Muaj xya yam uas yuav tsum tau xav txog hauv kev xaiv cov bearings.
Txhua hom dov bearings muaj cov yam ntxwv sib txawv thiab tsim nyog rau kev siv sib txawv ntawm txhua yam ntawm cov tshuab.
Feem ntau, thrust bearing thiab angular contact bearing yog siv thaum bearing thrust load. Kev siv ceev ceev feem ntau yog siv pob bearings; Thaum bearing hnyav radial load, cov menyuam bearings yog siv.
1. Qhov chaw thiab txoj hauj lwm ntawm lub tshuab nyob ntawm cov kabmob
Hauv kev tsim kho tshuab, qhov loj ntawm cov ncej feem ntau txiav txim siab ua ntej, thiab tom qab ntawd cov kabmob dov raug xaiv raws li qhov loj ntawm cov ncej. Feem ntau qhov kev xaiv me me ntawm pob bearings, qhov loj ncej xaiv ntawm cov menyuam bearings. Txawm li cas los xij, thaum cov kabmob raug txwv nyob rau hauv cov kev taw qhia ntawm txoj kab uas hla ntawm lub tshuab, koob rau cov menyuam bearings, ultra-light, thiab ultra-light series ntawm pob lossis cov menyuam bearings raug xaiv; Thaum cov kabmob raug txwv nyob rau hauv txoj haujlwm axial ntawm lub tshuab, nqaim lossis ntxiv-nqaim ntawm pob lossis cov menyuam bearings tuaj yeem xaiv.
2. Qhov loj me, kev taw qhia, thiab qhov xwm txheej ntawm cov khoom thauj ntawm cov kabmob
Load yog qhov tseem ceeb tshaj plaws hauv kev xaiv cov bearings. Cov menyuam bearings yog siv los tiv thaiv hnyav dua, pob bearings yog siv los tiv thaiv kev sib zog los yog nruab nrab, thiab bearings ua los ntawm carburized carbon steel los yog bainitic quenching tuaj yeem tiv taus kev cuam tshuam thiab kev vibration loads.
Nyob rau hauv cov nqe lus ntawm kev taw qhia ntawm load, thaum bearing ntshiab radial load, sib sib zog nqus groove pob bearings, cylindrical roller bearings, los yog rab koob rau cov menyuam bearings yuav siv tau. Thaum bearing ib tug me me ntshiab axial load, thrust pob bearing tuaj yeem xaiv tau; Thaum bearing ib tug loj ntshiab axial load, thrust roller bearing yuav siv tau. Thaum lub bearing bears radial thiab axial ua ke load, ib qho kev sib cuag pob bearing lossis tapered roller bearing feem ntau yog siv.
3. Self-aligning kev ua tau zoo ntawm bearings
Thaum txoj kab nruab nrab ntawm cov ncej sib txawv ntawm cov kab nruab nrab ntawm lub rooj zaum bearing, muaj qhov yuam kev ntawm lub kaum sab xis, los yog lub rigidity ntawm lub ncej yog me me vim yog qhov loj ntawm qhov kev ncua deb ntawm ob qhov kev txhawb nqa ntawm lub ncej, thiab nws yog ib qho yooj yim. yuav khoov lossis qaij los ntawm kev quab yuam, tus kheej-aligning pob lossis tus kheej-aligning rau cov menyuam bearings nrog kev ua tau zoo ntawm tus kheej tuaj yeem xaiv tau, nrog rau cov pob bearings sab nraud. Cov kabmob no tuaj yeem ua haujlwm ib txwm ua thaum lub ncej me ntsis qaij lossis khoov.
Qhov zoo ntawm bearing self-aligning kev ua tau zoo muaj feem xyuam rau qhov tso cai sib txawv coaxiality. Qhov ntau dua tus nqi ntawm kev sib txawv coaxiality, qhov zoo dua qhov kev ua tau zoo ntawm tus kheej.
4. Rigidity ntawm bearings
Lub rigidity ntawm cov kabmob yog hais txog qhov loj ntawm lub zog xav tau los ntawm cov kabmob los tsim cov deformation ntawm chav tsev. Rolling bearing elastic deformation yog qhov me me, hauv cov tshuab feem ntau tsis tuaj yeem xav txog, tab sis hauv qee lub tshuab, xws li tshuab cuab yeej spindle, bearing rigidity yog ib qho tseem ceeb, feem ntau yuav tsum xaiv cylindrical thiab tapered roller bearings. Vim hais tias ob hom bearings nyob rau hauv load, lub dov lub cev thiab raceway muaj nyob rau hauv point kev sib cuag, lub rigidity yog tsis zoo.
Tsis tas li ntawd, txhua yam ntawm cov bearings tuaj yeem raug pretightened los ua kom cov rigidity ntawm kev txhawb nqa. Xws li angular contact pob bearings thiab tapered roller bearings, txhawm rau tiv thaiv kev vibration ntawm lub ncej, ua kom lub zog ntawm kev txhawb nqa, feem ntau hauv kev teeb tsa ntawm qee qhov ntawm axial quab yuam yog thov ua ntej, kom lawv sib sib zog nqus. . Tab sis lub preload tsis tuaj yeem loj dhau, txwv tsis pub nws yuav ua rau muaj kev sib txhuam ntawm kev sib txhuam, nce qhov kub thiab txias, cuam tshuam rau kev pab cuam lub neej ntawm bearings.
5. Ceev ntawm bearings
Txhua tus qauv bearing muaj nws tus kheej txwv ceev, uas yog txiav txim los ntawm lub cev yam ntxwv xws li loj, hom thiab qauv. Tshaj qhov kev txwv no yuav ua rau cov kabmob kub nce, lubricant kom qhuav, thiab ua rau cov kabmob daig. Kev xyaum tau ua pov thawj tias nws yog qhov zoo dua los ua haujlwm nyob rau hauv cov xwm txheej ntawm 90% txwv ceev.
Qhov kawg ceev ntawm roj lubricated bearings yog qis dua cov roj lubricated bearings. Nws yuav tsum tau muab sau tseg tias rau roj lubricated bearings, lawv txwv ceev yog feem ntau tsuas yog 80% ntawm cov kabmob qhov txwv ceev thaum siv lub zoo zoo rov qab voj voog roj system, tab sis rau cov roj pos huab lubrication systems, lawv txwv ceev yog feem ntau 50% siab dua. tib yam yooj yim lubrication system. Kev tsim thiab qauv ntawm lub tawb kuj cuam tshuam rau qhov kawg ceev ntawm cov kabmob.
6. Cov kabmob ua luam dej thiab axial hloov chaw
Feem ntau, ib tug ncej yog txhawb los ntawm ob bearings spaced ib tug tej yam kev ncua deb. Txhawm rau hloov mus rau qhov sib txawv ntawm qhov sib txawv ntawm thermal expansion ntawm lub ncej thiab lub plhaub, ib qho kev coj tus kheej yuav tsum tau kho nyob rau hauv qhov kev taw qhia axial thaum txhim kho, thiab lwm yam kabmob yuav tsum muaj peev xwm ua luam dej ntawm tus ncej (uas yog, ua luam dej. kev txhawb nqa), txhawm rau tiv thaiv qhov tshwm sim ntawm jamming tshwm sim los ntawm elongation lossis contraction ntawm lub ncej.
7. Yooj yim rau nruab thiab disassemble bearings
Thaum xaiv hom bearing, nws tseem yuav tsum tau txiav txim siab seb nws puas yooj yim rau nruab thiab disassemble, tshwj xeeb tshaj yog kev teeb tsa thiab disassembly ntawm cov kabmob loj thiab loj ntxiv.
Cov kabmob yog ib feem tseem ceeb ntawm cov cuab yeej siv tshuab.
Kev xaiv tsim nyog, kev ua haujlwm raug, thiab kev saib xyuas tuaj yeem txhim kho kev ua haujlwm thiab kev pabcuam lub neej ntawm bearings thiab khoom siv.
