
(2) Uma kuyinjini yohlobo lwe-V, amakholomu wesobunxele nakwesokudla wama-cylinders kufanele aguqule umsebenzi.
3. Ilungiselelo elijwayelekile le-multi-cylinder injini yokuhleleka nokuhleleka okusebenzayo
Ukuhlelwa kwe-crankshaft kanye ne-crank yenjini yokuhlanza intambo emine. I-angle yesikhathi sokusebenza se-in-line-cylinder injini engu-70 ° / 4 = 180 °, i-crank yokulandelana kokulandelana (noma ukulandelana kokulandelana (noma ukulandelana kokulandelana) yi-1-3-4 noma 1-2-4-2. Idivaysi yokusebenza esetshenziswayo esetshenziswayo isetshenziswa kakhulu ine-pad eyodwa ye-semi-isiyingi se-semi-isiyingi esine-anti-friction metal ungqimba, i-crankshaft main ethwele nge-flating and round tust ring inezindlela ezintathu. I-throutt pad ishidi lensimbi le-semi-ring eline-anti-chark alloy ungqimba ngaphandle, okufakwe ku-groove womzimba noma isembozo esikhulu sokuthwala. Ukuze uvikele ukujikeleza kwepakethe le-thrust, i-thrust pad inenqwaba ebambelele e-groove. Amanye ama-thrust pads asebenzisa izingcezu ezi-4 ukwakha imikhawulo emibili eyindilinga emibili, futhi ezinye zisebenzisa izingcezu ezi-2 zemikhawulo. Uhlangothi olunensimbi elwa ne-anti-arry kufanele lubhekane ne-crankshaft.
UZhuo Meng Shanghai Auto Co, Ltd uzibophezele ekuthengiseni izingxenye ze-MG & Mauxs auto wamukelekile ukuthenga.
