🔍 Key Concepts

• Main reduction gear arrangements used on large marine propulsion systems • Difference between single reduction, double reduction, and compound gearing • How gear sets are arranged when high-speed and low-speed sections are in separate, sequential housings

💭 Think About

• Ask yourself: when two stages of reduction (high-speed then low-speed) are placed in separate but successive sections of the same housing, what general type of gearing arrangement is that called? • Think about which term describes the layout of multiple gear trains in series, rather than how the teeth mesh or whether gears are locked together. • Consider what each option typically refers to in machinery: does it describe gear train layout, gear tooth loading, or something else?

✅ Before You Answer

• Verify which term is commonly used in marine engineering texts to describe high-speed and low-speed pinions/gears placed one after the other in the same housing. • Check that the option you choose refers specifically to a type of reduction gear arrangement, not just a general mechanical concept. • Make sure the term you select is associated with multiple reduction stages in sequence rather than gears sharing the same wheel or being arranged side‑by‑side.
