Our girth gear specialist team conducts gear inspections and risk assessments based on the inspection recommendations outlined in the annex of AGMA 6014. Part of this inspection is a visual and photographic inspection of the teeth, recording damage in accordance with the terminology outlined in AGMA 1010-F14. With the introduction of ASTM E2905 an improved cleaning and tooth inspection method is available that quickly detects and accurately maps surface breaking indications and cracks on gear teeth. Inspections per ASTM E2905 are powerful standalone inspections, but when combined with classic inspections per the inspection recommendations in AGMA 6014 the result is a complete snapshot of the girth gear system’s condition.
Combining E2905 into our inspections has enabled Global’s team to refine our girth gear risk assessments and add clarity to our girth gear asset management recommendations helping our customers make informed condition based decisions. This practice standardizes the inspection method for large ring gears and pinions, delivering consistency, efficiency and standardization ‐ a service valued worldwide. With the correct preparation, the gear set will take approximately five to six hours to inspect.
American Gear Manufacturers Association (AGMA) recognizes ASTM E2905 as an accepted method of gear teeth inspection in AGMA 919‐1‐A14, Condition Monitoring and Diagnostics of Gear Units and Open Gears and is in AGMA 6014 – Annex G – Operations & Maintenance.
