|5. Passing vibration frequency|
|As the rolling elements pass the loading position, even
under normal operation, a small vibration can occur due to elastic deformation
of components (inner ring/outer ring/ball).
This is called passing vibration of rolling elements. A failure on the contact surface of the components may generate vibration as rolling elements pass the failure position. The frequency of such vibration differs depending on where the failure lies; therefore, it is possible to learn whether the bearing has a failure, and if so, where, simply by measuring the vibration frequency of the system and comparing it with calculated values.
For calculation of such vibration frequency, use the Menu entitled Passing Vibration Frequency.
