Parameters ntawm kev xaiv bearing

Tso cai Bearing installation Chaw
Txhawm rau txhim kho cov kabmob hauv lub hom phiaj cov cuab yeej, qhov chaw tso cai rau cov kabmob dov thiab nws qhov chaw nyob ib sab feem ntau txwv yog li hom thiab qhov loj ntawm cov kabmob yuav tsum raug xaiv nyob rau hauv cov kev txwv.Feem ntau, txoj kab uas hla ntawm ncej yog tsau ua ntej ntawm nws cov rigidity thiab lub zog los ntawm tus tsim tshuab;Yog li ntawd, cov kabmob feem ntau xaiv raws li nws qhov loj me.Muaj ntau tus qauv tsim qauv thiab hom muaj rau dov bearings thiab xaiv qhov zoo tshaj plaws bearing los ntawm lawv yog ib txoj hauj lwm tseem ceeb.

Load thiab Bearing Hom
Load magnitude, hom thiab kev taw qhia ntawm kev siv load yuav tsum tau txiav txim siab nyob rau hauv kev xaiv hom bearing.Lub axial load nqa peev xwm ntawm ib tug bearing yog ze ze rau lub radial load peev xwm raws li nyob rau hauv lub bearing tsim.

Permissible Speed ​​thiab Bearing Types
Bearings yuav tsum tau xaiv nrog cov lus teb rau kev sib hloov ceev ntawm cov cuab yeej uas yuav tsum tau muab cov kabmob;Qhov siab tshaj plaws ceev ntawm dov bearings nws txawv nyob ntawm seb, tsis yog tsuas yog hom bearings, tab sis kuj nws qhov loj, hom tawb, loads ntawm lub cev, lubrication txoj kev, tshav kub dissipation, thiab lwm yam. Piv txwv li cov roj da dej lubrication txoj kev, hom bearing yog roughly qeb duas los ntawm kev ceev mus rau qis dua.

Misalignment ntawm Inner / Outer Rings thiab Bearing Hom
Sab hauv thiab sab nrauv yog me ntsis misaligned vim yog deflection ntawm ib tug ncej los ntawm kev siv loads, seem yuam kev ntawm lub ncej thiab vaj tse, thiab mounting yuam kev.Qhov tso cai tus nqi ntawm misalignment txawv nyob ntawm seb hom kabmob thiab kev ua haujlwm, tab sis feem ntau nws yog lub kaum sab xis me me dua 0.0012 radian.Thaum xav tau ib qho misalignment loj, bearings uas muaj peev xwm kho tus kheej, xws li tus kheej-aligning pob bearings, spherical roller bearings thiab bearings yuav tsum tau xaiv.

Rigidity thiab Bearing hom
Thaum cov loads raug yuam rau ntawm cov kabmob dov, qee qhov elastic deformation tshwm sim hauv qhov chaw sib cuag ntawm cov khoom dov thiab cov raceways.Lub rigidity ntawm cov kabmob yog txiav txim los ntawm qhov sib piv ntawm cov kabmob load rau tus nqi ntawm elastic deformation ntawm lub puab thiab sab rings thiab dov ntsiab.Qhov siab dua qhov rigidity uas bearing muaj, zoo dua lawv tswj elastic deformation.Rau lub ntsiab spindles ntawm cov cuab yeej siv tshuab, nws yog ib qho tsim nyog yuav tsum muaj siab rigidity ntawm cov bearings ua ke nrog rau qhov seem ntawm spindle.Yog li ntawd, txij li cov menyuam bearings yog deformed tsawg dua los ntawm kev thauj khoom, lawv tau xaiv ntau dua li cov pob bearings.Thaum yuav tsum tau muaj siab rigidity, bearings tsis pom zoo clearance.Angular contact pob bearings thiab tapered roller bearings feem ntau preloaded.
