Cov Khoom thiab Cov Kev Xav Tau Ntawm Bearing Steel (2)

Rolling bearing cov ntaub ntawv muaj xws li dov bearing cov ntaub ntawv thiab tawb, rivets thiab lwm yam khoom pab. Feem ntau ntawm dov bearings thiab lawv qhov chaw yog ua los ntawm cov hlau, thiab cov hlau siv rau dov bearings feem ntau yog siab carbon chromium steel thiab carburized steel. Nrog rau txoj kev loj hlob ntawm kev tshawb fawb niaj hnub thiab thev naus laus zis thiab kev siv cov dov bearings ntau ntxiv, cov kev xav tau ntawm cov bearings tau nce siab dua, xws li kev ua haujlwm siab, lub neej ntev thiab kev ntseeg siab. Rau qee lub hom phiaj tshwj xeeb, cov khoom siv bearings kuj yuav tsum muaj qhov kub thiab txias, tiv thaiv corrosion, tsis muaj hlau nplaum, ultra-low kub, hluav taws xob tiv thaiv thiab lwm yam khoom. Tsis tas li ntawd, cov khoom siv bearing kuj suav nrog cov khoom siv hlau, cov hlau tsis muaj hlau thiab cov khoom tsis yog hlau. Tsis tas li ntawd, bearings ua los ntawm cov khoom siv ceramic tau siv rau hauv locomotives, tsheb, subways, aviation, aerospace, tshuaj thiab lwm yam kev lag luam.

Cov khoom siv tseem ceeb ntawm dov bearings nyob ntawm qhov loj ntawm kev ua haujlwm ntawm cov kabmob. Txawm hais tias cov khoom siv los tsim cov yob bearings tsim nyog yuav muaj kev cuam tshuam zoo rau nws qhov kev ua tau zoo thiab lub neej. Feem ntau, lub ntsiab tsis ua hauj lwm ntawm dov bearings yog qaug zog spalling nyob rau hauv alternating kev ntxhov siab thiab poob ntawm bearing raug vim kev sib txhuam thiab hnav. Tsis tas li ntawd, kuj muaj cov kab nrib pleb, indentations, xeb thiab lwm yam uas ua rau kev puas tsuaj rau cov kabmob. Yog li ntawd, dov bearings yuav tsum muaj siab tsis kam rau cov yas deformation, tsis muaj kev sib txhuam thiab hnav, zoo rotational raug, zoo seem raug thiab stability, thiab ntev kev sib cuag qaug zog lub neej. Thiab ntau yam ntawm cov khoom no yog sib koom ua ke los ntawm cov khoom siv thiab cov txheej txheem kho cua sov. Txij li cov kev cai yooj yim ntawm dov bearings rau cov ntaub ntawv yog txiav txim siab los ntawm kev puas tsuaj ntawm cov bearings, cov ntaub ntawv uas yuav tsum tau los tsim rolling bearings yuav tsum muaj cov khoom nram qab no tom qab kev kho cua sov hauv cov txheej txheem tom qab:

c. Siab elastic txwv

Thaum cov kabmob dov ua haujlwm, vim qhov chaw sib cuag me me ntawm cov khoom siv dov thiab cov kev sib tw ntawm lub nplhaib, thaum cov kabmob yog nyob rau hauv kev thauj khoom, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej ntawm cov load loj, kev sib cuag ntawm qhov chaw sib cuag loj heev. Txhawm rau tiv thaiv qhov tshwm sim ntawm cov yas ntau dhau deformation nyob rau hauv kev sib cuag nrog kev ntxhov siab, qhov poob ntawm cov kabmob raug lossis qhov tshwm sim ntawm cov kab nrib pleb, nws yuav tsum muaj cov kabmob steel yuav tsum muaj kev txwv siab.

d. Tsim nyog hardness

Hardness yog ib qho tseem ceeb qhia ntawm dov bearings. Nws muaj kev sib raug zoo nrog cov khoom siv tiv thaiv qaug zog, hnav tsis kam, thiab elastic txwv, uas cuam tshuam ncaj qha rau lub neej ntawm cov kabmob dov. Lub hardness ntawm cov kabmob feem ntau yog txiav txim siab raws li qhov xwm txheej dav dav ntawm cov kabmob load bearing txoj kev thiab loj, bearing loj thiab phab ntsa thickness. Lub hardness ntawm cov hlau siv rau dov bearings yuav tsum tsim nyog, loj los yog me me heev yuav cuam tshuam rau lub neej kev pab cuam ntawm cov kabmob.

Raws li peb txhua tus paub, cov ntaub ntawv tsis ua haujlwm tseem ceeb ntawm dov bearings yog kev puas tsuaj rau kev qaug zog, thiab kev poob ntawm cov kabmob raug vim tsis zoo hnav tsis kam lossis qhov tsis ruaj khov; Yog hais tias cov bearing qhov chaw tsis muaj ib tug tej yam toughness, lawv yuav raug rau loj tej yam loads vim nkig puas. kev puas tsuaj rau cov kabmob. Yog li ntawd, qhov hardness ntawm cov kabmob yuav tsum tau txiav txim siab raws li qhov xwm txheej tshwj xeeb ntawm cov kabmob thiab txoj kev puas tsuaj. Rau qhov poob ntawm bearing raug vim qaug zog spalling los yog tsis zoo hnav tsis kam, siab dua hardness yuav tsum tau siv rau bearing qhov chaw; rau cov kabmob uas muaj kev poob siab loj (xws li dov mills: bearings, railway bearings thiab qee lub tsheb bearings, thiab lwm yam), nws yuav tsum raug txo kom tsim nyog. Hardness yog tsim nyog los txhim kho lub toughness ntawm cov kabmob.

e, ib qho kev cuam tshuam toughness

Ntau cov dov bearings yuav raug rau qee yam kev cuam tshuam thaum siv, yog li cov kabmob steel yuav tsum muaj qee yam toughness los xyuas kom meej tias cov kabmob tsis raug puas vim muaj kev cuam tshuam. Rau cov kabmob uas muaj kev cuam tshuam loj, xws li dov zeb bearings, railway bearings, thiab lwm yam, cov ntaub ntawv yuav tsum muaj kev cuam tshuam loj heev thiab tawg toughness. Xyuas kom meej tias cov bearings no muaj kev cuam tshuam zoo toughness.

f. Zoo dimension stability

Rolling bearings yog precision mechanical qhov chaw uas nws qhov tseeb yog ntsuas hauv microns. Thaum lub sij hawm ntev cia thiab siv, cov kabmob loj yuav hloov pauv vim muaj kev hloov pauv hauv cov qauv sab hauv lossis kev ntxhov siab, ua rau poob ntawm qhov tseeb ntawm cov kabmob. Yog li ntawd, txhawm rau kom ntseeg tau qhov tseeb qhov tseeb ntawm cov kabmob, cov kabmob steel yuav tsum muaj qhov ruaj khov zoo.

g, kev ua haujlwm zoo tiv thaiv xeb

Muaj ntau ntau cov txheej txheem rau dov bearings, thiab lub voj voog ntau lawm ntev. Qee qhov semi-tiav lossis tiav lawm yuav tsum tau khaws cia ntev ua ntej sib dhos. Yog li ntawd, cov khoom siv bearing yog feem ntau ua rau xeb thaum lub sijhawm tsim khoom lossis thaum lub sijhawm khaws cov khoom tiav, tshwj xeeb tshaj yog nyob rau hauv huab cua noo. Yog li ntawd, cov kabmob steel yuav tsum muaj cov xeb zoo.

h, kev ua haujlwm zoo

Nyob rau hauv cov txheej txheem ntawm dov bearing, nws cov khoom mus los ntawm ntau yam txias thiab kub ua hauj lwm txheej txheem. Qhov no yuav tsum tau hais tias cov kabmob steel yuav tsum muaj cov txheej txheem zoo, xws li txias thiab kub tsim cov khoom, txiav, sib tsoo kev ua tau zoo thiab kev kho cua sov, thiab lwm yam, kom tau raws li qhov xav tau ntawm cov khoom loj, kev ua haujlwm siab, tus nqi qis thiab siab. - zoo ntau lawm ntawm dov bearings.

Tsis tas li ntawd, rau cov bearings siv nyob rau hauv tshwj xeeb ua hauj lwm tej yam kev mob, nyob rau hauv tas li ntawd mus rau saum toj no-hais yooj yim yuav tsum tau, coj tshwj xeeb kev ua tau zoo yuav tsum tau muab tso rau pem hauv ntej rau cov hlau siv, xws li kub tsis kam, siab ceev kev ua tau zoo, corrosion kuj thiab anti-magnetic. kev ua tau zoo.
