Lub rigidity ntawm cov kabmob yog lub zog yuav tsum tau ua kom cov kabmob deformation.Lub elastic deformation ntawm dov bearings yog me me heev thiab tuaj yeem tsis quav ntsej hauv ntau lub tshuab.Txawm li cas los xij, hauv qee lub tshuab, xws li tshuab cuab yeej spindles, bearing rigidity yog ib qho tseem ceeb.Cylindrical thiab tapered cov menyuam bearings feem ntau yog siv.Vim hais tias ob hom bearings raug load, lub ntsiab dov thiab cov raceways nyob rau hauv txoj kab kev sib cuag, thiab elastic deformation yog me me thiab rigidity yog zoo.Txhua yam ntawm cov bearings kuj tuaj yeem ua ntej nruj kom ua kom lub zog ntawm kev txhawb nqa.Piv txwv li, angular contact ball bearings thiab tapered roller bearings, txhawm rau tiv thaiv kev vibration ntawm lub ncej thiab ua kom lub zog ntawm kev txhawb nqa, qee qhov axial quab yuam feem ntau siv rau lub sijhawm ntawm kev teeb tsa los nias lawv tawm tsam ib leeg.Ntawm chav kawm, tus nqi pre-tightening yuav tsum tsis txhob loj heev.Yog tias nws loj dhau, qhov kev sib txhuam ntawm cov kabmob yuav nce thiab qhov kub thiab txias yuav nce ntxiv, uas yuav cuam tshuam rau lub neej kev pabcuam ntawm cov kabmob.
