Ubuchwepheshe bokunciphisa ukungqubuzana kwezingxenye zenjini yemoto

Njengesilinganiso sokunciphisa ukungqubuzana phakathi kwezingxenye zenjini yezimoto, kungahlukaniswa cishe kube yizinhlobo ezintathu ezilandelayo.

Enye ukunciphisa indawo yokuxhumana yangempela phakathi kwezinto;

Okwesibili ukwenza ukucindezeleka okuphansi kwe-shear phakathi kwezingxenye;

Okwesithathu ukunciphisa umthwalo wokufaka phakathi kwezinto.

Ukunciphisa ubukhulu bendawo yezingxenye kusiza ukunciphisa ukuxhumana kwangempela phakathi kwezingxenye. Ngesisekelo sokungashintshi ubukhali bokuqala bendawo, ingaphezulu lezinto zokumatanisa lingahlehliswa ngokuslayida, okungaqhubeka nokunciphisa amandla wokuphambana.

Njengamanje, iningi lama-bores cylinder bores akhiwa ngokusakaza ama-bushings enziwe nge-grey cast iron ebangeni le-aluminium alloy cylinder block. Ukuqhutshwa kokushisa kwensimbi yensimbi (50W / (m · k)) kungaphansi kune-aluminium (100W / (m · k)), futhi ubukhulu bensimbi yensimbi bungamamilimitha amaningana. Muva nje, ukuze kuthuthukiswe ukushabalalisa ukushisa egumbini lomlilo, kusetshenziswe imikhono yensimbi yensimbi esikhundleni sezinsimbi zesilinda, bese kufuthwa insimbi. Lokhu kungathuthukisa ukubekwa kwesibonisi futhi kunciphise udonga lweshubhu, okuthuthukisa kakhulu ukudluliswa kokushisa nokudluliswa kokushisa kule ngxenye. Ukudluliswa kokushisa.

Ngaphezu kwalokho, njengesimo esihlukile ekufuthweni okushisayo, kufakwa izinga elithile lama-void kwifilimu, futhi ama-void adalulwa kungqimba olungaphezulu, olungathuthukisa ukugcinwa kukawoyela kobuso besilinda.

Njengoba kungadingeki ukusebenzisa i-mesh honing yenjini evamile yenjini eyisilinda ukuqinisekisa ukugcinwa kukawoyela, ingaphezulu le-cylinder bore lingasetshenziswa. Ngaphezu kwezinzuzo ezibalwe ngenhla zezici ezinhle zokudlulisa ukushisa, futhi inganciphisa ngempumelelo ukungqubuzana kusuka emngceleni kuya endaweni ehlanganisiwe yokuthambisa.

　　 Ngokuphathelene nokuxhumana okukhona phakathi kokungqubuzana kobuso bezingxenye, lonke ungqimba lobuso kufaka phakathi okuvezwayo kusetshenziswa njengezinto zokucindezela ukushefa okuphansi. Njengendlela yokwehlisa ukuqina nokunciphisa ukungqubuzana kukodwa, kungasetshenziswa izinto zokugcoba eziqinile.

Ikakhulu, lapho ingcindezi yendawo ingekho phezulu kangako, okusetshenziswa okubizwa ngokuthi ukuthambisa okuthambile kungasetshenziswa, okungukuthi, i-granular molybdenum disulfide (MoS2) noma i-graphite, kanye ne-tetrafluoroethylene njenge-lubricant eqinile ihlakazeka ku-polyamide resin (PAI) phakathi, noma ukumbozwa okutholwe ngokukhanyisa ngqo izinhlayiya ze-MoS2 ngokuqhathanisa nomsebenzi wokusebenza ngesivinini esikhulu. Lolu hlobo lokumboza lungasetshenziswa kungqimba olungaphezulu lwenduku ye-piston ne-crankshaft equkethe ingxubevange enendawo enkulu yokuxhumana ezingxenyeni zenjini.

Ngakolunye uhlangothi, ezingxenyeni ezinengcindezi ephezulu yendawo, sithuthukise ukugcotshwa kwe-DLC okunenani elifanayo lokushayisana eliphansi njenge-lubricant eqinile lapho kunzima futhi kungathanjiswanga, ukuze umphumela ofanayo utholakale ngaphansi kokuthambisa. Ukumboza.

Lo mbhalo uzokwethula ifilimu ye-DLC engenayo i-hydrogen (ifilimu engenayo i-hydrogen DLC) nefilimu ye-DLC equkethe iSi (Si-DLC). Lokhu okubili kwehluke kakhulu kokwedlule mayelana nokwelashwa komhlaba nokuklanywa kokucabanga ngokuthi ukumboza uqobo akunazici ezihlukile, futhi inhlanganisela kawoyela wokuthambisa noma umswakama okuwoyela wokuthambisa unganciphisa kakhulu ukungqubuzana.

　　Ukuze kuncishiswe ukungqubuzana phakathi kwendandatho ye-piston ne-cylinder bore, eminyakeni yamuva nje, ifilimu ye-CrN isetshenziselwe ukufaka esikhundleni sobuchwepheshe obudlule be-Cr plating noma i-nitriding technology. Ubukhulu befilimu ka-Cr-plated bucishe bube yi-100, kanti ukushuba kwefilimu ye-CrN enokuqina okuhle kokugqoka kungama-25 kuphela, okunganciphisa ububanzi bokuphambuka kobukhulu befilimu. Ngenxa yalokhu, ngaphandle kokushintsha umkhawulo ongezansi wokungezwani kwepiston ring, futhi kuphela ukubeka inani eliphakathi ukuthi lincane, ukungqubuzana phakathi kwendandatho ye-piston ne-cylinder bore kungancishiswa.

Ngaphezu kwalokho, njengoba inani lokugqokwa kwefilimu ye-CrN lincane, ukuvinjelwa kokuqala kwendawo yangaphandle yeringini ye-piston kungagcinwa, futhi uhla lokuxhumana olwengeziwe ngenxa yokugqoka lungacindezelwa, okusiza futhi ukunciphisa ukungqubuzana.

Sicela ugcine umthombo nekheli lale ndatshana ukuze uphinde uprintwe: Ubuchwepheshe bokunciphisa ukungqubuzana kwezingxenye zenjini yemoto

UMinghe Inkampani yeDie Casting anikezelwe ekukhiqizeni nasekuhlinzekeni ikhwalithi nokusebenza okuphezulu Izingxenye Zokulingisa (izingxenye zensimbi zensimbi zokufa zisebenza ikakhulukazi zibandakanya I-Thin-Wall Die Casting,I-Hot Chamber Die Casting,Cold Chamber die Casting), Insizakalo Eyindilinga (Insiza Yokulingisa,ICnc Machining,Ukwenza Okubandayo, Surface Treatment) .Noma ikuphi ukusakazwa kwe-Aluminium die, i-magnesium noma i-Zamak / zinc die casting nezinye izidingo zokuphosa zamukelekile ukuxhumana nathi.

Ngaphansi kokulawulwa kwe-ISO9001 ne-TS 16949, Zonke izinqubo zenziwa ngamakhulu emishini esezingeni eliphakeme yokufa, imishini ye-5-axis, nezinye izikhungo, ezisukela kuma-blasters kuya kumishini yokuwasha ye-Ultra Sonic.Minghe akagcinanga ngemishini esezingeni eliphezulu kepha futhi unobuchwepheshe iqembu lonjiniyela abanolwazi, ama-opharetha nabahloli ukwenza ukwakheka kwekhasimende kugcwaliseke.

Umenzi wenkontileka yokufa kwabasikiwe. Amandla afaka izingxenye ezibandayo ze-aluminium die casting ezivela ku-0.15 lbs. kuye ku-6 lbs., Ukusetha ushintsho olusheshayo, nemishini. Izinsizakalo ezingezwe ngenani zifaka phakathi ukupholisha, ukudlidliza, ukuphazamisa, ukuqhumisa ngokudubula, ukupenda, ukuhlobisa, ukumboza, ukuhlangana nokusetshenziswa kwamathuluzi. Izinto zokusebenza ezisetshenzisiwe zifaka ama-alloys afana no-360, 380, 383, no-413.

I-Zinc die casting design usizo / izinsizakalo zobunjiniyela ezihambisanayo. Umenzi wangokwezifiso we-precision zinc die castings. Ukusakazwa okuncane, ukukhishwa kwengcindezi ephezulu, ukusikeka kwesikhunta esiningi, ukujikijelwa kwesikhunta okuvamile, ukufefa kwamayunithi kanye nokuzimela okuzimele kanye nokuvalwa okuvaliwe komgodi kungenziwa. Ama-Castings angenziwa ngobude nobubanzi obufinyelela ku-24 in. Ku +/- 0.0005 in. Ukubekezelelana.  

I-ISO 9001: Umkhiqizi oqinisekisiwe ka-2015 we-die cast magnesium, Amandla afaka i-high-pressure magnesium die casting up to 200 ton chamber hot & 3000 ton cold chamber, designing designing, polishing, molding, machining, powder & liquid paint, QA full with CMM amakhono , inhlangano, ukupakisha nokulethwa.

Kuqinisekiswe i-ITAF16949. Insiza Eyengeziwe Yokulingisa Faka ukukhipha utshalomali,ukuphonsa kwesihlabathi,Ukuphonswa kwamandla, Lost Foam Ekubunjweni,I-Centrifugal Casting,Ukuphoswa Kokuqothula,Permanent Isikhunta Ukulingisa, Amakhono afaka i-EDI, usizo lobunjiniyela, ukumodeliswa okuqinile nokucutshungulwa kwesibili.

Izimboni Zokulingisa Izingxenye Zamacala Ezifundo Zezimoto: Izimoto, Amabhayisikili, Izindiza, Izinsimbi Zomculo, I-Watercraft, Amadivayisi we-Optical, Izinzwa, Amamodeli, Amadivayisi we-elekthronikhi, Ukuvaleka, Amawashi, Imishini, Izinjini, Ifenisha, Ubucwebe, AmaJig, Telecom, Ukukhanyisa, Amadivayisi Wezokwelapha, amadivayisi wezithombe, Amarobhothi, okubaziwe, okokusebenza komsindo, okwezemidlalo, i-Tooling, Amathoyizi nokuningi. 

Yini esingakusiza ukuthi uyenze ngokulandelayo?
