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 kwe-ceramic eyongeziweyo, eyaqala ngaphezulu kweminyaka elishumi emva kwesinyithi kunye nemathiriyeli yeplastiki, inokulandelelwa emva kobunzima obukhoyo bokusetyenzwa kweeseramics zesakhiwo, kubandakanya amaqondo obushushu aphezulu, iipropathi ezinobuthathaka bomatshini, 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 umahluko omkhulu wobushushu kwiimeko zokusebenza;

(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 ngaphezulu kwe-50000h, kwaye lineempawu zokuthambisa, kwaye isenokuqinisekisa ukuchaneka kokusebenza kunye nobomi benkonzo phantsi. imeko yokungathanjiswa. 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 imigangatho yokuthwala i-ceramic

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, ngakumbi 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. , isikhokelo sasekhaya esipheleleyo se-ceramic shishini lophuhliso olunempilo nolucwangcisiweyo, ukukhuthaza ukuthwala i-ceramic epheleleyo kwinkqubo yokusebenzisa ukhuseleko, ukuthembeka kunye noqoqosho, Inempembelelo enzulu ekuphuculeni ukuchaneka kweemveliso ze-ceramic zasekhaya.

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.
