Txheej Txheem Thiab Cov ntsiab lus tseem ceeb ntawm Kev Ua Stainless Hlau Bearings

Cov hlau muaj cov carbide complex (Fe, Cr) 7C3, uas yaj hauv austenite maj mam thaum rhuab. Lub caij no, cov hlau tsis zoo thermal conductivity, yog li lub forging cua sov ceev yuav tsum qeeb. Yog tias cov cua kub kub siab dhau los yog lub sij hawm nyob hauv qhov kub thiab txias yog qhov ntev heev, nws yog ib qho yooj yim los tsim cov menyuam ntxaib thiab rhuav tshem cov kev ua haujlwm ntawm cov hlau. Thiab vim tias cov hlau hardenability zoo dua thiab tsis zoo thermal conductivity, qhov txias tom qab forging yuav tsum tau qeeb, txwv tsis pub nws yooj yim tawg. Yog hais tias qhov kub ntawm forging yog siab dhau lawm, lub network carbide yog ib qho yooj yim los tsim, thiab coarse network carbide qauv yuav tsis raug tshem tawm nyob rau hauv lub neej yav tom ntej annealing txheej txheem. Cov khoom siv muaj kev ua haujlwm siab deformation, tsis tshua muaj plasticity thiab tsis zoo forging kev ua haujlwm ntawm qhov kub thiab txias, yog li nws muaj cov kev cai tshwj xeeb rau cov khoom siv thiab cov qauv ntawm cov tuag.
Txhawm rau ntsuas cov suab nrov ntawm cov bearings zoo dua, qhov kev vibration qhov tseem ceeb ntawm peb cov ntsiab lus tsis sib xws nyob rau hauv pem hauv ntej thiab nraub qaum ntawm txhua pawg bearings raug ntsuas hauv qhov ntsuas qhov tseeb, thiab qhov ntsuas qhov loj dua yog coj los ua tus nqi vibration zoo ntawm bearings.
(1) Tsawg suab nrov roj tuaj yeem txo qhov kev vibration thiab suab nrov ntawm bearings. Tom qab cov roj txhaj tshuaj, 100 feem pua ​​​​ua tau raws li qhov yuav tsum tau ua ntawm Z2 pawg (40 dB), 98 feem pua ​​​​ua tau raws li qhov yuav tsum tau ua ntawm Z3 pawg (38 dB), thiab cov khoom lag luam muaj qhov tseeb tshwj xeeb. Raws li kev cuam tshuam ntawm qee yam tsis muaj xws li tshuab cuab yeej ruaj ntseg, tsis sib xws ntawm kev sib tsoo log thiab sib tsoo log hnav, tsis zoo ntawm cov roj pob zeb thiab roj pob zeb hloov thiab hnav khaub ncaws zoo nyob rau hauv cov txheej txheem ntawm channel superfinishing, tag nrho cov txheej txheem muaj qee qhov hloov pauv thaum nws ua tau raws li qhov yuav tsum tau ua ntawm kev ua haujlwm raug.
(2) Thaum lub sij hawm sim, nws tau pom tias qhov kev vibration nqi ntawm 5 teev ntawm bearings nyob rau hauv ib leeg-sab xeem yog tus siab heev, thiab cov roj tau ntxuav tawm. Tom qab disassembly, nws tau pom tias ib sab ntawm cov channel tsis zoo superfinishing zoo thiab sab laug sib tsoo log. Qhov no qhia tau hais tias muaj qee qhov sib txawv ntawm qhov chaw viav vias ntawm cov roj pob zeb thiab qhov chaw curvature ntawm qhov zawj tom qab sib tsoo, uas cuam tshuam rau qhov chaw machining zoo ntawm qhov zawj. Raws li lub suab nrov nrov ntawm tus neeg hais lus, muaj 5 teeb pom kev txawv txav. Kev soj ntsuam cov roj nyob hauv, nws pom tias muaj kev nkag mus rau lub cev txawv teb chaws, thiab qhov zoo tshaj plaws ntawm cov channel tsis siab.
(3) 2000 teeb ntawm 6204E tau sim ua nrog cov txheej txheem tshiab, thiab qhov kawg kev vibration xeem tau txheeb xyuas qhov ua tau thiab kev ua tau zoo ntawm cov txheej txheem no, uas tau tsim cov kev paub zoo tshaj plaws rau kev tsim cov suab nrov qis.
(4) Txhim kho qhov tseeb ntawm qhov kawg ntawm lub ntsej muag thiab sab nraud txoj kab uas hla, muab cov txheej txheem zoo siv rau kev sib tsoo thiab kev ua tiav ntawm cov kabmob zawj, thiab pab txhawb kev ua haujlwm ntawm qhov zoo ntawm qhov zawj. Qhov kev vibration thiab suab nrov ntawm cov bearings tuaj yeem txo tau zoo los ntawm kev kho cov txheej txheem tsis zoo ntawm qhov zawj superfinishing los tsim cov kab txaij zoo nkauj thiab zoo nkauj ntawm qhov chaw.
(5) Nws tseem yog ib qho kev ntsuas zoo los txo cov kabmob vibration thiab suab nrov los txhim kho kev sib dhos zoo ntawm cov kabmob, nruj me ntsis siv cov txheej txheem tshwj xeeb thiab tshem tawm cov pob ntawm qhov chaw ua haujlwm ntawm cov kabmob.
