Deep groove ball bearing inozivikanwa nekuvimbika kwayo munzvimbo dzakajairika dzemaindasitiri, asi mainjiniya emazuva ano anowanzoda zvakawanda. Kubva ku tundra yakaomeswa nechando kusvika pakati pechoto, kubva kumabhati emakemikari kusvika kune vacuum yemuchadenga, michina inofanira kushanda mumamiriro ezvinhu anosundira zvikamu kusvika pamiganhu yazvo. Izvi zvinomutsa mubvunzo wakakosha: classic deep ball bearing inogona kutsungirira kunyanyisa kwakadaro, uye yakagadzirwa sei kuti iite izvozvo?
Dambudziko Rinoonekwa: Kupfuura Mamiriro Ekushanda Akajairwa
Nzvimbo dzakanyanyisa dzine kurwiswa kwakasiyana pakuvimbika kwemuviri:
Kupisa Kwakanyanya:Kupisa kusingapfuure zero kunoita kuti mafuta awedzere kukora uye zvinhu zvisashande zvakanaka, nepo tembiricha yepamusoro ichideredza mafuta, ichinyorovesa simbi, uye ichikonzera kuwedzera kwekupisa.
Ngura uye Makemikoro:Kusangana nemvura, maasidhi, maalkali, kana zvinonyungudutsa zvinogona kukurumidza kupinza nekuparadza simbi yakajairwa.
Kusvibiswa: Zvinhu zvinobvisa tsvina zvakanaka (guruva, matombo), zvidimbu zvinofambisa mhepo, kana zvinhu zvine fibrous zvinogona kupinda, zvichikonzera kupera nekukurumidza uye kukuvara kwemagetsi.
Makamuri Anochenesa Anoshandisa Vacuum Yakawanda kana Kuti Anoshandiswa Kuchenesa:Mafuta ekuzora anogona kudzima peturu, zvichisvibisa nharaunda, nepo mafuta akajairwa asingashande.
Mhinduro dzeUinjiniya: Kugadzirisa Standard Bearing
Kuti zvikwanisike kugadzirisa matambudziko aya, bhora remugero rakadzika rinoshandurwa kuburikidza nezvinhu zvakagadzirwa, marapirwo, uye magadzirirwo azvo.
1. Kukunda Kupisa Kwakanyanya
Mabheya Anodziya Nekupisa Kwakanyanya: Shandisa simbi dzinodziya (senge simbi dzezvishandiso), mafuta anodziya nekupisa kwakanyanya akagadzirwa (silicone, perfluoropolyether), uye macage akagadzirwa nesimbi yakaputirwa nesirivha kana mapolymer anodziya nekupisa kwakakwirira (polyimide). Izvi zvinogona kushanda nguva dzose pakupisa kunodarika 350°C.
Mabheya eCryogenic: Akagadzirirwa mapombi egasi akanyungudutswa uye mashandisirwo emuchadenga. Anoshandisa zvinhu zvinoramba zvakasimba patembiricha yakaderera (semuenzaniso, simbi dzisina ngura), mafuta akakosha senge molybdenum disulfide kana PTFE-based compounds, uye kucheneswa kwakanyatsojeka kwemukati kuti zviverengere kusimba kwakanyanya kwechinhu.
2. Kurwisa Kuora Nemakemikari
Mabheya eSimbi Isina Kuora: Dziviriro huru. Simbi Isina Kuora yeMartensitic 440C inopa kusimba uye kuramba ngura zvakanaka. Kune nzvimbo dzine hukasha (zvekudya, zvemishonga, zvemugungwa), mabhora esimbi isina kuora yeAISI 316 kana ceramic (silicon nitride) anoshandiswa.
Mapendi Akakosha uye Marapirwo: Pamusoro payo panogona kuputirwa ne black oxide, zinc-nickel, kana ma polymers akagadzirwa senge Xylan® kuti pave nekudzivirira kusingaparadzike kubva kune zvinoparadza.
3. Kuvhara Kusvibiswa
Munzvimbo dzakasviba zvakanyanya kana kuti dzakanyorova, sisitimu yekuvharira ndiyo nzira yekutanga yekudzivirira. Izvi zvinopfuura zvisimbiso zverabha zvemazuva ese.
Mhinduro dzeKuvhara Dzinorema: Zvivharo zvekubata zvine miromo mitatu, zvakagadzirwa nezvinhu zvisingapindike nemakemikari zvakaita seFKM (Viton®), zvinoshandiswa. Kune nzvimbo dzinonyanya kukwesha, zvivharo zve labyrinth pamwe chete nemasisitimu ekuchenesa mafuta zvinogona kutsanangurwa kuti zvigadzire chipingamupinyi chisingapindike.
4. Kushanda munzvimbo dzakakosha
Mabheringi eVacuum neCleanroom: Shandisa simbi dzakabviswa mweya uye mafuta akaomeswa (semuenzaniso, sirivha, goridhe, kana MoS2 coatings) kana kuti akagadzirwa kuti ashande asina mafuta ane zvikamu zveceramic kudzivirira kubuda kwemweya.
Mabheya Asiri eMagineti: Anodiwa mumichina yeMRI nemidziyo chaiyo. Izvi zvakagadzirwa nesimbi dzisina ngura dzinoshandiswa neaustenitic (AISI 304) kana zveceramics, zvichiita kuti pasave nekupindirana kwemagineti.
Kutariswa Kwemashandisirwo: Apo Mabheya Akanyanya Anoratidza Kukosha Kwawo
Kugadziriswa Kwechikafu Nechinwiwa: Mabheya esimbi isina tsvina 316 ane mafuta anotenderwa neFDA anokwanisa kutsungirira kushambidzwa kwezuva nezuva nemagetsi anochenesa.
Kuchera & Kuchera: Mabheringi ane zvisimbiso zvinorema zvakanyanya uye tungsten carbide coatings anogara mumapombi ane matope uye macrusher azere nematope anogumbura.
MaActuator emuchadenga: Mabheringi akareruka, anoenderana ne vacuum anovimbisa kushanda kwakavimbika kana tembiricha yakanyanya uye kumanikidzwa kwekubhururuka.
Mhedziso: Bhiza Rinochinjika
Kubata bhora kwakadzika kunoratidza kuti dhizaini yakanaka inogona kugadziriswa kuti ibudirire chero kupi. Nekusarudza zvinhu, mafuta ekuzora, zvisimbiso, uye kurapwa kwekupisa, mainjiniya vanogona kusarudza bhora rakadzika risiri chinhu chakajairika, asi mhinduro yakagadzirwa nehunyanzvi hwekurarama. Kugona kuchinjika uku kunoita kuti kunyangwe mumamiriro ezvinhu akaomarara epasi, misimboti yekutenderera kwakapfava uye kwakavimbika inogona kugara. Kutsanangura bhora rakakodzera rekunze kwakanyanyisa hakusi mari yekuwedzera - kutenga mari mukushanda kwenguva yakavimbiswa uye kubudirira kwebasa.
