Question 538Steam Plants - Assistant Engineer

The correct answer is C) transmit the force produced by the propeller to the structure of the ship. Thrust bearings in a reduction gear drive system are responsible for transmitting the thrust force generated by the propeller to the ship's structure. This ensures that the propeller's thrust is effectively transferred to the vessel, rather than being absorbed by the engine or other components. The thrust bearings act as an interface between the rotating propeller shaft and the stationary ship's structure, allowing the thrust to be safely and efficiently transmitted. The other options are incorrect because they do not accurately describe the primary function of thrust bearings in a reduction gear drive system. Thrust bearings do not increase shaft speed (A), limit radial movement of the shaft (B), or hold the main engine in place (D).
