Shedding light on mechanisms
underlying issues with bearings

Development aims

To use AE measurements to shed light on the seizure mechanism and use these measurements in the material-design process
To use NV measurements to shed light on the vibration transmission mechanism and use these measurements in the process by which NV-reduced designs are produced

Confirming effectiveness

Seizures

Using AE measurements to understand in real time the process by which bearing materials become damaged

fig1. Changes in AE frequencies in the course of conducting seizure testing

Clarifying the mechanisms by which bearings undergo seizures

NV

Understanding vibration-affecting axial center behavior through axial center trajectory measurements

fig2. Gap sensor mounting positions
fig3. Results of measuring the trajectory of the axial center
fig4. Time transition of the acceleration of the axial center and vibration
fig5. Correlation between the acceleration of the axial center and vibration

Clarifying the mechanism by which vibration is transmitted
