1. 1 Kev txhuam thiab coj khoom
Rolling bearing lub neej muaj kev cuam tshuam loj heev los ntawm cov khoom siv ntawm cov kabmob, tshwj xeeb tshaj yog nyob rau thaj chaw hnyav. Txawm li cas los xij, vim tias muaj ntau qhov kev sib txhuam ntawm cov ntxuag cov kabmob, txoj kev sib txhuam yuav tsum hnav, thiab cov kabmob yuav tsis zoo thaum hnav nrog qee yam. Hnav tsis ua haujlwm yog ib qho ntawm cov qauv tseem ceeb ntawm dov kev ua haujlwm tsis ua haujlwm. Cov kev coj hnav ntawm Cr4Mo4V tau kawm txog. Nws ntseeg tau tias cov nplaim ntawm cov khoom siv nrog cov nplaum coj thiab nkees hnav yuav ua rau tawg ntawm nto; thiab qhov kev tsom xam tribological ntawm dov kev coj tus kheej WEC tsis ua hauj lwm tau suav tias yog cov khoom ntawm kev sib txhuam cov khoom siv, kev sib txhuam tshuab thiab qhov sib npaug ntawm tribochemical. Yog li no, kawm txog kev sib txhuam thiab coj ntawm cov khoom siv cov khoom, tshawb txog kev hnav lub tshuab ntawm cov khoom siv cov khoom, thiab nrhiav kev txo qhov hnav ntawm cov ntxuag cov kabmob los ntawm cov khoom siv ntawm kev saib yog ib qho ntawm cov qauv siv los txhim kho lub neej ntawm cov kabmob bearings.
1. 2 Tus Qauv Tsim (Tus Tsim Qauv Kev Tsim Kho)
Nrog rau daim ntawv thov dav ntawm cov dov bearings, tshwj xeeb tshaj yog nyob rau hauv cov mob hnyav, qhov siab dua yuav tsum tau muab tso rau ntawm tus qauv tsim ntawm dov bearings. Lub hom phiaj ntawm cov qauv siv log dov yuav tsum ua kom tau raws li cov ntawv thov, xws li SKF
Kev kub ceev lub kaum sib tw pob sib tw [12] tsim los ntawm lub tuam txhab tau hloov cov qauv tsim kom tau raws li qhov kev kub ceev (dm · n = 1. 05 × 106 mm · r / min): Txhim kho qhov profile ntawm cov channel saum npoo thiab hloov kev sib cuag Lub ces kaum txhim kho cov duab ntawm lub tawb lub hnab, thaum kawg txo qhov zawv zawg ntawm pob thiab cov channel saum npoo, txo lub hnab tshos qhov quab yuam, thiab yog li txo qhov kev sib txhuam ntawm lub tawb thiab pob, thiab thaum kawg txhim kho lub siab kev coj tus kheej uas ua tau raws li qhov yuav tsum tau ua. Tus qauv tsim ntawm dov dov ua tiav tau txais txiaj ntsig ntawm kev txo qis ntawm kev sib txhuam ntawm txhua qhov kev sib txhuam thaum ua tau raws li cov neeg siv khoom. Nws tuaj yeem pom tau tias daim ntawv thov ntawm tribology pab txhim kho qhov tsim ntawm dov bearings.
1. 3 Qhov Kev Kho Mob Kom Zoo thiab Cov Haujlwm Sib Txawv
Nrog rau kev txheeb xyuas sab hauv kev txheeb xyuas ntawm qhov tsis ua tiav ntawm cov dov bearings, qhov tsis ua haujlwm feem ntau tshwm sim saum npoo thiab chaw seem ntawm ferrule lossis dov keeb; ntxiv rau, hauv cov ntsiab lus ntawm kev txuag hluav taws xob thiab txo kev ua qias tuaj thoob ntiaj teb,
Rolling bearing deg kho tshuab tau tsim kho sai heev. Nws ntseeg tau tias lub tshuab kho saum npoo ntawm dov bearings yog lub neej tom ntej kev txhim kho. Tsis hais txog ntawm cov tswv yim kev kho deg saum npoo ib puag ncig xws li carburizing, nitriding, PVD thiab CVD, lossis tawm qhov chaw kho cov tshuab kev kho mob xws li ion implantation, kho laser saum npoo, kev hloov kho ultrasonic saum npoo, thiab lwm yam, kev soj ntsuam kev ua tau zoo, piv txwv li hnav tsis kam, Nws yog qhov yuav tsum ua kom dhau kev sib txhuam sim. Cuam tshuam ntawm N ion implantation ntawm cov hnav cov khoom ntawm 9Cr18 txheej txheej, cov nyhuv ntawm cov hlau ion cog rau ntawm cov khoom hnav ntawm Cr4Mo4V thiab hnav cov khoom ntawm M50 nto kho los ntawm ZnO txheej txheej tau tshawb xyuas. Kev kho deg nrog cov tshuaj tiv thaiv ntuj tau txo qis qhov kev sib txhuam. Los ntawm kev kawm txog cov khoom muaj nuj nqis ntawm cov txheej txheem kho saum npoo, kev ua haujlwm thiab kev puas tsuaj ntawm cov txheej txheem hloov tau tuaj yeem nkag tau, thiab cov txheej txheem kho saum npoo yog thaum kawg txhim kho, thiab cov kabmob ua haujlwm thiab lub neej tau zoo dua. Yog li no, kev txhim kho kev txhim kho tau dav siv hauv dov cov txheej txheem kev kho tshuab.
