1. The amount of rolling load that occurs in arousing; the radial load of a load bearing; the amount of rolling carried by it will change slightly during operation; during this period: 2 -3-2-3. . . . This causes a shift in the direction of the load. The resulting oscillations are unavoidable; but can be preloaded; to reduce the axial loading of all the tumblers.
2. Some damage is in operation; specific oscillating frequencies occur across the tumbling of damaged bearing components. Frequency profiling can identify damaged bearing components. This criterion has been used for condition monitoring equipment to detect bearing damage. The temperature will rise sharply; abnormal high temperature will occur. The reasons are such as excessive smoothing agent, too small bearing clearance, poor equipment, excessive conflict of sealing equipment, etc. High-speed rotation; FAG imported bearing layout, smooth selection of fault method, etc. Its reason.
3, associated with some of the accuracy of the shaft and FAG bearing; close to the bearing ring touch conditions; can be compatible with the shape deformation of the nearby parts. If there is distortion in the operation can cause a sensation. Therefore; bearing and The public service of the shaft processing needs is very important.
4. Contaminants if you are operating in a polluted environment; impurities can enter the tumbling of German FAG bearings. The oscillation depends on the amount of tumbling impurities; planning and composition; although the frequency does not occur in a typical way; Poor precision of the shaft or housing, bearing damage, foreign matter intrusion, etc.; but you can hear an annoying noise
