🔍 Key Concepts

• Identify that the illustration shows a lubricated, gear-type flexible coupling with a floating member between two flanges. • Recall where pinion shafts and turbine rotors are located in a geared turbine propulsion train (from turbine to reduction gears to bull gear to line shaft). • Distinguish between high‑speed components (turbines and pinions) and low‑speed components (bull gear and line shaft) in terms of shaft size and coupling design.

💭 Think About

• Look at the labels: "pinion flange," "turbine flange," and a floating member. Which two elements of the power train would logically be joined by a coupling with those names? • In a modern geared turbine unit, which side of the gear train needs a flexible, lubricated coupling to accommodate misalignment and thermal expansion: the high‑speed turbine/pinion side, or the low‑speed bull gear/line shaft side? • Compare the apparent shaft diameters and the need for lubrication shown in the figure with what you would expect between a bull gear and line shaft versus between a turbine rotor and a pinion.

✅ Before You Answer

• Confirm which components actually mesh by gears (these will not be connected by a coupling like the one shown). • Verify that a part labeled "pinion flange" would logically be attached to a pinion shaft, not to a bull gear or line shaft. • Make sure the coupling’s design (high‑speed, small‑diameter shafts, oil‑lubricated gear teeth) matches the part of the train that operates at turbine speed rather than at propeller speed.
