Kuphunzira Mozama Mitundu ya Ma Air Bearings ndi Linear Motion Guide Systems

Mu gawo lalikulu la kupanga zinthu pogwiritsa ntchito nanometer, zofooka zakuthupi za makina ogwiritsira ntchito kulumikizana zakhala vuto lalikulu. Pamene atsogoleri amakampani akulimbikitsa kuti pakhale kufalikira mwachangu komanso kutsimikizika kwakukulu mu semiconductor lithography ndi kuwunika kwa ndege, kudalira ukadaulo wapamwamba wonyamula mpweya kwasintha kuchoka pa malo apamwamba kupita ku kufunika kwa mafakitale. Kumvetsetsa mitundu yosiyanasiyana ya mabearing a mpweya ndi chinthu chofunikira kwambiri pakulimba kwa mainjiniya onyamula mpweya ndikofunikira kwa mainjiniya aliyense wopanga mibadwo yotsatira ya machitidwe otsogolera oyenda molunjika.

Kumvetsetsa Mitundu Yoyamba ya Ma Air Bearings

Ukadaulo wonyamula mpweya umagwira ntchito motsatira mfundo ya filimu yopyapyala kwambiri ya mpweya wopanikizika womwe umathandizira katundu, zomwe zimathandiza kuthetsa kukangana, kusowa, ndi kutentha komwe kumakhudzana ndi mabearing amakina. Komabe, njira yogawa mpweya imafotokoza momwe bearing imagwirira ntchito.

Ma Porous Media Air Bearings nthawi zambiri amaonedwa ngati muyezo wabwino kwambiri wogawa mphamvu mofanana. Pogwiritsa ntchito zinthu zokhala ndi ma porous—nthawi zambiri kaboni kapena zoumba zapadera—mpweya umakakamizika kudutsa m'mabowo mamiliyoni ambiri a sub-micron. Izi zimapangitsa kuti mpweya ukhale wolimba kwambiri womwe sungagwedezeke kwambiri ndipo umapereka chinyezi chabwino.

Ma Orifice Air Bearings amagwiritsa ntchito mabowo kapena mipata yokonzedwa bwino kuti agawire mpweya. Ngakhale kuti nthawi zambiri izi zimakhala zosavuta kupanga, zimafuna akatswiri aukadaulo kuti azitha kuyang'anira "kuchepetsa kupanikizika" komwe kumafunika kuti apewe kusakhazikika pa liwiro lalikulu.

Ma Flat Pad Air Bearings ndi mahatchi ogwirira ntchito kwambiri a machitidwe owongolera mayendedwe olunjika. Izi nthawi zambiri zimayikidwa m'magulu awiri osiyana kuti "zikweze" njanji ya granite, zomwe zimapangitsa kuti zikhale zolimba kwambiri mbali zosiyanasiyana.

Ma Rotary Air Bearings amapereka mayendedwe olakwika pafupifupi zero pa ntchito monga goniometry kapena spindle testing. Kutha kwawo kusunga axis yozungulira nthawi zonse popanda "kugwedezeka" kwa ma ball bearings kumapangitsa kuti akhale ofunikira kwambiri pa optical centering.

Chiyerekezo cha Uinjiniya cha Kupambana: Chitsogozo cha Kunyamula Mpweya Kuuma

Limodzi mwa malingaliro olakwika omwe amafala kwambiri mu metrology ndi lakuti ma air bearing ndi "ofewa" poyerekeza ndi ma mechanical roller. Zoona zake n'zakuti, kuuma kwamakono kwa air bearing guide kumatha kupitirira kwa makina akapangidwa bwino.

Kuuma kwa dongosolo lonyamula mpweya kumatanthauza kusintha kwa makulidwe a filimu ya mpweya chifukwa cha kusintha kwa katundu. Izi zimachitika kudzera mu "kuyika patsogolo." Pogwiritsa ntchito maginito kapena kupanikizika kwa vacuum—kapena pogwira njanji ya granite yokhala ndi ma air pads otsutsana—mainjiniya amatha kukanikiza filimu ya mpweya. Pamene filimuyo ikuyamba kuonda, kukana kwake kukanikiza kwina kumawonjezeka kwambiri.

Kulimba kwambiri n'kofunika kwambiri chifukwa kumalamulira kuchuluka kwachilengedwe kwa makinawa komanso kuthekera kwake kupirira kusokonezeka kwakunja, monga mphamvu zopangidwa ndi mota yothamanga kwambiri. Ku ZHHIMG, timagwiritsa ntchito mphamvu zamagetsi (CFD) kuti tiwongolere kusiyana pakati pa bearing ndichitsogozo cha granite, kuonetsetsa kuti kuuma kwa thupi kumakulitsidwa popanda kusokoneza chibadwa cha kayendedwe kake.

Kusintha kwa Machitidwe Otsogolera Oyenda Molunjika

Kuphatikizidwa kwa ma bearing a mpweya mu machitidwe owongolera kuyenda kolunjika kwasintha kapangidwe ka makina amakono. Mwachikhalidwe, malangizo olunjika anali ndi njanji yachitsulo ndi ngolo yozungulira mpira. Ngakhale kuti ndi yolimba, machitidwe awa amavutika ndi "kuzungulira" ndi kutentha.

Dongosolo lamakono lowongolera mzere wolondola kwambiri tsopano nthawi zambiri limakhala ndi granite, yomwe imapereka kusalala kofunikira komanso kusakhala ndi kutentha, limodzi ndi chikwama chonyamula mpweya. Kuphatikiza kumeneku kumalola:

• Kukangana kosasinthasintha (kusinthasintha), zomwe zimathandiza kuti zinthu ziyende pang'onopang'ono.

• Moyo wopanda malire, popeza palibe kuwonongeka kwa makina pakati pa zigawozo.

• Makhalidwe odziyeretsa okha, chifukwa mpweya wotuluka nthawi zonse umaletsa fumbi kulowa mumpata wonyamula.

Udindo wa Opanga Ukadaulo wa Air Bearing mu Industry 4.0

Kusankha pakati pa opanga ukadaulo wonyamula mpweya kumaphatikizapo kuwunika zambiri osati kungonyamula kokha. Zomwe zimayendetsedwa bwino kwambiri ndi zomwe zimagwiritsa ntchito chitsulo chonyamula mpweya, njanji yotsogolera, ndi kapangidwe kothandizira ngati dongosolo limodzi logwirizana.

Monga wopanga wapadera, ZHHIMG Group imalumikiza kusiyana pakati pa sayansi ya zinthu ndi mphamvu yamadzimadzi. Timapanga zinthu za granite zomwe zimagwiritsidwa ntchito ngati "njira yoyendera" ya mafilimu amlengalenga awa. Chifukwa chakuti mpweya wozungulira umakhala wolondola ngati pamwamba pomwe umawulukira, kuthekera kwathu kozungulira granite kufika pamlingo wapansi pa micron ndi komwe kumalola makina athu oyenda molunjika kuti akwaniritse kubwerezabwereza kwa nanometer.

Kufunika kwa machitidwe awa kukuchulukirachulukira mu gawo loyang'anira ma semiconductor, komwe kusamukira ku ma node a 2nm ndi 1nm kumafuna magawo omwe sangasunthe popanda kugwedezeka konse. Mofananamo, mu gawo la ndege, kuyeza kwa zigawo zazikulu za turbine kumafuna mphamvu yolemera ya granite pamodzi ndi kukhudza kofewa kwa ma probe othandizidwa ndi mpweya.

Kutsiliza: Kukhazikitsa Muyezo wa Kuyenda kwa Madzi

Kusintha kuchoka pa kukhudzana ndi makina kupita ku chithandizo cha filimu yamadzimadzi kumayimira kusintha kwa njira yaukadaulo wamakina. Mwa kumvetsetsa mphamvu zenizeni za mitundu yosiyanasiyana ya ma bearing a mpweya ndikuyang'ana kwambiri kufunika kofunikira kwakuuma kwa chitsogozo chonyamula mpweya, opanga amatha kukwaniritsa kulondola komwe kale kunkaganiziridwa kuti n'kosatheka.

Ku ZHHIMG, tadzipereka kukhala ochulukirapo kuposa kungopereka zinthu zina. Ndife ogwirizana nawo pa nkhani yolondola, kupereka maziko olimba komanso ukadaulo wapamwamba wonyamula mpweya wofunikira kuti tiyendetse tsogolo la zatsopano padziko lonse lapansi. Pamene kuyenda kulibe kukangana, mwayi wolondola umakhala wopanda malire.
