Reliability Model for Planetary Gear Trains

Journal of Mechanisms, Transmissions, and Automation in Design, 1983
A reliability model is presented for planetary gear trains in which the ring gear is fixed, the sun gear is the input, and the planet arm is the output. The input and output shafts are coaxial and the input and output torques are assumed to be coaxial with these shafts. Thrust and side loading are neglected.

Topological Synthesis of Planetary Gear Trains

Applied Mechanics and Materials, 2010
Application 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.

Planetary Gear Train Dynamics

Journal of Mechanical Design, 1994
A model to simulate the dynamic behavior of a single-stage planetary gear train with helical gears is developed. The three-dimensional dynamic model includes all six rigid body motions of the gears and the carrier. The generic nature of the formulation allows the analysis of a planetary gear set with any number of planets.

Gear Trains and Planetary Gears

2020
In this chapter, the general concepts of ordinary gear trains are first described, particularly those concerning their efficiency and the obtainable transmission ratios. The same concepts are then extended to planetary gear trains and various methods of calculating the transmissions ratios achievable with these types of gear drives are defined.

Planetary gear train for robotics

IEEE International Conference on Mechatronics, 2005. ICM '05., 2005
A 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
