Gearbox Field Inspections: Load Distribution, Lubrication, and Condition Monitoring

January 1, 1970

Gears can fail due to various damage patterns. In this study, the combined influence of shaft misalignments and gear lead crown on load distribution and tooth bending stresses is applied to real world circumstances.

After attending Part I, students will be able to:

  • Identify damage patterns that occur as a result of various stresses during operations.
  • Provide an analysis and corrective plans to avoid toothing distress.
  • Have a deeper understanding of the unique attributes of load distribution effects.
  • Interpret the connection between gear design and inspections and maintenance.
  • Identify key design attributes which lend to maintenance friendly requirements for gears.
  • Apply and relate theoretical frameworks in gear load distribution.

Both the operator and designer must consider gear tribology. In this second part of our series, the focus will be placed on lubrication.

After attending Part II, students will be able to:

  • Identify factors to avoid gear failures
  • Have a deeper understanding of Elastohydrodynamic (EP) Lubrication
  • Identify the differences between primary and secondary modes of failure
  • Describe how the choice of lubricant affects the life of the gear unit
  • Explain the effects of EP additives

Gearbox diagnostics and service are critical to the field inspection process. In this third part of our series, instructors will explore these concepts in depth.

After attending Part III, students will be able to:

  • Perform gearbox diagnostics, understand and interpret the results
  • Have the ability to apply techniques in the implementation of an appropriate preventative gear maintenance program. 
  • Use service concepts as it relates to preventive gear maintenance

Speakers: John B. Amendola, John B. Amendola III, and Dereck Yatzook
