WhenTapered roller bearings operation if there rhythmic percussion or crash

When bearing operation if there rhythmic percussion or crash , probably due to the cylindrical roller bearing raceway spalling, indentation , or other parts caused by improper installation ;  2)  bearings have found "Goo busy , goo busy "sound, may be due to the bearing Mifengbuyan , oil is not clean , bearing clearance caused by too much ;  3) found bearing the" enjoin squeak , squeak enjoin " screaming sound , may be due to dry lubricant or lack of lubricant caused ;  4) If it is found tapered roller bearings  the " Falling " sound , may be cylindrical roller bearings are not clean, interior mixed with debris , sand , dust and other debris caused by ;  5) excessive heat expansion of the bearing inner ring , bearings and seals and related parts friction ;  6) when installing bearings, thrust ball bearing  or other parts due to beating , causing bearing deformation ;  7) bearings the adapter sleeve too tight or loose ;  8) of the bearing housing oversize ( including the use of larger ) , causing  bearing outer ring rotates in the bearing seat  and so on, are likely to make bearings noise and unusual sound. Cylindrical roller bearings causes vibration , basically causes abnormal bearing noise and sound the same , there is a strong correlation between the two.
