AI Technical Summary
Existing technologies require multiple holes to be drilled in the bearing surface when monitoring various operating parameters of sliding bearings. This reduces the bearing area and increases the operational risk. Furthermore, the monitoring results of each parameter fail to establish a corresponding relationship, affecting the comprehensiveness of the bearing's operating status analysis.
Design an integrated sensor for life and condition identification of sliding bearings. The sensor uses a first conductive core and a second conductive core as life prediction conductive cores, and a third conductive core as condition identification conductive core. By embedding and equipping resistive layers of different thicknesses in the insulator, the sensor achieves integrated monitoring of life and condition. The conductive cores are designed to be redundant for data verification.
The number of bearing openings has been reduced, improving the reliability and accuracy of life prediction. It can accurately determine the wear of bearings throughout their entire life cycle, thus improving the comprehensiveness and precision of monitoring.
