Yog li cas hom bearings muaj?

Bearings yog ib qho ntawm feem ntau siv cov khoom siv tshuab, bearing kev sib hloov thiab reciprocating txav ntawm lub ncej, smoothing lub zog ntawm lub ncej thiab txhawb nws.Yog tias siv cov bearings, kev sib txhuam thiab hnav tuaj yeem txo.Ntawm qhov tod tes, yog tias qhov zoo ntawm cov kabmob tsis zoo, nws yuav ua rau lub tshuab tsis ua haujlwm, yog li cov kabmob raug suav tias yog ib qho ntawm cov khoom siv tseem ceeb.
Yog li cas hom bearings muaj?
Muaj ob hom kabmob loj: zawv zawg bearings thiab dov bearings.
Sliding bearing:
Cov zawv zawg kabmob feem ntau yog tsim los ntawm lub rooj zaum bearing thiab bearing bush.Nyob rau hauv zawv zawg bearings, lub ncej thiab cov kabmob nto yog nyob rau hauv kev sib cuag ncaj qha.Nws tuaj yeem tiv taus kev kub ceev thiab kev poob siab.Plain bearings yog siv nyob rau hauv lub cav ntawm tsheb, nkoj, thiab tshuab.
Nws yog cov roj zaj duab xis uas txhawb kev sib hloov.Cov roj zaj duab xis yog ib qho thinly kis tau roj zaj duab xis.Thaum cov roj kub nce los yog lub load hnyav heev, cov roj zaj duab xis yuav ua thinner, ua rau cov hlau sib cuag thiab hlawv.
Lwm cov haujlwm muaj xws li:
1. Lub load tso cai yog loj, kev co thiab suab nrov me me, thiab nws tuaj yeem khiav ntsiag to.
2. Los ntawm kev siv cov txheej txheem lubrication thiab kev saib xyuas, kev pabcuam lub neej tuaj yeem siv tau ib nrab.
Rolling bearing
Rolling bearings yog nruab nrog cov khoom los yog cov chais (cov kab puag ncig) kom txo tau kev sib txhuam.Rolling bearings muaj xws li: sib sib zog nqus groove pob bearings, angular contact pob bearings, tapered roller bearings, thrust bearings, thiab lwm yam.
Lwm cov haujlwm muaj xws li:
1. Tsawg pib kev sib txhuam.
2. Piv nrog zawv zawg bearings, muaj kev sib txhuam tsawg dua.
3. Txij li qhov loj thiab qhov tseeb yog tus qauv, nws yog ib qho yooj yim mus yuav.
Kev sib piv ntawm kev ua haujlwm ntawm ob lub bearings:
Kev sib piv kev ua tau zoo:
Kev paub ntxiv: kev paub yooj yim ntawm cov kua roj lubrication
Fluid lubrication yog hais txog lub xeev ntawm lubrication nyob rau hauv uas ob yog tag nrho sib cais los ntawm ib tug kua zaj duab xis.Ntawm qhov zawv zawg ncej, lub siab tsim los ntawm cov kua hauv cov kabmob thiab cov ncej sib txawv txhawb nqa lub nra ntawm cov kabmob.Qhov no yog hu ua kua zaj duab xis siab.Lubrication txo qhov hnav thiab kev sib txhuam los ntawm kev txav mus los.Thaum siv rau lub sijhawm ntev, cov roj lubricating yuav tsum tau ua.
Yuav kom suav tau, bearings yog ib qho ntawm feem ntau siv qhov chaw (tus qauv) hauv kev tsim kho tshuab.Kev siv cov bearings zoo tuaj yeem txhim kho cov khoom lag luam thiab txo cov nqi.Yog li ntawd, nws yog ib qho tseem ceeb tshwj xeeb rau kev paub txog kev paub txog bearings.
