This paper presents a useful tool, which combines the fundamental circuit and a block diagram, to analyze the angular velocity of an epicyclic gear train. It is a visualized and straightforward method without manipulating tedious kinematic equations, which makes the angular velocity analysis of epicyclic gear trains more simplified. A compound epicyclic gear train used in a synchronous differential device is taken as an example to demonstrate the analysis process of the proposed approach. The velocity ratio of the epicyclic gear train is also derived.}, journal={Proceedings of Engineering and Technology Innovation}, author={Wu, Yi-Chang and Tsai, Mi-Ching}, year={2017}, month={Sep.}, pages={28-31} }
