Which of the following factors determines the type of construction used for gear hubs in shipboard reduction gear units?

🔍 Key Concepts

• Relationship between turbine design and the reduction gear that connects it to the shafting • How torque, speed, and loading characteristics affect gear hub construction • Difference between ship characteristics vs. prime mover (steam turbine) characteristics

💭 Think About

• Ask yourself: Which factor most directly affects how the gear transmits power from the turbine to the shaft? • Consider: Is the hub construction more sensitive to the physical size of the gear, the type of ship, or the mechanical characteristics of the driving machine? • Think: Which choice would a gear designer need to know first before specifying hub design details like fit, keys, and materials?

✅ Before You Answer

• Identify which option is tied to the prime mover’s mechanical behavior (speed, torque, thermal effects). • Separate factors that are mainly operational/ship use from those that govern mechanical design of the gear train itself. • Verify which factor would still matter even if the same gear were installed on different ships.
