Ngokocwaningo lwemakethe lwe-3D Science Valley, amabhizinisi okuphrinta e-ceramic 3D agxile ocwaningweni nasekuthuthukisweni kwezinhlelo zokuphrinta ze-ceramic 3D zezinga lokukhiqiza, kuyilapho ubuchwepheshe bokuphrinta be-3D obunezindleko eziphansi nokunemba okuphezulu kungena emakethe. Umkhuba wakamuva wokuthuthuka wokukhiqiza izithasiselo ze-ceramic ukungena emkhakheni wokukhiqiza imikhiqizo enenani eliphakeme kakhulu, okuhlanganisa i-ceramic 5G antenna, i-ceramic collimator, izakhi zenuzi, ama-ceramic bearings...
Muva nje, i-China Mechanical Engineering Society lonke uchungechunge olune-ceramic lwamazinga amathathu eqembu akhishwe ngokusemthethweni.

Ikholomu kaGu ethi "Umlando, Ukuthuthukiswa kanye Nekusasa Lezinto Zobumba Zokukhiqiza Ezingeziwe" ixoxa ngezinhlobo eziyisikhombisa zobuchwepheshe bokuphrinta be-3D ukwenza izingxenye ze-ceramic ezicinene nezithuthuke ngokwesakhiwo ngokombono womlando. Izinselelo eziningi zokwenziwa kwezithasiselo ze-ceramic, ezaqala ngaphezu kweminyaka eyishumi kamuva kunezinsimbi nepulasitiki, zingalandelelwa emuva ebunzimeni obukhona bokucubungula izitsha zobumba zesakhiwo, okuhlanganisa izinga lokushisa eliphezulu lokucubungula, izakhiwo zemishini ezingenasici, kanye nezakhiwo ezingezinhle zokucubungula. . Ukuze uvuthwe umkhakha wokukhiqiza okungeziwe kwe-ceramic, i-r&d yesikhathi esizayo kufanele igxile ekwandiseni ukukhethwa kwezinto, ukuthuthukisa ukuphrinta kwe-3D nokulawulwa kwangemva kokucubungula, kanye namakhono ayingqayizivele njengokucubungula kwezinto eziningi kanye nokuxubile. 3 d isigodi sesayensi
"Amalunga" emishini yezimboni
I-Bearing ithathwa “njengokuhlangene” kwemishini yezimboni, ukusebenza kwayo kuthinta ngokuqondile ukusebenza okuthembekile kwemishini emikhulu engaphezu kwethriliyoni eyodwa emnothweni wezwe kanye nenkundla yezokuvikela kazwelonke.
I-All-Ceramic Bearing ibhekisela emikhiqizweni ekhiqizayo yobuchwepheshe obuphezulu eyenziwe ngezinto zobumba, njengeringi yangaphakathi/yangaphandle kanye nomzimba ogoqayo. Ukunemba okuphezulu kwawo wonke ama-ceramic bearings anesidingo esikhulu kumathuluzi omshini we-CNC wasekhaya, ukuvikela izwe, i-aerospace, i-petrochemical, imishini yezokwelapha kanye nezinye izinkambu zobuchwepheshe bemishini ephezulu, futhi izinga labo lokukhiqiza libonisa ukuncintisana okuyinhloko kokukhiqiza okusezingeni eliphezulu kuzwelonke.
Ukwenziwa kwasendaweni kwamabheringi e-ceramic anembile kakhulu emishini esezingeni eliphezulu kubaluleke kakhulu ekuthuthukiseni izinga eliphelele kanye nokuncintisana okuyinhloko kwemboni yasekhaya kanye nemboni yokukhiqiza imishini, kanye nokukhuthaza ukuthuthukiswa kwemishini yasekhaya esezingeni eliphezulu iye kohlakaniphileyo neluhlaza.
Ukusetshenziswa kwe-all-ceramic bearing kumishini ephezulu
Izinto ze-ceramic zobunjiniyela ezisetshenziswa kuwo wonke ama-ceramic bearings ikakhulukazi zifaka i-silicon nitride (Si3N4), i-zirconia (ZrO2), i-silicon carbide (SiC), njll., enezakhiwo ezinhle kakhulu zomzimba namakhemikhali ezingenazo izinto zensimbi zendabuko. Izinzuzo eziyinhloko zama-bearings we-ceramic ezenziwe ngalolu hlobo lwezinto zimi kanje:
(1) Ukuqina kwempahla ye-ceramic yobunjiniyela kuphakeme kakhulu kunokwensimbi evamile enensimbi, futhi impilo yesevisi yazo zonke izinhlobo ze-ceramic zohlobo olufanayo zingandiswa ngaphezu kwama-30% ngaphansi kwezimo ezifanayo zokusebenza;
(2) I-thermal deformation coefficient yezinto zobunjiniyela ze-ceramic ingu-1/4 ~ 1/5 kuphela yaleyo yensimbi enensimbi, futhi i-all-ceramic bear ingabonisa ukumelana nokushaqeka okuhle kokushisisa nokusebenza kwesevisi okuzinzile ngaphansi kwezinga lokushisa eliphakeme kakhulu, izinga lokushisa eliphansi kanye umehluko omkhulu wokushisa izimo zokusebenza;
(3) ukuminyana kwezinto zobumba zobunjiniyela, inertia ejikelezayo namandla e-centrifugal mancane, afanele isivinini esikhulu, namandla okuthwala aqinile, ukumelana nokugqokwa okuhle, izinga lokwehluleka eliphansi;
(4) Izitsha zobumba zobunjiniyela zinokumelana nokugqwala, ukugqunywa kwamagnetoelectric nezinye izici, futhi zinezinzuzo eziphelele ekusebenzeni kokusebenza ngaphansi kokugqwala, inkambu kazibuthe eqinile nezimo zokugqwala kukagesi.
Njengamanje, izinga lokushisa lokugcina lokusebenza kwawo wonke ama-ceramic bearings likwazile ukunqamula ku-1000 ℃, isikhathi esiqhubekayo sokusebenza singafinyelela ngaphezu kuka-50000h, futhi inezici zokuzigcoba, futhi isengaqinisekisa ukunemba kokusebenza nempilo yesevisi ngaphansi. isimo sokungagcolisi. Izici zesakhiwo zawo wonke ama-ceramic bearings zenza nje ukukhubazeka kwama-bearings ensimbi ekusetshenzisweni kobunjiniyela. Banezici ze-ultra-high speed, ukumelana nokushisa okuphezulu / okuphansi, ukumelana nokugqoka, ukumelana nokugqwala, ukufakwa kwe-magnetoelectric, i-oil-free self-lubrication nokunye. Zifanele izindawo ezinokhahlo ngokwedlulele kanye nezimo ezikhethekile zokusebenza, futhi zinamathemba abanzi okufaka isicelo emikhakheni yezobuchwepheshe ephezulu.
Wonke ama-ceramic bearings standard
Muva nje, iKomidi elisebenza ngokujwayelekile le-Chinese Mechanical Engineering Society ligunyaze izindinganiso ezintathu ezilandelayo ezikhishwe ngokusemthethweni.
Ithafa lonke le-ceramic eline-Centribular Plain Bearing (T/CMES 04003-2022)
Ama-Rolling Bearings wonke ama-ceramic Cylindrical roller bearings (T/CMES 04004-2022)
"Ukucaciswa Kwejiyomethri Nokubekezelela Imikhiqizo Ye-Cylindrical Cylindrical All-ceramic Ball Bearing" (T/CMES04005-2022)
Uchungechunge lwamazinga luhlelwa Igatsha Lobunjiniyela Bokukhiqiza le-Chinese Mechanical Engineering Society, futhi liholwa yi-shenyang Jianzhu University (ilabhorethri yobunjiniyela ehlanganyelwe kazwelonke neyendawo "yezinga eliphezulu STONE NUMERICAL control Processing Equipment and Technology"). Uchungechunge lwamazinga luzosetshenziswa ngokusemthethweni ngo-Ephreli 2022.
Lolu chungechunge lwezindinganiso zobuchwepheshe lucacisa imigomo ehlobene, izincazelo, amamodeli athile, ubukhulu, ububanzi bokubekezelela kanye namazinga okukhishwa kwawo wonke ama-bearings ahlangene e-ceramic. Ukuhlukaniswa, ukucubungula izidingo zobuchwepheshe, ukufanisa izidingo zobuchwepheshe kanye nezidingo zobuchwepheshe ze-cutter groove yawo wonke ama-ceramic cylindrical roller bearings; Futhi usayizi nezici zejiyomethri, ukuchezuka komkhawulo kasayizi wokuzisholo kanye nenani lokubekezelela lembobo eyisilinda elithwala wonke amabhola e-ceramic, kuchaza isixhumi esibonakalayo sokusebenza kwawo wonke ama-ceramic bearing (ngaphandle kwe-chamfering). Ngokusekelwe ochungechungeni lwezindinganiso, qhubeka nokulinganisa umklamo ogcwele we-ceramic, ukukhiqizwa, ukuhlanganisa kanye nenqubo yokuhlola, ukuqinisekisa lonke ikhwalithi yokusebenza kwe-ceramic bearing, gwema ukuthwala okugcwele kwe-ceramic ohlelweni lwethu lokucubungula, ukuhlola nokusebenzisa ukulahlekelwa okungadingekile. , iqondise imboni yasekhaya ye-ceramic egcwele intuthuko enempilo futhi ehlelekile, ikhuthaze ukuthwala okugcwele kwe-ceramic ohlelweni lokusebenzisa ukuphepha, ukwethembeka kanye nomnotho, Inethonya elijulile ekuthuthukiseni ukunemba kwemikhiqizo yasekhaya ene-ceramic.
I-China Mechanical Engineering Society (CMES) yinhlangano kazwelonke yezenhlalakahle efanelekayo ukwenza imisebenzi yasekhaya neyamazwe ngamazwe yokumiswa. Kungomunye wokuqukethwe komsebenzi wamazinga e-cMES ukuthuthukisa amazinga e-cMES ukuze kuhlangatshezwane nezidingo zamabhizinisi kanye nemakethe futhi kugqugquzelwe ukusungulwa kanye nokuthuthukiswa kwemboni yemishini. Izinhlangano nabantu baseShayina bangabeka phambili iziphakamiso zokwakhiwa nokubuyekezwa kwamazinga e-cMES futhi babambe iqhaza emsebenzini ofanele.
I-Standalization Working Committee ye-CMES yakhiwe ngochwepheshe abaziwayo abangama-28 abavela emakolishi afuywayo namanyuvesi, izikhungo zocwaningo, amabhizinisi, izikhungo zokuhlola nezitifiketi, njll., kanye namaqembu asebenzayo angama-40 anesibopho sokuthuthukiswa kwamazinga.
