Kuwonjezeka kwakufunika kuti apititse patsogolo kudalirika kwamakampani onse kumatanthauza kuti mainjiniya ayenera kuganizira zigawo zonse za zida zawo.Makina onyamula ndi gawo lofunikira pamakina ndipo kulephera kwawo kumatha kukhala ndi zotsatira zowopsa komanso zokwera mtengo.Kapangidwe kameneka kamakhudza kwambiri kudalirika, makamaka m'malo ogwirira ntchito kwambiri kuphatikiza kutentha kwambiri kapena kutsika, vacuum ndi mlengalenga wowononga.Nkhaniyi ikufotokoza zomwe muyenera kuziganizira pofotokoza za malo ovuta, kotero mainjiniya amatha kuwonetsetsa kuti zida zawo ndizodalirika komanso zimagwira ntchito kwanthawi yayitali.

Dongosolo lonyamula lili ndi zinthu zambiri kuphatikiza mipira, mphete, makola ndi mafuta mwachitsanzo.Ma bearings okhazikika nthawi zambiri samalimbana ndi kuuma kwa malo ovuta ndipo chifukwa chake ndikofunikira kuganizira kwambiri magawo omwewo.Zinthu zofunika kwambiri ndizopaka mafuta, zida, chithandizo chapadera cha kutentha kapena zokutira ndipo poyang'ana chinthu chilichonse chimatanthawuza kuti mayendedwe amatha kukonzedwa bwino kuti agwiritse ntchito.

Kugwira ntchito pa kutentha kwakukulu

Kugwiritsa ntchito kutentha kwakukulu, monga komwe kumagwiritsidwa ntchito m'makina oyendetsa ndege mumsika wazamlengalenga kumatha kubweretsa zovuta pamayendedwe wamba.Kuphatikiza apo, kutentha kukukwera pazida pomwe mayunitsi akucheperachepera komanso akuchulukirachulukira mphamvu, ndipo izi zimapangitsa kuti pakhale vuto lalikulu.

Kupaka mafuta

Kupaka mafuta ndikofunikira kwambiri pano.Mafuta ndi mafuta amakhala ndi kutentha kwakukulu kogwira ntchito komwe kumayamba kutsika ndikutuluka nthunzi mwachangu zomwe zimapangitsa kulephera kubereka.Mafuta okhazikika nthawi zambiri amakhala ndi kutentha kwambiri kwa pafupifupi 120 ° C ndipo mafuta ena odziwika bwino amatha kupirira kutentha mpaka 180 ° C.

Komabe, pa ntchito zomwe zimafuna kutentha kwambiri, mafuta apadera opaka mafuta opangidwa ndi fluorinated amapezeka ndipo kutentha kopitilira 250 ° C ndikotheka.Kumene kutsekemera kwamadzimadzi sikungatheke, kuyatsa kolimba ndi njira yomwe imalola kuti pakhale ntchito yodalirika yotsika kwambiri pa kutentha kwakukulu.Pamenepa molybdenum disulphide (MOS2), tungsten disulphide (WS2), graphite kapena Polytetrafluoroethylene (PTFE) akulimbikitsidwa kukhala mafuta olimba chifukwa amatha kupirira kutentha kwambiri kwa nthawi yaitali.

Zipangizo

Zikafika pa kutentha kopitilira 300 ° C mphete yapadera ndi zida za mpira ndizofunikira.AISI M50 ndi chitsulo chotentha kwambiri chomwe chimalimbikitsidwa chifukwa chimawonetsa kuvala kwambiri komanso kukana kutopa pakutentha kwambiri.BG42 ndi chitsulo china chotentha kwambiri chomwe chimakhala ndi kuuma kwabwino kwa kutentha kwa 300 ° C ndipo chimatchulidwa kawirikawiri chifukwa chimakhala ndi mphamvu zambiri zoteteza dzimbiri komanso sichikhoza kutopa komanso kuvala pa kutentha kwambiri.

Makhola otentha kwambiri amafunikanso ndipo amatha kuperekedwa muzinthu zapadera za polima kuphatikizapo PTFE, Polyimide, Polyamide-imide (PAI) ndi Polyether-ether-ketone (PEEK).Pakuti mkulu kutentha mafuta lubricated kachitidwe kubala osayenera angathenso chopangidwa kuchokera mkuwa, mkuwa kapena siliva yokutidwa zitsulo.

Zopaka ndi kutentha mankhwala

Zopaka zapamwamba ndi mankhwala opangira pamwamba angagwiritsidwe ntchito pazitsulo kuti athane ndi mikangano, kuteteza dzimbiri ndi kuchepetsa kutha, motero kumapangitsa kuti ntchito yobereka ikhale yabwino kwambiri.Mwachitsanzo, makhola achitsulo amatha kukhala ndi siliva kuti apititse patsogolo ntchito komanso kudalirika.Pankhani ya kulephera kwamafuta / njala, siliva-plating imagwira ntchito ngati mafuta olimba, kulola kuti kunyamula kupitirire kuthamanga kwakanthawi kochepa kapena mwadzidzidzi.

Kudalirika pa kutentha kochepa

Kumapeto ena a sikelo, kutentha kotsika kumatha kukhala kovuta kwa ma bearings wamba.

Kupaka mafuta

M'malo otentha kwambiri, mwachitsanzo, kupopera kwa cryogenic komwe kumatentha kudera la -190 ° C, zokometsera zamafuta zimakhala phula zomwe zimapangitsa kulephera.Mafuta olimba monga MOS2 kapena WS2 ndi abwino kuwongolera kudalirika.Kuphatikiza apo, pamapulogalamuwa, ma media omwe amapopedwa amatha kukhala ngati mafuta, chifukwa chake ma bearings ayenera kukonzedwa mwapadera kuti azigwira ntchito pazitentha zotsika izi pogwiritsa ntchito zida zomwe zimagwira ntchito bwino ndi media.

Zipangizo

Chinthu chimodzi chomwe chitha kugwiritsidwa ntchito kupititsa patsogolo moyo wotopa komanso kukana kuvala ndi SV30® - martensitic yolimba, nitrogen yambiri, chitsulo chosagwira dzimbiri.Mipira ya Ceramic imalimbikitsidwanso pamene ikupereka magwiridwe antchito apamwamba.Zomwe zimapangidwira zimatanthawuza kuti zimagwira ntchito bwino kwambiri m'malo osapaka mafuta, ndipo ndizoyenera kugwira ntchito modalirika pakatentha kwambiri.

Zinthu za khola ziyeneranso kusankhidwa kuti zisavale momwe zingathere ndipo zosankha zabwino apa zikuphatikiza PEEK, Polychlorotrifluoroethylene (PCTFE) ndi mapulasitiki a PAI.

Kutentha mankhwala

Mphete ziyenera kutenthedwa mwapadera kuti zikhazikike bwino pakatentha kwambiri.

Mapangidwe amkati

Chinthu chinanso chogwirira ntchito kumalo otentha kwambiri ndi kapangidwe kake ka mkati.Ma bearings amapangidwa ndi mulingo wa sewero la ma radial, koma kutentha kumachepetsa, zigawo zonyamula zimadutsana ndi kutentha ndipo kuchuluka kwa ma radial play kumachepetsedwa.Ngati mulingo wa sewero la ma radial utsikira ku ziro panthawi yogwira ntchito izi zipangitsa kulephera kubereka.Ma bearings omwe amapangidwira kuti azigwiritsidwa ntchito kutentha pang'ono ayenera kupangidwa ndi kusewera kwa ma radial pazipinda zotentha kuti alole mulingo wovomerezeka wamasewera opangira ma radial pa kutentha kotsika.

Kugwira ntchito ya vacuum

M'malo otsekemera kwambiri monga omwe amapezeka popanga zamagetsi, ma semiconductors ndi ma LCD, kupanikizika kumatha kukhala kotsika kuposa 10-7mbar.Ma bearing a vacuum apamwamba kwambiri nthawi zambiri amagwiritsidwa ntchito pazida zochitira zinthu m'malo opanga.Njira ina yogwiritsira ntchito vacuum ndi mapampu a turbomolecular (TMP) omwe amapanga vacuum yopangira malo.Mu ntchito yomaliza iyi, ma fani nthawi zambiri amafunikira kuti azigwira ntchito mwachangu.

Kupaka mafuta

Kupaka mafuta m'mikhalidwe imeneyi ndikofunikira.Pamalo otsekemera okwera chotere, mafuta opaka mafuta amasanduka nthunzi komanso amatuluka mpweya, ndipo kusowa kwa mafuta ofunikira kungayambitse kulephera.Choncho, mafuta apadera ayenera kugwiritsidwa ntchito.Pamalo otsekemera kwambiri (mpaka pafupifupi 10-7 mbar) mafuta a PFPE atha kugwiritsidwa ntchito chifukwa amakana kutulutsa mpweya.Pamalo otsekemera kwambiri (10-9mbar ndi pansi) mafuta olimba ndi zokutira ayenera kugwiritsidwa ntchito.

Kwa madera apakati a vacuum (ozungulira 10-2mbar), ndikukonzekera mosamala ndi kusankha mafuta apadera a vacuum, machitidwe omwe amapereka nthawi yayitali ya moyo wa maola oposa 40,000 (pafupifupi zaka 5) ogwiritsidwa ntchito mosalekeza, ndikugwira ntchito mofulumira kwambiri, akhoza zatheka.

Kukana dzimbiri

Ma bearings omwe amapangidwa kuti azigwiritsidwa ntchito pamalo ochita dzimbiri amayenera kukonzedwa mwapadera chifukwa amatha kukhala ndi ma acid, alkalis ndi madzi amchere pakati pa mankhwala ena owononga.

Zipangizo

Zipangizo ndizofunika kuziganizira m'malo owononga.Zitsulo zokhala ndi ziwiya zokhala ndi dzimbiri zimaonongeka mosavuta, zomwe zimapangitsa kulephera kubereka msanga.Pankhaniyi, mphete ya SV30 yokhala ndi mipira ya ceramic iyenera kuganiziridwa chifukwa imalimbana kwambiri ndi dzimbiri.M'malo mwake, kafukufuku wasonyeza kuti zinthu za SV30 zimatha kukhala nthawi yayitali kuposa zitsulo zina zosagwira dzimbiri pamalo opopera mchere.M'mayeso oyendetsedwa ndi kupopera mchere wa SV30 zitsulo zimangowonetsa zizindikiro zochepa za dzimbiri pambuyo pa maola 1,000 akuyesa kupopera mchere (onani chithunzi 1) ndi kukana kwa dzimbiri kwa SV30 kumawonekera bwino pa mphete zoyesera.Zida zapadera za mpira wa ceramic monga Zirconia ndi Silicon Carbide zitha kugwiritsidwanso ntchito kupititsa patsogolo kukana kwa chiwombankhanga kuzinthu zowononga.

Kupeza zambiri kuchokera ku zokometsera zama media

Malo ovuta omaliza ndi omwe amawagwiritsa ntchito pomwe media imagwira ntchito ngati mafuta, mwachitsanzo mafiriji, madzi, kapena madzimadzi amadzimadzi.Muzogwiritsira ntchito zonsezi ndizofunika kuziganizira kwambiri, ndipo SV30 - ceramic hybrid bearings nthawi zambiri zapezeka kuti zimapereka yankho lothandiza kwambiri komanso lodalirika.

Mapeto

Madera owopsa amabweretsa zovuta zambiri zogwirira ntchito kumayendedwe wamba, zomwe zimapangitsa kuti alephere msanga.M'mawonekedwe awa amayenera kukonzedwa mosamala kuti agwirizane ndi cholinga komanso kuti apereke magwiridwe antchito okhalitsa.Kuonetsetsa kudalirika mkulu wa zitsulo chisamaliro chapadera ayenera kulipidwa mafuta, zipangizo, zokutira pamwamba ndi kutentha mankhwala.
