Kuwedzera kudiwa kwekuvandudza kuvimbika muindasitiri yese zvinoreva mainjiniya anofanirwa kufunga nezvese zvikamu zvemidziyo yavo.Kutakura masisitimu zvikamu zvakakosha mumuchina uye kutadza kwavo kunogona kuve nenjodzi uye inodhura mhedzisiro.Iyo yekubereka dhizaini ine mhedzisiro yakakura pakuvimbika, kunyanya mumamiriro ekushanda akanyanya kusanganisira kutonhora kwakanyanya kana kuderera, vacuum uye corrosive atmospheres.Ichi chinyorwa chinodonongodza zvinofanirwa kutora kana uchitsanangura mabhengi enzvimbo dzinonetsa, saka mainjiniya anogona kuona kuvimbika kwepamusoro uye kuita kwakanakisa kwehupenyu hurefu hwemidziyo yavo.

Iyo inotakura sisitimu inosanganisa zvinhu zvakawanda zvinosanganisira mabhora, mhete, makeji uye lubrication semuenzaniso.Mabheji akajairwa haawanzo mira kune kuomarara kwenzvimbo dzakaomarara uye saka kutarisisa kwakakosha kune zvikamu zvega kunoda kutorwa.Iwo akanyanya kukosha maatomu ekuzora, zvishandiso, uye yakakosha kupisa kupisa kana machira uye nekutarisa chinhu chimwe nechimwe zvinoreva kuti mabearings anogona kunyatso gadziridzwa application.

Kushanda pakupisa kwakanyanya

Yepamusoro tembiricha yekushandisa, senge iyo inoshandiswa mune actuation masisitimu mukati meiyo aerospace indasitiri inogona kuunza matambudziko kune akajairwa mabheji.Uyezve, tembiricha iri kukwira mumidziyo sezvo mayunitsi ari kuwedzera madiki uye akawedzera simba-density, uye izvi zvinounza dambudziko kune avhareji kubereka.

Lubrication

Lubrication chinhu chakakosha kufunga pano.Mafuta uye magirisi ane tembiricha yakanyanya kushanda panguva iyo inozotanga kudzikisira uye kubuda evapote nekukurumidza zvichitungamira mukutadza kubereka.Magirisi akajairwa anowanzo kuganhurirwa kune tembiricha yepamusoro inosvika 120°C uye mamwe magirosi akajairwa etembiricha yepamusoro anokwanisa kuramba tembiricha inosvika 180°C.

Zvisinei, kune zvikumbiro zvinoda kunyange tembiricha yepamusoro-soro magirosi ekuzora ane fluorinated anowanikwa uye tembiricha inodarika 250°C inokwanisika.Iko kusingagoneke kukwirisa kwemvura, lubrication yakasimba isarudzo inobvumira kushanda kwakadzikama kwakavimbika pane tembiricha yakanyanya.Muchiitiko ichi molybdenum disulphide (MOS2), tungsten disulphide (WS2), graphite kana Polytetrafluoroethylene (PTFE) inokurudzirwa semafuta akasimba sezvo ichikwanisa kushivirira kupisa kwakanyanya kwenguva yakareba.

Zvishandiso

Kana zvasvika kune tembiricha inodarika 300 ° C yakakosha mhete uye zvinhu zvebhora zvinodiwa.AISI M50 isimbi yekushisa yakakwira iyo inowanzokurudzirwa sezvo ichiratidzira kupfeka kwakanyanya uye kuramba kuneta pakupisa kwakanyanya.BG42 imwe simbi yetembiricha yakakwira ine kuoma kwakanaka kwekupisa pa300 ° C uye inowanzotsanangurwa sezvo iine mwero wepamusoro wekupokana uye haitani kuneta nekupfeka pakupisa kwakanyanya.

Makeji etembiricha akakwira anodiwa zvakare uye anogona kupihwa mune akakosha mapolymer zvinhu zvinosanganisira PTFE, Polyimide, Polyamide-imide (PAI) uye Polyether-ether-ketone (PEEK).Kune tembiricha yakakwira oiri masisitimu anotakura matanga anogona zvakare kugadzirwa kubva kubhuronzi, ndarira kana sirivheri-yakaputirwa simbi.

Coatings uye kupisa kurapwa

Machira epamberi uye kurapwa kwepamusoro kunogona kuiswa kumabhengi kurwisa kukwesha, kudzivirira ngura uye kuderedza kusakara, nekudaro kunatsiridza kutakura mashandiro pakupisa kwakanyanya.Semuenzaniso, matanga esimbi anogona kuputirwa nesirivha kuti avandudze kushanda uye kuvimbika.Panyaya yekutadza kwemafuta / nzara, iyo sirivha-plating inoita senge mafuta akasimba, achibvumira kutakura kuenderera mberi nekumhanya kwenguva pfupi kana mune emergency.

Kuvimbika pakupisa kwakadzika

Kune rumwe rutivi rwechiyero, tembiricha yakaderera inogona kunetsa kune akajairwa mabhengi.

Lubrication

Mune tembiricha yakaderera, semuenzaniso cryogenic kupomba maapplication ane tembiricha munzvimbo ye -190 ° C, mafuta ekuzora anoita waxy zvichikonzera kutadza kubereka.Solid lubrication senge MOS2 kana WS2 yakanakira kuvandudza kuvimbika.Uyezve, mumashandisirwo aya, midhiya iri kupombwa inogona kuita semafuta, saka mabearings anofanirwa kunyatso gadziridzwa kuti ashande pane idzi tembiricha dzakaderera uchishandisa zvinhu zvinoshanda nema media.

Zvishandiso

Chimwe chinhu chinogona kushandiswa kuvandudza hupenyu hwekuneta uye kusamira kwekusapfeka iSV30® - martensitic kuburikidza-yakaomeswa, yakakwira nitrogen, simbi isingaviri.Mabhora eCeramic anokurudzirwawo sezvaanopa kuita kwepamusoro.Izvo zvemukati mechanicha zvimiro zvechinyorwa zvinoreva kuti vanopa mashandiro akanaka mumamiriro asina kunaka ekuzora, uye inokodzera zvirinani kushanda zvakavimbika pane yakaderera tembiricha.

Cage zvinhu zvinofanirwawo kusarudzwa kuti zviite sezvisingapfeki sezvinobvira uye sarudzo dzakanaka pano dzinosanganisira PEEK, Polychlorotrifluoroethylene (PCTFE) uye PAI mapurasitiki.

Kurapa kwekupisa

Mhete dzinofanirwa kunyatsogadziriswa kupisa kuti ivandudze kugadzikana kwepazasi tembiricha.

Mukati magadzirirwo

Imwezve fungidziro yekushanda mukudziya kwakadzikira ndiyo dhizaini yemukati mebearing.Mabearings akagadzirwa ane mwero we radial play, asi sezvo tembiricha inodzikira, izvo zvinotakura zvinopinda mukupisa kwekupisa uye huwandu hweradial play saka hushoma.Kana iyo nhanho yeradial play yakadzikira kusvika zero panguva yekushanda izvi zvinoguma nekutadza kubereka.Mabearings anoitirwa yakaderera tembiricha maapplication anofanirwa kugadzirwa neakawanda radial play pane tembiricha yekamuri kubvumira nhanho inogamuchirika yekushanda radial kutamba pane yakaderera tembiricha.

Kubata kudzvanywa kwevacuum

Mumamiriro ekupedzisira-akakwira vacuum akadai seaya aripo mukugadzira zvemagetsi, semiconductors uye maLCD, kudzvanywa kunogona kuderera kupfuura 10-7mbar.Ultra-yakakwirira vacuum mabhengi anowanzo shandiswa muactuation midziyo mukati menzvimbo yekugadzira.Imwe yakajairika vacuum application ndeye turbomolecular pombi (TMP) iyo inoburitsa vacuum yekugadzira nharaunda.Mune iyi yekupedzisira application mabearings anowanzo kudiwa kuti ashande nekumhanya kukuru.

Lubrication

Kuzora mumamiriro ezvinhu aya kwakakosha.Pamavacuums akadai, magirosi ekuzora anoputika uye anobuda kunze, uye kushomeka kwekuzora kunoshanda kunogona kukonzera kutadza kubereka.Special lubrication saka inoda kushandiswa.Kune yakakwira vacuum nharaunda (kudzika kusvika 10-7 mbar) PFPE magirisi anogona kushandiswa sezvo aine yakanyanya kupikisa kusimuka.Kune ekupedzisira-yakakwira vacuum nharaunda (10-9mbar uye pazasi) yakasimba lubricant uye machira anoda kushandiswa.

Kune epakati vacuum nharaunda (yakatenderedza 10-2mbar), nekungwarira dhizaini uye kusarudzwa kweakakosha vacuum girisi, anotakura masisitimu anoburitsa nguva yehupenyu hurefu hweanopfuura maawa makumi mana ezviuru (anenge makore mashanu) ekushandisa nguva dzose, uye anoshanda nekumhanya kwakanyanya, anogona kubudirira.

Corrosion resistance

Mabearings anoitirwa kushandiswa munzvimbo ine ngura anofanirwa kugadzirwa zvakanyanya sezvo achigona kuoneswa maacids, alkalis uye mvura yemunyu pakati pemamwe makemikari anoparadza.

Zvishandiso

Zvishandiso chinhu chakakosha kutariswa kune nharaunda dzine ngura.Simbi dzine simbi dzakajairwa dzinoita ngura zviri nyore, zvichikonzera kutadza kubereka kwekutanga.Muchiitiko ichi, SV30 mhete yemidziyo ine mabhora eceramic inofanirwa kutariswa sezvo ichipokana zvakanyanya nekuora.Asi izvo, zvidzidzo zvakaratidza kuti SV30 zvinhu zvinogona kugara zvakapetwa nguva yakareba kupfuura imwe simbi isingaite ngura munzvimbo yekupfapfaidza munyu.Mukudzorwa kwemunyu-spray miedzo SV30 simbi inongoratidza zviratidzo zvishoma zvekuora mushure memaawa 1,000 ekuedzwa kwepfapfaidzo yemunyu (ona girafu 1) uye SV30's high corrosion resistance inoonekwa zvakajeka pamarin'i ekuedza.Yakakosha ceramic bhora zvinhu zvakaita seZirconia neSilicon Carbide zvinogona zvakare kushandiswa kuwedzera kutakura kuramba kune zvinoparadza zvinhu.

Kuwana zvakawanda kubva kune media lubrication

Iyo yekupedzisira inonetsa nharaunda ndeye maapplication apo midhiya inoita semafuta ekuzora, semuenzaniso mafiriji, mvura, kana hydraulic fluid.Mune ese maapplication aya zvinhu ndizvo zvakanyanya kutariswa, uye SV30 - ceramic hybrid bearings kazhinji yakawanikwa ichipa iyo inonyanya kushanda uye yakavimbika mhinduro.

Mhedziso

Mamiriro ezvinhu akanyanya anopa matambudziko mazhinji ekushanda kune akajairwa mabhengi, nokudaro achikonzera kuti akundikane nguva isati yakwana.Mune aya mabheji ekushandisa anofanirwa kunyatso gadziridzwa kuitira kuti aenderane nechinangwa uye ape yakanakisa kuita kwenguva refu.Kuti ive nechokwadi chekuvimbika kwepamusoro kwemabheya kutarisisa kwakanyanya kunofanirwa kubhadharwa kune lubrication, zvinhu, mapeji epamusoro uye kurapwa kwekupisa.
