Linear bearing seals: hom, kev xaiv thiab kev siv
Cov ntsaws ruaj ruaj uas siv rau kev ncig cov kab bearings muaj ob txoj haujlwm-tiv thaiv kev sib kis thiab tswj cov roj lubrication-kom ntseeg tau tias lub kaw lus ua haujlwm ib txwm tsis hnav ntxov lossis tsis ua haujlwm. Txij li thaum sealing yog ib qho tseem ceeb rau linear bearing systems, manufacturers muab ntau yam sealing designs thiab cov ntaub ntawv kom tau raws li ntau yam kev siv thiab ib puag ncig.
Standard linear bearing seals
Feem ntau cov tuam ntxhab ntawm cov ntawv qhia recirculating linear muab cov ntsaws ruaj ruaj hauv ib lossis ob daim di ncauj. Cov ntsaws ruaj ruaj no tsim ib txoj kab txhim khu kev qha nrog cov kev taw qhia kev tsheb nqaj hlau, uas tuaj yeem tiv thaiv kev nkag mus ntawm cov khoom zoo thiab cov kua dej.
Muab ob npaug rau daim di ncauj muab ob qho kev cuam tshuam ntawm ib puag ncig sab nraud thiab cov khoom siv sab hauv ntawm cov kabmob, thiab feem ntau yog siv rau cov plua plav zoo heev (xws li ceramic lossis iav) thiab tshuaj lom neeg. Qee cov tuam txhab lag luam kuj tseem muab peb lub di ncauj foob ua cov khoom siv xaiv.
Thaum cov khoom sib kis muaj xws li cov khib nyiab loj thiab ntxhib (xws li hlau lossis ntoo chips lossis vuam slag) uas tuaj yeem ua rau lub ntsej muag foob, cov hlau nplaum tuaj yeem siv ntxiv rau cov qauv di ncauj. Hlau scrapers tawm ntawm qhov sib txawv me me ntawm lub foob thiab cov kev taw qhia kev tsheb ciav hlau, tab sis lawv tuaj yeem so lossis khawb cov khib nyiab loj los ntawm cov kev taw qhia rail zoo heev. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias vim tias lawv tsis sib cuag, cov hlau squeegees feem ntau tsis haum rau kev siv ib leeg yam tsis muaj kev xaiv sealing ntxiv.
Hlau ntsaws ruaj ruaj los yog scrapers yog siv ua ke nrog cov txheej txheem sealing los tiv thaiv cov kab mob loj dua xws li ntoo lossis hlau chips.
Feem ntau cov kab rov tav cov kabmob tsim muaj xws li sab hauv (qee zaum hu ua universal) cov ntsaws ruaj ruaj kom tsis txhob muaj cov kab mob sib kis los ntawm kev sib tsoo pem hauv ntej los yog tuaj yeem sau rau hauv lossis ib ncig ntawm lub tsheb ciav hlau mounting qhov.
Thaum peb xav txog linear bearing seals, peb feem ntau xav txog cov ntsaws ruaj ruaj pem hauv ntej nyob rau ntawm ob qhov kawg ntawm cov kabmob vaj tse. Tab sis feem ntau recirculating linear bearings kuj suav nrog cov ntsaws ruaj ruaj sab (tseem hu ua longitudinal lossis transverse seals) raws li cov qauv txheem. Cov no tuaj yeem tiv thaiv kom tsis txhob muaj kab mob nkag los hauv qab no, nyob rau sab ntawm cov kabmob vaj tse - tshwj xeeb tshaj yog thaum cov khoom siv tau nruab rau ntawm sab, ntsug lossis rov qab. Txawm li cas los xij, thaum lub foob sab nraud muab ib txheej ntxiv ntawm kev tiv thaiv, lub foob pem hauv ntej feem ntau ua haujlwm feem ntau hauv kev tiv thaiv kev nkag mus ntawm cov kab mob.
Nco ntsoov, qhov ntau lub foob nyob rau hauv kev sib cuag nrog lub khiav nto, lub zog ntau yuav tsum tau kov yeej kev sib txhuam ntawm lub foob. Qhov kev sib txhuam ntxiv no cuam tshuam qhov loj thiab xaiv ntawm cov khoom siv tsav tsheb. Cov chaw tsim khoom feem ntau tshaj tawm (lossis tuaj yeem muab tau) tus nqi ntawm lub zog yuav tsum tau kov yeej kev sib txhuam los ntawm lub foob.
Lub foob tsim kev sib txhuam ntawm lub rooj zaum bearing thiab cov kev taw qhia rail, yog li ua kom lub zog yuav tsum tau txav lub rooj zaum bearing. Qhov kev sib cuag ntau dua, qhov kev sib txhuam ntau dua. Qhia ntawm no yog kev sib txhuam qis, ib daim di ncauj thiab ob daim di ncauj
Txawm hais tias nws raug pom zoo kom siv cov ntsaws ruaj ruaj rau cov ntawv qhia tshwj xeeb thiab cov kab ntawv qhia, vim lawv qhov tseem ceeb hauv kev tswj kom zoo lubrication, round-axis linear guides thiab cam roller guides tuaj yeem ua haujlwm yam tsis muaj cov ntsaws ruaj ruaj. Sliding bearing linear guides feem ntau yog siv tsis muaj cov ntsaws ruaj ruaj, tshwj tsis yog ib puag ncig muaj cov pa phem.
