Amaqhinga okukhetha kunye nokufaka isicelo see-Rolling Bearings kwiimeko ezikhethekileyo zokusebenza

 

Kwiinkqubo zoshishino zanamhlanje, ukusetyenziswaiibheringi eziqengqelekayokudala yanda ngaphaya kwezicelo zothumelo lwezixhobo eziqhelekileyo, yanda yaya kwiimeko zokusebenza ezikhethekileyo ezifana namaqondo obushushu aphezulu naphantsi, imithwalo ephezulu, ukugqwala, i-vacuum, kunye nokungcangcazela okukhulu. Iibheringi ezisemgangathweni zihlala zisokola ukuhlangabezana nezi mfuno zokusebenza zigqithisileyo, nto leyo ebangela ukuphuculwa okucwangcisiweyo kwindlela izinto ezisebenza ngayo, uyilo lwesakhiwo, iteknoloji yokuthambisa, kunye nezisombululo zokutywina ukuze kufunyanwe inkxaso ethembekileyo.

 

Ubushushu obuphezuluIindawo ezingqongileyo zixhaphakile kwi-metallurgy, kwimveliso yeglasi, nakwi-turbomachinery, apho iibheringi kufuneka zisebenze ngokuqhubekayo ngaphezu kwama-200°C. Phantsi kwezi meko, umngcipheko wokuthamba kwentsimbi eqhelekileyo yokuthwala uyanda, kwaye iikheyiji zisengozini yokuwohloka. Izisombululo zihlala zisebenzisa intsimbi efudumeleyo enobushushu obuphezulu (njenge-SUJ2-HT), intsimbi eqinileyo (njenge-JIS-SCM420H), okanye ii-alloys ezimelana nobushushu (njenge-M50 kunye ne-Inconel 718), zidityaniswe nezinto eziqengqelekayo ze-ceramic (Si₃N₄) ukunciphisa ukwanda kobushushu kunye nobunzima. Kwi-lubrication, i-lubrication coatings ephezulu yokusebenza (njenge-MoS₂ kunye ne-DLC) okanye ii-greases ezinobushushu obuphezulu zihlala zisetyenziswa. Kwezinye iimeko, iinkqubo zokupholisa ukuhamba kwe-oyile-umoya ziyasetyenziswa. Kwiindawo ezi-cryogenic okanye ezi-cryogenic, njengeepompo zegesi yendalo ezinyibilikisiweyo (LNG) kunye neenkqubo ze-spacecraft propulsion, ukubhitya kwezinto kunye nokuqina kwe-lubrication yimingeni emikhulu. Iibheringi zihlala zenziwe ngentsimbi engagqwaliyo ye-austenitic (njenge-AISI 440C ephathwe nge-cryogenically) okanye ii-alloys ezisekelwe kwi-nickel, ezithanjiswe nge-low-viscosity ester oils okanye ii-perfluoropolyether (PFPE) lubricants ukuqinisekisa ukusebenza kakuhle nokuba kumaqondo obushushu angaphantsi kwe-196°C.

 

Kwiindawo ezinzima nezinobunzima, ezinje ngoomatshini bemigodi, iirolling mills, kunye neebhokisi ezinkulu zegiya, iibheringi zifuna ukuqina okuphezulu kakhulu kunye nexesha elide lokudinwa.Iibheringi zerola ezisilinda ezimbini, iibheringi zerola ezinemigca emine ezithambileyookanyeiibheringi zerola ezingqukuvazisetyenziswa rhoqo kwezi zicelo. Umthamo womthwalo uphuculwa ngokusebenzisa iiprofayili zerola ezilungisiweyo, ulawulo lomthwalo wangaphambi kokulayisha, kunye nonyango lokuphucula umphezulu olufana nokufaka i-carbonitriding.

 

Kwiindawo ezirhabaxa, ezifana neempompo zeekhemikhali kunye nezixhobo zokucoca amanzi olwandle, iibheringi zentsimbi eziqhelekileyo zichaphazeleka lula kukugqwala. Izisombululo ziquka iibheringi zentsimbi engagqwaliyo (ezifana ne-X65Cr13 kunye ne-1.4122),iibheringi ze-ceramic hybridokanye izinto zokugquma ezingamelani nokugqwala (ezifana ne-electrophoresis okanye i-PVD coating) kwizangqa zangaphakathi nezangaphandle, zidityaniswe nezakhiwo zokutywina ezivalekileyo ngokupheleleyo (ezifana nezitywino zerabha ezidibeneyo okanye izitywino ze-labyrinth zesinyithi) ukuze kwahlulwe ukungena kwemidiya.

 

Ngaphezu koko, kwizicelo zesantya esiphezulu ezifana neespindle zombane ezikhawulezayo kunye neecompressor ze-centrifugal, iibheringi kufuneka zilinganisele ukungqubana okuphantsi, ukuveliswa kobushushu obuphantsi, kunye nokuzinza okuguquguqukayo.Iibheringi zebhola zoqhagamshelwano ze-angular(ingakumbi ezo zineebhola zeseramikhi ezifakwe kwangaphambili) ziye zaba lukhetho oluqhelekileyo, zidibene netekhnoloji yokuthambisa ngeoyile okanye yokuphola ngesitshizi ukulawula ngempumelelo ukunyuka kobushushu.

 

Kubalulekile ukuqaphela ukuba ukukhethwa kweebheringi kwiimeko zokusebenza ezikhethekileyo akunakuxhomekeka kuphela kwiiparameters ezisemgangathweni; uvavanyo olucwangcisiweyo kufuneka lwenziwe ngokusekelwe kwiimeko zokusebenza zokwenyani, kubandakanya i-load spectrum, utshintsho lwesantya, ukulingana kofakelo, iimpazamo zokulungelelanisa, kunye namaxesha okugcinwa. Inani elikhulayo lezicelo liyamkela ingcamango "yobunjineli beenkqubo zeebheringi," apho abavelisi banikezela ngoyilo olulungiselelwe wena, ukujonga imeko edibeneyo, kunye neenkonzo zomjikelo wobomi obupheleleyo.

 

Njengoko izixhobo zoshishino ziphuhlisa ukusebenza kakuhle, ixesha elide kunye nokugcinwa okuncinci, ii-rolling bearings zeemeko zokusebenza ezikhethekileyo ziyaguquka zibe zizinto ezidityanisiweyo, izakhiwo ezikrelekrele kunye nokuthambisa okudibeneyo, okubonelela ngokuqhubekayo ngenkxaso ephambili yokusebenza okuzinzileyo kwezixhobo kwiindawo ezixineneyo.
