automated diagnosis of rolling element bearing

  • A Feature Extraction Method Based on Information

    Each bearing element has a characteristic rotational frequency With a defect on a particular bearing element an increase in vibrational energy at this element's rotational frequency may occur As mentioned previously the components that often fail in a rolling element bearing are the outer race the inner race the rollers and the cage
