[0002] Throughout the long history of mechanical transmission systems, shaft components have always played a core role, undertaking the crucial task of transmitting power and motion. Early traditional shaft designs were relatively simple, only capable of basic torque transmission, with significant functional limitations. As the industrial sector continues to advance towards higher precision, higher integration, and higher reliability, mechanical systems are becoming increasingly complex, posing stringent challenges to the performance of shaft components. Consequently, the application of multi-functional composite shafts is becoming increasingly widespread, integrating multiple functions and greatly improving the performance and integration of mechanical equipment. However, most current mainstream multi-functional composite shafts are of integral design.

[0003] Existing integrated multi-functional composite shafts often require replacement of the entire shaft if any part malfunctions, resulting in high repair costs and significant time consumption. For example, in industrial production lines, wear in one area of ​​the shaft can render the entire shaft unusable, causing prolonged downtime and substantial economic losses for the company. With continuous technological advancements, the integrated design also significantly increases the difficulty of upgrading the shaft's functionality. For instance, in automated equipment in smart factories, adding sensors to the shaft for real-time monitoring is difficult to achieve without replacing the entire component. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in the existing technology, once a certain part of the integral multifunctional composite structure shaft fails, the entire shaft often needs to be replaced, resulting in high maintenance costs and long time consumption.
