TIMKEN bearings part of the wave. Bearing rings and bearings or shafts of the close fit between cases, TIMKEN bearing ring might dovetail shape and deformation of the adjacent parts. If the deformation occurs, there may be in the running vibration. Thus, the TIMKEN bearing and shaft to be machined to tolerances that you want is important.
Bearing vibration due to load rolling quantity change. When a radial load is loaded on when a TIMKEN bearing, its bearing load of scroll amount may vary slightly in the running, that is causing a load offset in that direction. The vibration was inevitable at this point, but provide an axial preload to reduce load all the rolling (not applicable for cylindrical roller bearings TIMKEN).
Bearing local damage. Because the operation or installation errors, a small number of TIMKEN bearing raceways and rolling elements may be damaged. Running, scroll TIMKEN bearings damaged parts will have a specific vibration frequency. TIMKEN bearings vibration frequency analysis can identify damaged parts.
End of the TIMKEN bearing vibration reduction methods are: removal of critical excitation vibration from the application; inhibition resistance inspired critical excitation vibration between parts and resonant part; changing the stiffness of structure, thereby altering the critical frequency of three.
