Under the non-rotating condition of the bearing at rest, or at a certain speed, the dynamic characteristics of the NSK
bearing are analyzed by external excitation, which represents the ability of the NSK bearing to resist external interference under the special conditions. The characteristics required for the dynamic analysis of the rotor refer to the amount of eddy (the corresponding radial displacement) generated by the
bearing under the action of the unbalanced force of the rotor or other periodic forces, namely the so-called equivalent stiffness and corresponding Effective damping.
The dynamic characteristics of NSK
bearings are affected by many factors such as structural parameters, operating conditions, load conditions and lubrication environment of the bearing, which are reflected in the elastic contact between the rolling elements and the inner and outer rings, and the formation between the rolling elements and the inner and outer rings. The thickness of the lubricating film changes, the presence and variation of the bearing clearance. Therefore, the analysis of the dynamic characteristics of NSK bearings involves the elastic deformation and elastic hydrodynamic lubrication analysis of solid contact and their mutual influence correction.
