What is another word for sun gear?
Pronunciation: [sˈʌn ɡˈi͡ə] (IPA) 
The term "sun gear" refers to a gear component in a planetary gearing system that is located at the center of the system. This gear is surrounded by two or more planet gears and an outer ring gear, and it is responsible for transferring torque from the input shaft to the planetary gears. While "sun gear" is the commonly used term, there are several synonyms that may be used to describe this component, including "central gear," "output gear," and "epicyclic gear." Each of these terms offers a slightly different perspective on the function and location of the sun gear within the larger planetary system, providing engineers and mechanics with a range of options when discussing and designing these complex systems.
