Vim li cas kev ua tau zoo ntawm cov yas bearing zoo dua li ntawm cov hlau bearing

 

1. Kev loj hlob ntawm cov yas bearings

Tam sim no, feem ntau ntawm cov neeg siv khoom yog tseem txaus siab xaiv cov hlau bearing rau cov khoom siv. Tom qab tag nrho, thaum cov yas bearings tsis tau tsim, cov hlau bearings yeej ib txwm siv ua cov ntaub ntawv ib txwm muaj. Tab sis txog tam sim no, kev ua tau zoo ntawm cov yas bearings yuav zoo dua thiab zoo dua yav tom ntej.

2.Cov ntaub ntawv yas thiab cov txiaj ntsig

TTus nqi tsim khoom ntawm cov yas qis dua li ntawm cov hlau bearings, thiab ntau yam khoom siv yas yog nplua nuj zuj zus thiabsiv rau hauv ntau yam lag luam, cov ntaub ntawv yas feem ntauCov khoom siv no yog nylon, polytetrafluoroethylene, polyethylene thiab PEEK.

Lub cov kabmob yas is kev ua tau ntau yam, kev txuag nyiaj thiab kev huv. Muaj ntau yam khoom siv pheej yig rau ntau yam kev siv. Cov kabmob yas feem ntau yog ua los ntawm cov thermoplastic alloys nrog cov fiber matrix thiab cov roj nplua nyeem khov kho, uas muaj lub zog zoo heev thiab cov coefficient sib txhuam qis tas li.

3. Dab tsi yog qhov kev ua tau zoo ntawm cov yas bearings ?

(1) Kev siv roj los ntawm tus kheej

Cov yas's Cov yam ntxwv uas muaj nyob hauv, ua rau cov bearings ntub, txo qhov qeeb ntawm kev pib ua haujlwm thiab ua kom thaj chaw huv. Qhov me me ntawm cov bearings raug hnav thaum pib thiab ua lub luag haujlwm ntawm kev ntub cov bearings, tab sis qhov kev hloov pauv ntawm cov bearings nws tus kheej tuaj yeem tsis quav ntsej. Qhov no kuj ua rau cov bearings yas tsim nyog dua rau kev siv zaub mov, vim FDA txwv tsis pub siv cov roj nplua nyeem hauv cov tshuab tsim khoom noj. Tsis tas li ntawd, txawm hais tias cov hmoov av thiab lwm yam khoom me me yuav lo rau cov roj nplua nyeem thiab tsim ib txheej av, rau cov bearings yas, txhua yam khoom me me yuav tsuas yog nkag mus rau hauv cov bearings thiab yuav tsis cuam tshuam rau kev ua haujlwm.

(2) Kev ua haujlwm ntawm qhov kub qis thiab siab

Cov bearings yas tuaj yeem ua haujlwm tas li ntawm txhua qhov kub ntawm - 4° C thiab 260° C thiab tuaj yeem tiv taus qhov kub siab tshaj plaws txog li 600° F. Lub bushing yas tuaj yeem muaj zog npaum li lub bushing hlau, tab sis kev coj ua phab ntsa nyias nyias, feem ntau yog 0.0468 "- 0.0625" tuab. Cov phab ntsa nyias nyias muab cov cua sov zoo dua, ua rau muaj kev ua haujlwm ntau dua thiab txo qhov hnav. Tsis tas li ntawd, cov phab ntsa nyias nyias dua thiab tsis tshua muaj peev xwm hloov pauv, ua rau lawv haum rau cov ntawv thov uas muaj teeb meem hnyav.

(3) Kev ua tau zoo ntawm ib puag ncig

Vim yog qhov hnyav ntawm cov yas, cov yas bearings siv roj tsawg dua. Cov yas bearings tsis xav tau cov txheej ntxiv lossis cov khoom ntxiv kom tsim tau cov txiaj ntsig zoo ib yam li cov khoom hlau feem ntau ntxiv nrog cov khoom phom sij. Tsis tas li ntawd, kev tsim cov yas tsuas yog xav tau li 10-15% roj piv rau tib tus nqi ntawm txhuas lossis hlau.

(4) Tshuaj lom neeg tsis kam

Cov bearings yas feem ntau tiv taus ntau yam tshuaj lom neeg thiab cov khoom ntau dua li cov bearings hlau, thiab tiv taus khawb thiab hnav ntawm cov bearings hlau. Qhov no pab tswj lawv cov coefficient qis ntawm kev sib txhuam thiab txav mus los zoo nrog kev cuam tshuam tsawg kawg nkaus.

(5) Kev txij nkawm dawb bearing

Xaiv cov yas kom raug raws li qhov chaw siv, thiab cov kabmob tuaj yeem tiv taus xeb dhau sijhawm. Tom qab kev teeb tsa, cov kabmob yas muaj lub neej ua haujlwm ntev thiab tsis tas yuav hloov. Kev xeb tuaj yeem ua rau cov kabmob hlau khov rau hauv qhov chaw, ua rau lawv yuav luag tsis tuaj yeem tshem tawm yam tsis txiav lawv tawm. Cov kabmob yas yooj yim tshem tawm.

(6) Tus nqi qis ntawm cov yas

Ntau yam yas pheej yig dua li cov hlau. Yog li ntawd, cov yas bearings thiab cov yas bushings tuaj yeem txo cov nqi.
