Question 666Steam Plants - Assistant Engineer70% to pass
The jacking/turning gear mechanism of a main propulsion geared turbine installation is normally connected through mechanical linkage to the _______________.
AI Explanation
The correct answer is A) high-speed pinion rotor.
The jacking/turning gear mechanism is typically connected to the high-speed pinion rotor of a main propulsion geared turbine installation. This allows the rotor to be turned slowly during maintenance or startup procedures, without engaging the full power of the turbine.
The other options are incorrect because:
B) The low-speed pinion rotor is not directly connected to the jacking/turning gear.
C) The low-speed gear rotor is also not the component connected to the jacking/turning gear.
D) The bull gear is a large, slow-turning gear, and is not the component connected to the jacking/turning gear.
