The reduction gear shown in the illustration is a/an _______________. Illustration SE-0013
AI Explanation
The correct answer is B) articulated double reduction gear.
The illustration SE-0013 depicts an articulated double reduction gear, which is a type of reduction gear commonly used in marine propulsion systems. This gear consists of two reduction stages, where the input power is reduced in two steps to match the optimal rotational speed of the propeller.
The other options are incorrect because:
A) A locked-train double reduction gear refers to a different type of reduction gear that does not have the articulated design shown in the illustration.
C) A nested double reduction gear has a different internal arrangement compared to the articulated design.
D) A nested four-step reduction gear has an additional reduction stage, which is not the case in the provided illustration.
