Malinga ndi kafukufuku wamsika wa 3D Science Valley, makampani osindikiza a ceramic 3D amayang'ana kwambiri kafukufuku ndi chitukuko cha makina ndi zipangizo zosindikizira za ceramic 3D zomwe zimapanga zinthu zosiyanasiyana, pomwe ukadaulo wosindikiza wa 3D wokhala ndi mtengo wotsika komanso wolondola kwambiri umalowa mumsika. Njira yatsopano yopangira zowonjezera za ceramic ndikulowa m'munda wopanga zinthu zamtengo wapatali, kuphatikiza antenna ya ceramic 5G, ceramic collimator, zigawo za nyukiliya, ma bearing a ceramic...
Posachedwapa, China Mechanical Engineering Society yatulutsa mwalamulo magulu atatu a ceramic bearing series.

"Zolumikizira" za zida zamafakitale
Bearing imaonedwa ngati "cholumikizira" cha zida zamafakitale, magwiridwe ake amakhudza mwachindunji magwiridwe antchito odalirika a zida zazikulu zoposa 1 trilioni mu chuma cha dziko ndi chitetezo cha dziko.
Mabendi a ceramic onse ndi zinthu zamakono zopangidwa ndi zinthu zadothi, monga mphete yamkati/yakunja ndi thupi lozungulira. Mabendi a ceramic onse ndi olondola kwambiri amafunidwa kwambiri m'zida zamakina za CNC zapakhomo, chitetezo cha dziko, ndege, petrochemical, zida zamankhwala ndi madera ena apamwamba aukadaulo wa zida, ndipo kuchuluka kwawo kopanga kukuwonetsa mpikisano waukulu wa kupanga zinthu zapamwamba zadziko lonse.
Kukhazikitsa malo a mabearing a ceramic olondola kwambiri a zida zapamwamba ndikofunikira kwambiri pakukweza mulingo wonse ndi mpikisano waukulu wamakampani opanga zida zam'nyumba, ndikulimbikitsa chitukuko cha zida zapamwamba zam'nyumba kukhala zanzeru komanso zobiriwira.
Kugwiritsa ntchito zida zonse za ceramic mu zida zapamwamba
Zipangizo za ceramic zaukadaulo zomwe zimagwiritsidwa ntchito mu ma bearing a all-ceramic makamaka zimaphatikizapo silicon nitride (Si3N4), zirconia (ZrO2), silicon carbide (SiC), ndi zina zotero, zomwe zili ndi mphamvu zabwino kwambiri zakuthupi ndi zamakemikolo kuposa zipangizo zachitsulo zachikhalidwe. Ubwino waukulu wa ma bearing a all-ceramic opangidwa ndi zinthu zamtunduwu ndi awa:
(1) Kulimba kwa zinthu za ceramic zaukadaulo kuli kwakukulu kwambiri kuposa kwa chitsulo wamba, ndipo nthawi yogwira ntchito ya ceramic yonse yamtundu womwewo ikhoza kuwonjezeka ndi oposa 30% pansi pa mikhalidwe yofanana yogwirira ntchito;
(2) Chiŵerengero cha kutentha kwa zinthu za ceramic zaukadaulo ndi 1/4 ~ 1/5 yokha ya chitsulo chonyamula, ndipo chonyamula cha ceramic chokha chingasonyeze kukana kutentha bwino komanso kugwira ntchito bwino pa kutentha kwambiri, kutentha kochepa komanso kusiyana kwakukulu kwa kutentha;
(3) kachulukidwe ka zinthu za ceramic, rotational inertia ndi mphamvu ya centrifugal ndi zazing'ono, zoyenera kuthamanga kwambiri, komanso mphamvu yamphamvu yonyamula, kukana bwino kuvala, komanso kulephera kochepa;
(4) Zida zauinjiniya zimakhala ndi mphamvu yolimbana ndi dzimbiri, mphamvu yoteteza maginito ndi zina, ndipo zimakhala ndi ubwino waukulu pakugwira ntchito bwino pansi pa mphamvu yowononga, mphamvu ya maginito yamphamvu komanso mphamvu yamagetsi yowononga.
Pakadali pano, kutentha kogwira ntchito kwa ma bearing a ceramic onse kwatha kupyola 1000℃, nthawi yogwira ntchito yopitilira imatha kufika pa 50000h, ndipo ili ndi mawonekedwe odzipaka mafuta okha, ndipo imathabe kutsimikizira kulondola kwa ntchito ndi moyo wautumiki popanda mafuta. Makhalidwe a kapangidwe ka ma bearing a ceramic onse amangowonjezera zolakwika za ma bearing achitsulo mu ntchito zauinjiniya. Ali ndi mawonekedwe a liwiro lapamwamba kwambiri, kukana kutentha kwambiri/kotsika, kukana kutopa, kukana dzimbiri, kutchinjiriza kwa magnetoelectric, kudzipaka mafuta popanda mafuta ndi zina zotero. Ndi oyenera malo ovuta kwambiri komanso mikhalidwe yapadera yogwirira ntchito, ndipo ali ndi mwayi wogwiritsidwa ntchito m'magawo apamwamba aukadaulo.
Zonse zotengera za ceramic
Posachedwapa, Komiti Yogwira Ntchito Yoyimira Malamulo ya The Chinese Mechanical Engineering Society yavomereza miyezo itatu yotsatirayi yomwe yatulutsidwa mwalamulo.

"Mafotokozedwe a Geometric ndi Kulekerera kwa Zogulitsa Zonyamula Mipira Zozungulira Zozungulira Zonse za Ceramic" (T/CMES04005-2022)
Mndandanda wa miyezo umakonzedwa ndi Production Engineering Branch ya Chinese Mechanical Engineering Society, ndipo umatsogozedwa ndi shenyang Jianzhu University (laboratori yaukadaulo yadziko lonse komanso yakomweko ya "Zida Zoyendetsera Zinthu ndi Ukadaulo Wapamwamba wa STONE NUMERICAL"). Mndandanda wa miyezowu udzakhazikitsidwa mwalamulo mu Epulo 2022.
Mndandanda wa miyezo yaukadaulo uwu umatchula mawu ofanana, matanthauzidwe, mitundu yeniyeni, miyeso, kuchuluka kwa kulekerera ndi miyezo yochotsera ya ma bearing olumikizana a ceramic. Kugawa, zofunikira zaukadaulo zokonza, zofunikira zaukadaulo zofanana ndi zofunikira zaukadaulo zodulira ma bearing ozungulira a ceramic; Ndipo kukula ndi mawonekedwe a geometric, kupotoka kwa malire a kukula ndi mtengo wololera wa bearing ozungulira a mpira wa ceramic, kumatanthauzira mawonekedwe ogwirira ntchito a bearing ozungulira a ceramic (kupatula chamfering). Kutengera mndandanda wa miyezo, onjezerani kapangidwe ka bearing ozungulira a ceramic, kupanga, kusonkhanitsa ndi kuyesa, kutsimikizira mtundu wonse wa magwiridwe antchito a bearing ozungulira, kupewa bearing ozungulira a ceramic munthawi yathu yokonza, kuyesa ndi kugwiritsa ntchito kutayika kosafunikira, kutsogolera makampani opanga bearing ozungulira a ceramic okhala ndi thanzi komanso olongosoka, kulimbikitsa bearing ozungulira a ceramic munjira yogwiritsira ntchito chitetezo, kudalirika komanso ndalama, Zimakhudza kwambiri kukonza kulondola kwa zinthu zonyamula bearing ozungulira a ceramic.
China Mechanical Engineering Society (CMES) ndi bungwe ladziko lonse lodziwa bwino ntchito zokhudzana ndi chikhalidwe cha anthu lomwe limagwira ntchito zokhazikitsa miyezo m'dziko muno komanso padziko lonse lapansi. Ndi chimodzi mwa ntchito zomwe zili mu miyezo ya cMES kupanga miyezo ya cMES kuti ikwaniritse zosowa za mabizinesi ndi msika ndikulimbikitsa luso ndi chitukuko cha makampani opanga makina. Mabungwe ndi anthu ku China angapereke malingaliro oti apange ndikukonzanso miyezo ya cMES ndikutenga nawo mbali pantchito yoyenera.
Komiti Yogwira Ntchito Yokhazikika ya CMES imapangidwa ndi akatswiri odziwika bwino 28 ochokera m'makoleji ndi mayunivesite am'deralo, mabungwe ofufuza, mabizinesi, mabungwe oyesa ndi kupereka satifiketi, ndi zina zotero, ndipo magulu 40 ogwira ntchito akatswiri ndi omwe ali ndi udindo wopanga miyezo.
