Raws li ib qho tseem ceeb txuas ntawm lub tsheb ncua kev kawm ntawv, cov khoom xaiv ntawm shock absorber bearings ncaj qha cuam tshuam rau load-cov kabmob muaj peev xwm, hnav tsis kam, qaug zog tiv thaiv, thiab kev hloov pauv ib puag ncig, ua rau nws yog ib qho tseem ceeb hauv kev txiav txim siab cov khoom lag luam thiab kev pabcuam lub neej. Tau ntsib nrog ntau yam kev tsav tsheb thiab kev ua tau zoo, kev lag luam tau tsim ntau yam - cov khoom siv raws li cov hlau matrix composites, ntxiv los ntawm polymer thiab tshwj xeeb alloys. Kev xaiv cov khoom yuav tsum muaj qhov sib npaug ntawm cov khoom siv kho tshuab, txheej txheem ua tau, thiab tus nqi.
Hlau matrix composites dominate lub shock absorber bearing teb, nrog siab -carbon chromium bearing steel (xws li GCr15) yog siv dav tshaj plaws. Hom hlau no, tom qab lub tshuab nqus tsev degassing, precision forging, thiab ntau yam kev kho cua sov, ua tiav siab hardness (HRC60 thiab siab dua) thiab zoo heev tiv tauj lub zog qaug zog, zoo tiv thaiv cov khoom sib hloov uas tsim los ntawm qhov siab - zaus reciprocating motion ntawm lub shock absorber. Nws cov khoom sib xyaw ua ke ntawm cov carbide cuam tshuam inhibit qhov pib tawg thiab nthuav tawm, txhim kho kev hnav tsis kam. Hauv cov xwm txheej uas xav tau kev tiv thaiv corrosion siab, qhov saum npoo tuaj yeem ntxiv dag zog nrog nitriding lossis chrome plating kom ntev kev pab cuam lub neej nyob rau hauv qhov chaw ntub dej thiab ntsev tsuag. Cov ntaub ntawv hlau muab lub zog zoo dua thiab kev ntseeg siab, ua rau lawv haum rau hnyav- lub luag haujlwm, siab - nrawm, thiab cov xwm txheej nyuaj. Txawm li cas los xij, lawv qhov ceev dua yuav tsum tau txiav txim siab hauv qhov hnyav-sensitive applications.
High-molecular-polymers hnyav tau pom lawv daim ntawv thov nthuav dav hauv xyoo tas los no, tau tsav los ntawm kev xav tau kev sib sib zog nqus thiab txo suab nrov. Engineering plastics xws li hloov kho nylon (PA66+GF) thiab polyoxymethylene (POM), nrog rau lawv qhov ntom ntom (kwv yees li ib - thib xya ntawm cov hlau), tus kheej zoo heev -lubricating zog, thiab zoo vibration damping thiab suab absorption, yog siv nyob rau hauv auxiliary bearing Cheebtsam uas tsis muaj loads tsawg. Cov ntaub ntawv no muaj qhov coefficient qis dua ntawm kev sib txhuam ntau dua li cov hlau, txo cov suab nrov ntawm kev ua haujlwm thiab hnav ntawm qhov chaw mating. Lawv kuj tuaj yeem ua tau zoo dua rau cov tshuaj corrosion thiab tsim nyog rau cov av noo, acidic, thiab alkaline ib puag ncig. Txawm li cas los xij, cov polymers tsis tshua muaj kev tiv thaiv tshav kub thiab nkag mus, feem ntau yuav tsum tau siv cov iav fiber ntau ntxiv los yog sib ntxiv ntawm hnav- cov khoom siv tiv thaiv los txhim kho kev txwv kev ua haujlwm. Tsis tas li ntawd, kev ua haujlwm degradation tuaj yeem tshwm sim nyob rau hauv cov loads siab lossis ntev kub kub.
Rau cov xwm txheej hnyav, xws li hnyav- tsheb thauj mus los, siab - qhov chaw kub, lossis muaj kev cuam tshuam muaj zog, cov khoom siv alloy tshwj xeeb qhia tau zoo tshwj xeeb. Copper-raws li hmoov metallurgy bearings siv cov qauv ntxeem tau impregnated nrog lubricating roj kom ua tiav "tus kheej-lubrication," tswj kev ua haujlwm txawm tias tsis muaj roj thiab txo qhov kev pheej hmoo ntawm kev ua tsis tiav sai. Titanium alloys, nrog rau lawv cov ultra- muaj zog tshwj xeeb thiab zoo heev corrosion kuj, yog siv nyob rau hauv aerospace thiab lwm yam teb uas tsis tshua muaj siab yuav tsum tau rau qhov hnyav thiab kev ntseeg tau. Txawm hais tias cov ntaub ntawv no kim dua los tsim, lawv muaj kev ua tau zoo uas nyuaj rau cov hlau thiab polymers kom haum rau hauv cov xwm txheej tshwj xeeb.
Hauv kev xaiv cov khoom siv tiag tiag, kev ntsuam xyuas yuav tsum tau ua raws li cov ntsuas ntsuas xws li kev ntsuas kev thauj khoom, kev khiav hauj lwm ceev, ambient kub, av noo, thiab qib corrosion, ua ke nrog kev loj hlob ntawm cov txheej txheem ntau lawm thiab nyiaj txiag muaj peev xwm. Siab - carbon chromium bearing steel yog nyiam rau cov tsheb dav hlau kom tau raws li lub zog thiab kev ua neej nyob; cov ntaub ntawv polymer tuaj yeem txiav txim siab rau lub tsheb teeb pom kev hauv nroog lossis lub zog tshiab tsheb kom txo qis qhov tsis muaj zog thiab suab nrov; hmoov metallurgy los yog titanium alloy kev daws teeb meem tuaj yeem qhia tau rau cov tsheb tshwj xeeb lossis cov cuab yeej siv hauv qhov chaw huab cua. Nyob rau hauv lub neej yav tom ntej, nrog rau kev nce qib ntawm cov khoom siv thev naus laus zis, cov khoom siv tshiab ua ke nrog lub teeb yuag, lub zog siab, kev tiv thaiv corrosion, thiab kev saib xyuas ntse yuav tsum qhib txoj hauv kev tshiab rau kev txhim kho kev ua haujlwm ntawm kev poob siab absorber bearings.
