Machine Bearings Testing TRIZ Cases
- Magnetic Bearing Shaft Bend Detection Using Displacement Sensors
A processor calculates rotating shaft center positions using displacement sensors to determine bend status.
- Bearing Revolution Estimation via Dynamic Sensor Wake-Up Intervals
Estimates bearing revolutions using dynamic sensor wake-up intervals and traveled distance offsets to conserve energy.
- Bearing Spall Propagation Model Calibration via Vibration Spectral Analysis
A bearing calibration device determines spall propagation stages using vibration spectral analysis to predict defect size accurately.
- In-situ Grease Condition Monitoring via Multi-Frequency Impedance
Multi-frequency alternating voltage measures complex grease impedance to determine composition.
- Bearing Groove Profile Measurement via Rotational Probe
Rotating the probe around the groove center eliminates two-axis movement, reducing mechanical load on the sensor while maintaining high measurement precision.
