Abstract:

High-performance rolling bearings, as essential components of major equipment, are increasingly in demand for intelligent capabilities in fields such as wind power, engineering machinery, and rail transportation. Firstly,the technical characteristics of smart bearings are analyzed, and the related research progress and development trends at home and abroad are summarized. Then, the system composition, working principle and key technologies of the smart bearing embedded perception microsystem are mainly discussed, including integrated functional-structural design, sensing mechanisms and digital sensing technology, precision manufacturing and assembly processes, as well as performance testing and experimental evaluation. Finally, the future development trends and application potential of smart bearing technology are expounded and predicted, providing theoretical and practical guidance for technological innovation and industrialization in related fields.

Key words: smart bearing, perception microsystem, integrated design of functions and structures, sensor in-situ fabrication, status monitoring, fault diagnosis
