Standard Guide for Monitoring Failure Mode Progression in Plain Bearings

Importancia y uso:

5.1 This standard is intended as a guideline for the justification of oil test selection for monitoring plain bearing conditions. One should employ a continuous benchmarking against similar applications to ensure lessons learned are continuously being implemented.

5.2 Selection of oil tests for the purpose of detecting plain bearing failure modes requires good understanding of equipment design, operating requirements, and surrounding conditions. Specifically, detailed knowledge is required of bearing design configuration, dimensional tolerances, load directions, design limitations, lubrication mechanisms, lubricant characteristics, and metallurgy of lubricated surfaces. Equipment criticality and accessibility as well as application of other monitoring techniques (for example, vibration, ultrasound, or thermal images) are also critical information in this analysis process. In addition, detailed knowledge of the lubricating oil is paramount.

5.3 To properly apply the FMEA methodology, users must understand the changes encountered in the system during all operating modes, their impact on design functions, and available monitoring techniques capable of detecting these changes. To demonstrate this approach, Section 6 will provide extensive descriptions of the plain bearing failure modes, their causes, and effects.
