Ikholamu kaGu "Imbali, uPhuhliso kunye neKamva leeCeramics zoMveliso ezoNgezelelweyo" ixoxa ngeentlobo ezisixhenxe zetekhnoloji yoshicilelo lwe-3D ukwenza amacandelo axineneyo kunye nolwakhiwo oluphambili lwe-ceramic ngokwembono yembali. Uninzi lwemiceli mngeni yokwenziwa kwezongezo ze-ceramic, eyaqala ngaphezulu kweminyaka elishumi kamva kunezixhobo zentsimbi kunye neplastiki, inokulandelelwa emva kobunzima obukhoyo bokusetyenzwa kweeseramics zesakhiwo, kubandakanya amaqondo obushushu aphezulu, iipropathi zoomatshini ezinobuthathaka, kunye neepropathi zokusetyenzwa kakubi. Ukuvuthwa intsimi yokwenziwa kwe-ceramic additive, i-r & d yexesha elizayo kufuneka igxininise ekwandiseni ukhetho lwemathiriyeli, ukuphucula ushicilelo lwe-3D kunye nolawulo lwe-post-processing, kunye nezakhono ezizodwa ezifana ne-multi-material kunye ne-hybrid processing. 3 d intlambo yenzululwazi
"Amalungu" ezixhobo zoshishino

I-Bearing ithathwa njenge "joint" yezixhobo zemizi-mveliso, ukusebenza kwayo kuchaphazela ngokuthe ngqo ukusebenza okuthembekileyo kwezixhobo ezinkulu ezingaphezu kwetriliyoni enye kuqoqosho lwesizwe kunye nokhuselo lwesizwe.

I-Ceramic bearing yonke ibhekiselele kwiimveliso ze-high-tech ezenziwe ngezinto ze-ceramic, ezifana nendandatho yangaphakathi / yangaphandle kunye nomzimba ojikelezayo. Ukuchaneka okuphezulu kuzo zonke iibheringi ze-ceramic zinemfuno ebanzi kwizixhobo zomatshini zasekhaya ze-CNC, ukhuselo lwelizwe, i-aerospace, i-petrochemical, izixhobo zonyango kunye nezinye iindawo zeteknoloji yezixhobo eziphezulu, kunye nenqanaba labo lokuvelisa libonisa ukukhuphisana okungundoqo kwimveliso yelizwe eliphezulu.

Ukwenziwa kwasekhaya kweebheringi ze-ceramic ezichanekileyo ze-ultra-precision yezixhobo eziphezulu kubaluleke kakhulu ekuphuculeni inqanaba elipheleleyo kunye nokukhuphisana okungundoqo kwishishini lasekhaya kunye neshishini lokuvelisa izixhobo, kunye nokukhuthaza uphuhliso lwezixhobo zasekhaya eziphezulu ukuya kwizinto ezikrelekrele neziluhlaza.

Ukusetyenziswa kwayo yonke i-ceramic bearing kwizixhobo eziphezulu

Izinto ze-ceramic zobunjineli ezisetyenziswa kuzo zonke iibheringi ze-ceramic ikakhulu ziquka i-silicon nitride (i-Si3N4), i-zirconia (i-ZrO2), i-silicon carbide (i-SiC), njl., ezineempawu ezibalaseleyo zomzimba kunye neekhemikhali ezingenazo izinto zentsimbi zemveli. Iingenelo eziphambili zeebheringi ze-ceramic ezenziwe ngolu hlobo lwemathiriyeli zezi zilandelayo:

(1) Ubunzima bezinto ze-ceramic zobunjineli buphezulu kakhulu kunobuxhakaxhaka bentsimbi eqhelekileyo, kwaye ubomi benkonzo ye-ceramic yohlobo olufanayo bunganyuswa ngaphezu kwe-30% phantsi kweemeko ezifanayo zokusebenza;

2

(3) ingxinano yezinto ze-ceramic yobunjineli, inertia ejikelezayo kunye ne-centrifugal force incinci, ilungele isantya esiphezulu, kunye nomthamo oqinileyo wokuthwala, ukuxhathisa okulungileyo, izinga lokungaphumeleli eliphantsi;

(4) Iiseramikhi zobunjineli zinokumelana nomhlwa, ukugqunyelelwa kwemagnetoelectric kunye nezinye iimpawu, kwaye zinezibonelelo ezipheleleyo ekusebenzeni phantsi komhlwa, umhlaba owomeleleyo wemagnethi kunye neemeko zokuhlwa kombane.

Okwangoku, ubushushu bokusebenza bokugqibela beebheringi ze-ceramic bukwazile ukutyhutyha i-1000 ℃, ixesha eliqhubekayo lokusebenza linokufikelela ngaphezu kwe-50000h, kwaye lineempawu zokuthambisa, kwaye zisenokuqinisekisa ukuchaneka kokusebenza kunye nobomi benkonzo phantsi kwemeko yokungabikho kokuthambisa. Iimpawu zezakhiwo zeebheringi zonke ze-ceramic zenza nje iziphene zeebheringi zetsimbi kwizicelo zobunjineli. Baneempawu ze-Ultra-high speed, ukumelana nobushushu obuphezulu / obuphantsi, ukuxhathisa ukunxiba, ukumelana nokugqwala, ukugqunywa kwe-magnetoelectric, i-oil-free self-lubrication kunye nokunye. Zifanelekele iimeko ezinzima kakhulu kunye neemeko ezikhethekileyo zokusebenza, kwaye zinethuba elibanzi lokufaka isicelo kwiinkalo zobugcisa eziphezulu.

Yonke i-ceramic esemgangathweni umgangatho

Kutshanje, iKomiti eSebenzayo yoMgangatho woMbutho woBunjineli baseTshayina ivume le migangatho mithathu ilandelayo ikhutshwe ngokusemthethweni.

Ithafa lonke le-ceramic elithwele i-Centribular Plain Bearing (T/CMES 04003-2022)

Iibheringi eziqengqelekayo zonke iibheringi zeeramic Cylindrical roller (T/CMES 04004-2022)

"Iinkcazo zejometri kunye nokunyamezelwa kweemveliso zeCylindrical Cylindrical All-ceramic Ball Bearing" (T / CMES04005-2022)

Uluhlu lwemigangatho luququzelelwe yiCandelo lobuNjineli boMveliso ye-Chinese Mechanical Engineering Society, kwaye ikhokelwa yiYunivesithi yase-shenyang Jianzhu (i-laboratory yobunjineli belizwe kunye nengingqi "yenqanaba eliphezulu STONE NUMERICAL control Processing Equipment and Technology"). Olu luhlu lwemigangatho luya kuphunyezwa ngokusemthethweni ngo-Epreli wama-2022.

Olu luhlu lwemigangatho yezobugcisa luchaza imimiselo ehambelanayo, iinkcazo, iimodeli ezithile, imilinganiselo, uluhlu lokunyamezela kunye nemigangatho yokucima yonke i-ceramic joint bearings. Ukwahlula, ukusetyenzwa kweemfuno zobugcisa, ukuthelekisa iimfuno zobugcisa kunye neemfuno zobugcisa ze-cutter groove yazo zonke iibheringi ze-ceramic cylindrical roller; Kwaye ubungakanani kunye neempawu zejometri, ukuphambuka komda wesayizi yegama kunye nexabiso lokunyamezelana kwe-cylindrical hole yonke i-ceramic ball bearing, ichaza i-interface yokusebenza ye-ceramic bearing (ngaphandle kwe-chamfering). Ngokusekwe kuluhlu lwemigangatho, ukuqhubela phambili ukulungelelanisa uyilo olupheleleyo lwe-ceramic, imveliso, indibano kunye nenkqubo yokuvavanya, qinisekisa umgangatho uphela wokusebenza kwe-ceramic bearing, ugweme ukuthwala i-ceramic epheleleyo kwinkqubo yethu yokuvavanya, ukuvavanya kunye nokusetyenziswa kwelahleko engeyomfuneko, ukukhokela ishishini lasekhaya eligcwele i-ceramic enempilo kunye nophuhliso olucwangcisiweyo, ukukhuthaza ukuthwala ngokupheleleyo kwe-ceramic kwinkqubo yokusebenzisa ukhuseleko, ukuthembeka kunye noqoqosho, inempembelelo yokuphucula imveliso yasekhaya.

I-China Mechanical Engineering Society (CMES) ngumbutho wentlalontle wesizwe ofanelekele ukwenza imisebenzi yasekhaya kunye nehlabathi jikelele. Ngomnye wemixholo yomsebenzi wemigangatho ye-cMES ukuphuhlisa imigangatho ye-cMES ukuze kuhlangatyezwane neemfuno zamashishini kunye nokuthengisa kunye nokukhuthaza ukwenziwa kwezinto ezintsha kunye nophuhliso loshishino loomatshini. Imibutho kunye nabantu baseTshayina banokubeka phambili izindululo zokuqulunqwa kunye nohlaziyo lwemigangatho ye-CMES kwaye bathathe inxaxheba kumsebenzi ofanelekileyo.

I-Standardization Working Committee ye-CMES iqulunqwe ziingcali ze-28 ezaziwayo ezivela kwiikholeji zasekhaya kunye neeyunivesithi, amaziko ophando, amashishini, amaziko okuvavanya kunye neziqinisekiso, njl., kunye namaqela asebenzayo angama-40 ajongene nokuphuhliswa kwemigangatho.
