Research on mechanism of enhancing lubrication flow field regulation of high-speed bearing functional cage

Review of Wind Power Bearing Wear Analysis and Intelligent Lubrication Method Research

“…This exper mental study can provide a vital research basis for the study of the dynamic performanc of the bearing parameters, as well as bearings using gas lubrication to provide a new wa of thinking. Wei et al [197] designed a cage model with the wing structure (Figure 16 utilizing computational fluid dynamics software to simulate and analyze the angle, pos tion, and length of the wing and fluid flow field in the bearing cavity at different velocitie Through the simulation, the closer the cage wing is to the lubricant inlet and the appro priate change of the wing angle, the more obvious the regulation of the flow field in th Jin et al [196] designed a three-dimensional porous tilting tile bearing hybrid lubrication model, combined with the grid iterative algorithm, to analyze the viscoelastic and dynamic characteristics of tilting tile bearings with respect to the parameters of bearing rotor speed, tilting stiffness, and nominal clearance. Through the simulation experiments, it is concluded that the temperature rise inside the bearing of tilting tile bearing is lower than 3 K under air lubrication, and the adaptive pad motion of tilting tile bearing has better viscoelastic and dynamic characteristics under mixed lubrication.…”
