Geometric design of a planetary gear train with non-circular gears

Mechanism and Machine Theory, 2006
Abstract The paper presents a concept of epicyclical gear train able to generate a variable gear ratio law. The basic mechanical configuration consists of three non-circular gears in a typical planetary arrangement. Such a mechanism couples the advantages of non-circular gears with the typical performances of epicyclical gear trains.

Modeling and Dynamics Analysis of Non-Circular Gears

Proceedings of the 2020 2nd International Conference on Big Data and Artificial Intelligence, 2020
Compared with circular gear, the tooth shape, pitch diameter, tooth profile equation and meshing characteristics of non-circular gear are constantly changing. Variable transmission ratio can be achieved. According to the characteristics of the non-circular gear, the pitch curve was designed and the non-circular gear was modeled by Pro/E.
