249. Which of the following statements is true concerning the coupling shown in the illustration
The illustrated floating gear-type flexible coupling is designed to connect a main turbine to a high-speed pinion in a geared turbine installation. This type of coupling is used for high-speed, high-power turbine drives and requires accurate shaft alignment, unlike options suggesting unlimited misalignment. It is suitable for main propulsion duties, not limited to small auxiliary turbines, and is not typically used between reduction gears.
