🔍 Key Concepts

• Typical sealing methods used with high-speed rotating shafts in gas turbine gearboxes • Differences between contact seals (that touch the shaft) and non-contact seals (that use clearances and pressure differences) • Why gas turbine gearboxes must control oil leakage while handling high temperatures and speeds

💭 Think About

• First, think about which seal types are designed for very high shaft speeds with minimal wear over time. • Consider which options are more commonly found in internal combustion engine crankshafts versus turbine gearboxes. • Ask yourself which seal design best uses close clearances and pressure/oil flow management instead of direct rubbing contact to keep oil contained.

✅ Before You Answer

• Identify which of the choices is typically a non-contact seal suitable for high-speed operation. • Eliminate any seals that would quickly overheat or wear out if used on a high-speed turbine gearbox shaft. • Verify which seal type is commonly associated with gas turbine main bearings and gearboxes in standard marine engineering references.
