Abstract：Aiming at the limitations of current monitoring methods in the accuracy of early fault diagnosis for rolling mill bearings,a structural design method for intelligent rolling mill bearings based on embedded multi-source microsensors was proposed.A multi-source microsensor module integrating temperature and acceleration signals was developed,and an optimized layout structure of axial sensing leads in the bearing housing was designed,breaking through the bottleneck of sensor integration under the space constraints of traditional bearings.A mechanical performance evaluation system for the slotted structure was established,and the reliability of the intelligent structure was verified through strength check and service life calculation.The results showed that when the slotted area was 10 mm×5 mm,the maximum equivalent stress was 99.71 MPa,which had sufficient safety margin compared with the material yield limit;the maximum overall deformation of the structure was only 0.24 mm,and the local deformation was less than 0.02 mm,with the theoretical service life consistent with that of conventional bearings.The optimized intelligent bearing ensured monitoring functionality while meeting industrial application requirements in terms of structural strength and service life.The research results not only provide a high-precision monitoring method for early fault diagnosis of rolling mill bearings under extreme working conditions but also achieve an integrated"monitoring-structure"process through embedded design.Its strength check standards and service life evaluation methods can directly guide the transformation and upgrading of intelligent bearings in industrial sites,holding significant engineering value for improving the operation and maintenance efficiency of rolling production lines.
