🔍 Key Concepts

• Geared steam turbine main reduction gears and how load is transmitted on the tooth flanks • Why technicians use indicating dye/Prussian blue on specific teeth to check contact and wear patterns over time • Difference between pressure side (working flank) and back side of a gear tooth in ahead operation

💭 Think About

• Ask yourself: for long‑term comparison of wear, is it better to always use the same identified teeth or just any convenient pair each time? • Which side of the tooth actually carries the heavy, continuous load in ahead operation on a turbine reduction gear—and would that be the most important side to monitor? • Should a comparative pattern check be done on only the driving gears, or on all mating tooth surfaces that share the load?

✅ Before You Answer

• Verify which tooth flank is the ahead pressure side (working face) on a turbine reduction gear and why this specific side matters. • Check whether consistent numbering/identification of teeth (like No. 1 and 2 teeth) is important for getting repeatable, comparative readings over months/years. • Confirm if a proper survey of tooth contact should include all meshing gears in the train or just the driving pinions.
