Insimbi yokuthwala engagqwali iyisigaba esikhethekile se-alloy esenzelwe ukuhlanganisa izakhiwo ezithwala umthwalo, ezingagugi zezinsimbi zokuthwala zendabuko kanye nokumelana okuthuthukisiwe kwe-oxidation kanye nemidiya egqwalayo. Njengoba izimboni zicindezela imishini ezindaweni eziqinile—amandla asolwandle, ukucubungula ukudla, ezokwelapha, amakhemikhali, kanye namandla avuselelekayo—ama-bearings ajwayelekile e-chromium anekhabhoni ephezulu (isb., i-SAE 52100) awasanele. Ama-bearings amelana nokugqwala andisa impilo yesevisi, anciphisa isikhathi sokungasebenzi kanye nokugcinwa, futhi avumela ukusebenza okuthembekile lapho kukhona umswakama, usawoti, ama-acid noma izinto zokuhlanza. Lokhu kubuka konke komkhiqizo kufingqa izinhlobo eziyinhloko zama-bearings amelana nokugqwala, intuthuko yakamuva yentuthuko, kanye nezinzuzo ezibalulekile ezenza kube ukukhetha okuthandwayo kwezicelo ezidinga kakhulu.
Izinhlobo zezinsimbi ezithwalayo ezingagqwali ziwela ezinhlotsheni eziningana, ngayinye ilungiselelwe ukulinganisela kobulukhuni, ukuqina kanye nokumelana nemvelo. Izinsimbi ze-Martensitic stainless bearing (isibonelo i-AISI 440C kanye ne-X46Cr13 ehlobene) zisetshenziswa kabanzi lapho kudingeka khona ubulukhuni obuphezulu kanye nokumelana okuhle nokugqwala; zingaphathwa ngokushisa ukuze kufezwe impilo yokukhathala ephezulu. Izinsimbi ze-stainless eziqinisa imvula (17-4PH, 15-5PH) zinikeza inhlanganisela enamandla yamandla aphezulu, ukuqina kanye nokumelana nokugqwala ngemva kokuqina, ezifanelekela izindiza kanye nama-bearing ezimboni. Izinsimbi ze-Austenitic stainless (isibonelo, 316L, 304) zinikeza ukumelana okuhle kakhulu nokugqwala futhi zisetshenziswa lapho ukusebenza kokugqwala kubaluleke kakhulu, yize zivame ukunikeza ubulukhuni obuphansi obungafinyeleleka. Ama-alloy akhulayo ane-nitrogen ephezulu kanye nama-alloy akhethekile (i-Cronidur 30 kanye nezinsimbi ezifanayo eziqiniswe yi-nitrogen) anikeza ukusebenza okuthuthukisiwe kokukhathala kanye nokugqwala. Izinsimbi ze-Powder metallurgy (PM) stainless bearing zinikeza ukuhlanzeka okuphezulu, ukulawulwa kwesakhiwo esincane kanye nokufana kwezicelo ezibalulekile.
Intuthuko yezinsimbi ezithwala ama-bearing ezingagqwali iye yashesha ngokuklama i-alloy, ukuncibilikisa nokucubungula izinto ezintsha, kanye nobuchwepheshe bobunjiniyela bendawo.Ukuncibilika kwe-vacuum induction yesimanje (VIM), ukuncibilika kwe-electroslag (ESR) kanye ne-powder metallurgy kunciphisa ukufakwa futhi kwandise ukuhlanzeka, okuthuthukisa ngqo impilo yokukhathala. Ukuhlanganiswa kwe-nitrogen ephezulu kanye nokuqukethwe kwe-chromium, i-molybdenum kanye ne-nickel okulinganiswe ngokucophelela kuvumela amafilimu aqinile angasebenzi kanye nokumelana okungcono kwe-pitting. Ukwelashwa ngokushisa kanye nokucubungula kwe-cryogenic kulungisa izakhiwo ezincane ze-martensitic ukuze kube nokuqina okulinganayo kanye nokuqina kobukhulu. Ngasohlangothini lobuso, i-plasma nitriding esezingeni eliphansi lokushisa, izembozo ze-PVD/DLC, kanye nama-liners amancane e-ceramic noma e-polymer kungathuthukisa ukumelana nokuguguleka ngaphandle kokubeka engcupheni ukuvikelwa kokugqwala. Umklamo we-alloy wokubala kanye nokufaneleka okusheshayo kwesivinini sokuhlola ukugqwala nokukhathala kwezinhlelo zokusebenza ezintsha.
Izinzuzo kanye nezici zokusebenza kwezinsimbi ezithwalayo ezingagqwali zihumusha zibe izinzuzo ezibonakalayo emishinini nasezinhlelweni. Lezi zinto zinciphisa ingozi yokuqhekeka kwe-hydrogen kanye nokuqhekeka ezindaweni ezinosawoti noma ezinolaka lwamakhemikhali, kuyilapho zigcina amandla okuxhumana kanye nokumelana nokuguguleka okudingekayo ezintweni ezigingqikayo kanye nokugijima. Ukunakekelwa okuphansi kanye nokugcotshwa okuncane noma ukushintshwa okuvamile kunciphisa izindleko zomjikelezo wokuphila—Okubalulekile ekufakweni kwasogwini lolwandle, ekucubunguleni ukudla kanye nasezikhungweni zezokwelapha. Amabanga amaningi ahambisana nezindinganiso zokuhlanzeka (isb., i-FDA/USP) ngemva kokuqedwa kahle, okwenza zifaneleke ukusetshenziswa kwenhlanzeko. Ngaphezu kwalokho, ukutholakala kokwelashwa kokushisa okwenziwe ngokwezifiso, ukuqedwa okunembile kanye nezingxenye ze-PM eziseduze nokwakheka kwenethi kwenza abaklami bakwazi ukwenza ngcono ama-bearings ukuze kube nesisindo, umsindo, kanye nokusebenza kahle ngenkathi befinyeza imijikelezo yokuhlanganisa.
Ngamafuphi, izinsimbi ezithwalayo ezingagqwali zihlanganisa ukusungula izinto ezintsha kanye nokucubungula kwesimanje ukuze zilethe ama-bearings athembekile, ahlala isikhathi eside asebenza lapho izinsimbi zendabuko zehluleka khona. Izinzuzo zazo eziyinhloko—ukumelana nokugqwala okuthuthukisiwe, ubulukhuni obuqhubekayo kanye namandla okukhathala, ukugcinwa okuncishisiwe, kanye nokusebenza ezindaweni ezilawulwayo nezinzima—Zenze zibe ukukhetha okukhangayo konjiniyela kanye nochwepheshe bokuthenga abafuna ukuthembeka kanye nezindleko eziphansi zobunikazi. Khetha izixazululo zethu zensimbi ezithwalayo ezingagqwali ukuze ukhethe izinto ezingochwepheshe, ukukhiqiza ngokunemba, kanye nokwenza ngokwezifiso okuphendulayo.
