Question 1 of 31048

In a typical gas turbine propulsion plant, the main thrust bearing directly positions which part(s) of the main reduction gear?

🔍 Key Concepts

• Function and location of the main thrust bearing in a propulsion shaft line • How axial thrust from the propeller is transmitted through the main reduction gear • Relative positions of high-speed and low-speed gears and pinions in a typical marine gas turbine reduction gear layout

💭 Think About

• Which component of the reduction gear is directly in line with the propeller shaft and would logically be controlled in its fore-and-aft position by the main thrust bearing? • Does the main thrust bearing usually act on a gear, a pinion, or a shaft—and which of the listed options is most physically connected to the propeller thrust? • Think about which part turns the slowest and is closest to the propeller in a gas turbine reduction gear system.

✅ Before You Answer

• Identify which element (gear or pinion) is on the output shaft that connects toward the propeller • Confirm which component actually needs its axial position controlled to transmit thrust safely to the hull structure • Eliminate any option that is more closely associated with the turbine input side rather than the propeller output side
