Kev xaiv cov menyuam bearing hom
Jul 11, 2022| Thaum xaiv bearings, lub ntsiab kev txiav txim siab yog raws li nram no:
Load ntawm bearing
Qhov loj, kev taw qhia thiab qhov xwm txheej ntawm kev thauj khoom ntawm cov kabmob yog qhov tseem ceeb hauv kev xaiv cov kabmob.
Thaum xaiv cov bearings raws li qhov loj ntawm lub load, piv nrog cov ntsiab lus ntawm cov kabmob ntawm cov kabmob, cov khoom tseem ceeb ntawm cov menyuam bearings yog nyob rau hauv kab sib cuag, uas yooj yim rau dais lub load, thiab deformation tom qab bearing kuj yog me me.
Thaum xaiv bearings raws li cov kev taw qhia load, thrust bearings feem ntau xaiv rau cov ntshiab axial loads. Xaiv thrust roller bearing rau lub zog loj dua axial. Xaiv thrust pob bearing rau me me axial quab yuam. Rau cov ntshiab radial load, sib sib zog nqus groove pob bearings, cylindrical roller bearings lossis rab koob rau cov menyuam bearings feem ntau xaiv. Thaum bearing radial load thiab me me axial load, sib sib zog nqus groove pob bearing lossis tapered roller bearing tuaj yeem xaiv tau; Thaum lub axial load loj, angular hu rau pob bearings lossis tapered menyuam bearings nrog lub kaum sab xis loj tuaj yeem xaiv tau.
Ceev ntawm bearing
Feem ntau, qhov ceev yuav tsis muaj kev cuam tshuam rau kev xaiv ntawm cov kabmob, tab sis thaum qhov ceev yog loj, qhov ceev yuav tsum tau suav nrog hauv cov qauv ntawm kev xaiv cov kabmob.
(1) Piv nrog rau cov menyuam bearings, pob bearings muaj kev txwv ntau dua, yog li nyob rau hauv cov ntaub ntawv ntawm kev kub ceev, pob bearings yog nyiam.
(2) Nrog tib txoj kab uas hla sab hauv, qhov me me ntawm sab nraud yog, qhov me me ntawm qhov dov yog, yog li lub zog centrifugal ntxiv los ntawm cov khoom dov ntawm lub nplhaib sab nraud yog me dua, yog li nws tsim nyog ua haujlwm ntawm kev kub ceev. Raws li nws qhov xwm txheej, koob rau cov menyuam bearings yog qhov tsim nyog rau kev ua haujlwm ntawm kev kub ceev.
Self aligning kev ua tau zoo ntawm bearing
Thaum txoj kab nruab nrab ntawm lub ncej tsis sib haum nrog txoj kab nruab nrab ntawm lub rooj zaum bearing thiab muaj lub kaum sab xis yuam kev, lossis thaum lub ncej yog khoov lossis qaij vim yog lub zog, lub axis ntawm sab hauv thiab sab nraud ntawm cov kabmob yuav yog. deflected. Nyob rau lub sijhawm no, yuav tsum tau siv cov kabmob ntawm tus kheej nrog qee qhov kev ua haujlwm ntawm tus kheej lossis ib lub pob kheej kheej kheej kheej nrog lub rooj zaum.
Cov menyuam bearings yog qhov tseem ceeb tshaj plaws rau qhov deflection ntawm bearings, thiab cov kabmob muaj peev xwm ntawm cov kabmob no yuav qis dua li ntawm pob bearings hauv lub xeev ntawm deflection. Yog li ntawd, thaum lub taub hau nruj thiab qhov kev txhawb nqa nruj ntawm lub qhov rooj bearing yog qhov tsawg, lossis thaum muaj lub sijhawm loj deflection, hom kabmob no yuav tsum zam kom deb li deb tau.
Bearing installation thiab disassembly
Thaum lub rooj zaum bearing tsis muaj qhov sib cais thiab cov khoom yuav tsum tau nruab thiab disassembled raws li axial kev taw qhia, cov bearings nrog cais sab hauv thiab sab nraud (xws li N0000, na0000, 30000, thiab lwm yam. ) yuav tsum nyiam.
