Vibration Characteristics for Planetary Geared Systems with Plastic Gears
Applied Mechanics and Materials, 2015A torsional dynamic model and testing model for planetary geared systems are established to study the effects on its vibration characteristics as substituting plastic gears for steel ones successively. The dynamic model is solved by using variable step Runge-Kutta method and the vibration testing experiments for four kinds of combined planetary geared ...

The Analysis of Planetary Gear Trains
Volume 2: 30th Annual Mechanisms and Robotics Conference, Parts A and B, 2006The Generalized Lever is a new tool in gear train representation. It extends the traditional concept of a lever representation of a planetary gear set to one that includes negative lever ratios. This allows an exhaustive permutation of the nodes of a lever, thereby leading to all possible topological arrangements of a planetary gear train. Consequently,

Gear meshing analysis of planetary gear sets with a floating sun gear
Mechanism and Machine Theory, 2015Abstract The goal of this study is to propose an analytical approach for analysis of gear meshing in a planetary gear set with a floating sun gear. With focus on the basic geometrical relation, we derive a set of equations based on the exact involute gear geometry for calculation of the tooth clearances among engaged unmodified or modified flanks of ...

Planetary gear train for robotics
IEEE International Conference on Mechatronics, 2005. ICM '05., 2005A recursive matrix model concerning the geometric analysis, kinematics and dynamics of a Bendix wrist planetary bevel-gear train for robotics is established in this paper. The prototype of this mechanism is a three-degree-of-freedom system with seven links and four bevel gear pairs. Controlled by electric motors, three active elements of the robot have
