Question 375Steam Plants - 1st Asst/Chief70% to pass
Regarding main reduction gears, when high speed first reduction pinions and gears are connected to low speed pinions and gears, each contained in a sequential portion of the gear housing, the reduction gear unit is known as _______________.
AI Explanation
The correct answer is A) articulated.
When high-speed first reduction pinions and gears are connected to low-speed pinions and gears, each contained in a sequential portion of the gear housing, the reduction gear unit is known as an articulated reduction gear. This configuration allows for the different gear components to be arranged in a modular, sequential manner within the gear housing, providing flexibility in the overall gear system design.
The other options are incorrect because:
B) Locked train refers to a fixed, non-modular arrangement of the gears.
C) Nested refers to a concentric arrangement of the gears, not a sequential one.
D) There is a specific term that applies to this type of gear configuration, so "none of the above" is not the correct answer.
