🔍 Key Concepts

• Reduction gears and how they change speed vs. direction of rotation • How reversing propeller thrust is normally accomplished on large vessels • How reduction gears can connect one engine to many shafts or many engines to one shaft

💭 Think About

• Think about whether reduction gears themselves normally reverse the direction of propeller thrust, or if another component usually handles ahead/astern. • Consider if reduction gears are ever used to take power from more than one engine and combine it, or from one engine and split it to more than one shaft. • Ask yourself: do reduction gears usually provide shaft direction reversal, shaft thrust reversal, or just speed and torque changes plus power combining/splitting?

✅ Before You Answer

• Verify how ahead/astern propulsion is usually achieved: by the gear set itself, or by a controllable-pitch propeller (CPP) or reversing engine/gear feature. • Confirm that reduction gears can be arranged for twin-input/single-output or single-input/twin-output configurations in marine plants. • Check whether "propeller thrust reversal" is a realistic function of reduction gears alone, or if that wording is misleading.
