Although this study has made significant progress in the thermal analysis and surface texture characteristics of high-speed lubricated bearings, there are still some limitations. Firstly, the research on the coupling of temperature and dynamics is still limited. Secondly, the formation mechanism and multi-objective collaborative optimization of convex texture friction pair performance have not been fully studied. Lastly, the influence of different coating materials and lubricating oil additives on the surface performance of friction pairs of high-speed lubricating bearings needs to be explored further.
In future research, it is necessary to establish a bearing stress field coupling model under the complex working conditions of actual aero-engine high-speed lubricated bearings to obtain more accurate bearing dynamic performance and temperature distribution. Additionally, exploring the influence of surface texture on rolling bearings’ bearing capacity and friction performance can lead to new insights into optimizing convex texture friction pair performance with intelligent algorithms. Finally, studying different coating materials and lubricating oil additives’ impact on friction pair surface performance can help improve high-speed lubricating bearings for aero-engines in various environments.
