Kev nkag siab qhov kev siv txoj haujlwm ntawm tus kheej kheej cov menyuam kabmob hauv cov cuab yeej siv tshuab, cov kev siv thiab ib puag ncig ib puag ncig yog qhov yuav tsum tau ua ua ntej rau kev xaiv tus kheej kheej kheej kheej rau cov menyuam kabmob. Rau lub hom phiaj no, cov ntaub ntawv thiab cov ntaub ntawv hauv qab no yuav tsum tau:
(1) Kev ua haujlwm thiab cov qauv ntawm cov cuab yeej siv tshuab
(2) Siv cov khoom ntawm cov menyuam kheej kheej bearings
(3) Spherical roller bearing load (loj, kev taw qhia)
(4) Kev sib hloov ceev
(5) Kev vibration thiab poob siab
(6) Spherical roller bearing kub (ambient kub, kub nce)
(7) Ambient cua (corrosive, huv si, lubricating)
Rigidity ntawm spherical roller bearings
Lub rigidity ntawm ib tug kheej kheej kheej bearing yog txiav txim los ntawm tus nqi ntawm elastic deformation uas tshwm sim thaum nws nyob rau hauv load. Feem ntau, qhov deformation no me me thiab tuaj yeem tsis quav ntsej, tab sis nyob rau hauv qee lub tshuab, xws li tshuab cuab yeej spindle systems, spherical roller Lub zog zoo li qub thiab dynamic rigidity ntawm sub-bearings muaj kev cuam tshuam zoo rau cov yam ntxwv ntawm lub cev. . Spherical roller bearings muaj qhov nruj dua li pob bearings. Ntau hom bearings kuj tuaj yeem txhim kho qhov nruj kom sib txawv los ntawm kev "preloading".
Spherical roller bearings haum rau cov khoom hnyav
Qhov loj ntawm qhov load Qhov loj ntawm qhov load feem ntau yog qhov kev txiav txim siab hauv kev xaiv ntawm cov kabmob loj. Cov menyuam bearings muaj peev xwm nqa tau ntau dua li cov pob bearings nrog tib qhov ntev ntawm sab nraud. Feem ntau, pob bearings yog haum rau lub teeb los yog nruab nrab loads, thiab cov menyuam bearings yog haum rau hnyav loads.
Load hom Ntshiab radial load tuaj yeem xaiv qhov sib sib zog nqus groove pob bearing thiab cylindrical roller bearing. Rau cov ntshiab axial load, thrust pob bearing thiab thrust cylindrical roller bearing tuaj yeem xaiv. Thaum muaj radial load thiab axial load (combined load), angular contact pob bearings lossis tapered roller bearings feem ntau yog siv. Yog hais tias lub radial load loj thiab axial load yog me me, sib sib zog nqus groove pob bearings thiab cylindrical roller bearings nrog tav ntawm lub puab thiab sab nraud rings tuaj yeem xaiv. Yog hais tias tseem muaj qhov loj deformation ntawm lub ncej los yog vaj tse thiab kev txhim kho tsis zoo, kev sib koom ua ke ntawm tus kheej pob bearings thiab tus kheej-aligning roller bearings tuaj yeem xaiv. Yog hais tias lub axial load loj thiab lub radial load me me, lub thrust angular contact pob bearing tuaj yeem xaiv. Yog hais tias plaub-point contact pob bearing kuj xav tau kev ua haujlwm ntawm tus kheej, qhov thrust spherical roller bearing tuaj yeem xaiv.
