A Study on Kinematic Characteristics of Planetary Gear Train

Gear trains are used in many machinery for variable speed ratios. Typical shapes of gear trains are tivo categories : simple gear trains and planetary gear trains. This paper presents the kinematic ctraracteristics for planetary gear trains. The characteristics are the constraints of geometric relationships, number of gears, speed of each gear. and speed ratio of the train. The objective goal of this paper provides the CAI) software, which is the academic tool for understanding the kinematics of the planetary gear trains.
