The vibration of the bearing to your motor bearing noise, 2)

Motor bearing noise caused by the reason caused by total rolling element change of vibration: when a load on a bearing axial load, the total number of rolling element bearing load in operation will slightly change, caused the deviation of load bearing. Causing the vibration is inevitable, but can ease, according to the radial preload all load on rolling body ( Discomfort to cylindrical roller bearing) 。 Partly destroyed: because the actual operation or incorrect installation, small part of the bearing cage and rolling body is likely to damage. In operation, will cause the damage of bearing components special vibration frequency; Vibration frequency analysis can identify the damage of bearing components. This basic principle has been used in condition monitoring equipment, used to detect bearing damage. The precision of the related components: in the middle of the bearing and bearing seat or axis of rotation on inner and outer conditions closely, bearing inner and outer ring with poor appearance design to cooperate with each other and the deformation of adjacent components. If appear deformation, it is likely to cause vibration in the operation. Air pollutants: if machinery and equipment in environmental pollution, waste is likely to be into the bearing and roller rolling. Caused by the vibration level is by rolling the residue of the total number of particles, the size and composition. This kind of situation though it is not easy to cause the frequency of the typical way, but can hear an annoying noise. Motor bearing noise caused by the reason is very complex, one is the co-ordination bearing inner and outer surface damage. Because this kind of damage, destroy the bearings and housings, the interaction relationship between bearing and shaft, the centerline offset the appropriate parts. Sound was caused when the shaft move at high speed. When the bearing fatigue, its surface metal material loss, also can make the bearing axial gap expanded sound. In addition, bearing RunHua enough, dry friction, as well as its bearing grinding is the cause of abnormal sound. Bearing damage, loose cage damaged, can also cause motor bearing ring.
