Classification and Synthesis of Planetary Gear Trains
Volume 5b: Power Transmission and Gearing Conference, 2005Application of topological graphs to analyze and synthesize planetary gear trains (PGTs) is an effective approach in searching for innovative planetary trains. A new graph representation and stratification standard are introduced firstly. Then three topological graphs of basic structure and four fundamental units (FUs) of PGTs are established as the ...

Displacement isomorphism of planetary gear trains
Mechanism and Machine Theory, 1994Abstract This paper presents an efficient method for the identification of the displacement isomorphism of planetary gear trains with any number of gear pairs. For every plantary gear train, the corresponding displacement graph and rotation graph are used to characterize its kinematic structure.

Topological Synthesis of Planetary Gear Trains
Applied Mechanics and Materials, 2010Application of topological graphs to analyze and synthesize planetary gear trains (PGTs) is an effective approach in searching for innovative planetary trains. Two topological graphs of basic structure and three fundamental units of PGTs are established as the basis of topological synthesis.

The Homotopy Analysis for the Nonlinear Dynamics of Planetary Gear Trains
Volume 6: 14th International Conference on Multibody Systems, Nonlinear Dynamics, and Control, 2018In this paper, the homotopy analysis method (HAM) is proposed to study the nonlinear oscillators of planetary gear trains, in which the periodically time-varying mesh stiffness and gear backlash are included through a nonlinear displacement function. In contrast to the traditional perturbation methods, the HAM does not require a small parameter in the ...

Modelling and control of cam-controlled planetary gear trains
International Journal of Modelling, Identification and Control, 2011This work aims to perform the modelling and the motion control of cam-controlled planetary gear trains, such that their output motions can be fairly agreed with the required. First, the semi-closed-loop control is employed as the system architecture. Then the transfer functions of the motor with and without loading are established.

Structure and analysis of planetary gear trains
Journal of Mechanisms, 1968Abstract Both compound and internal or external planet gears are considered as well as the paired planet gears. It is stated that the simple planetary gear train consisting of two central gears, one or more planet gears and one arm, has 34 different types. All 34 types can be derived from one general form of the simple planetary gear train.
