Which of the following statements is true concerning the coupling shown in the illustration? Illustration SE-0001

Correct Answer: Option A — It can be used to connect the main turbine to the high-speed pinion.

Gear-type flexible couplings are universally applied to connect high-speed marine steam turbine rotors directly to the high-speed reduction gear pinions, efficiently compensating for axial thermal growth differentials while transmitting high torque under continuous rotation.
