Kuoma kwebearing ndiko simba rinodiwa kuita kubereka deformation.Iyo elastic deformation ye rolling bearings idiki kwazvo uye inogona kufuratirwa mumashini mazhinji.Nekudaro, mune mimwe michina, senge muchina chishandiso spindle, kutakura kuomarara chinhu chakakosha.Cylindrical uye tapered roller bearings anowanzo shandiswa.Nekuda kwekuti iwo maviri marudzi emabearings ari pasi pekuremerwa, iyo inotenderedza zvinhu uye mijaho iri mumutsara wekubatana, uye elastic deformation idiki uye kuomarara kwakanaka.Ese marudzi emabearings anogona zvakare kuve akasimbiswa kare kuti awedzere kuoma kwerutsigiro.Semuenzaniso, angular contact ball bearings uye tapered roller bearings, kuitira kudzivirira kuzununguka kweshaft uye kuwedzera kusimba kwekutsigirwa, imwe axial simba rinowanzoshandiswa panguva yekuisa kuvatsikirira kune mumwe nemumwe.Zvechokwadi, iyo pre-tightening chiyero haifaniri kunge yakakura zvikuru.Kana yakakura kwazvo, kuputika kwekutakura kuchawedzera uye kuwedzera kwekushisa kuchawedzera, izvo zvichakanganisa hupenyu hwebasa rekutakura.
