The Mechanical Efficiency of Epicyclic Gear Trains
Journal of Mechanical Design, 1993The analysis of mechanical efficiency constitutes an important phase in the design analysis of gear drives. The objective of this investigation has been the development of a general algorithm for the determination of efficiency in split-power spur-gear trains.

Mechanics of Epicyclic Bevel-Gear Trains
Journal of Engineering for Industry, 1973The kinematics, statics, and inertia-force analysis of epicyclic bevel-gear trains have been described. Beginning with the general case of nonparallel, nonintersecting axes, the results are specialized to planetary bevel-gear trains. Dual (3 × 3) matrices have been found useful in the analysis, which is an outgrowth of earlier work on spur-gear trains.

Flow graphs and epicyclic gear trains
IEEE Transactions on Automatic Control, 1971Coates flow graphs and Chan-Mai graphs have been applied to the analysis of epicyclic gear trains. They are found to be superior to signal flow graph analysis because their gain formulas are simpler and require a lesser number of expansions to yield the desired result.

Epicyclic gear trains for automotive automatic transmissions
Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering, 2000Epicyclic gear trains, which contain at least four coaxial links, are widely used in automatic transmissions. This paper presents a systematic methodology for the synthesis of epicyclic gear trains for automotive automatic transmissions. The graph representation of epicyclic gear trains is applied to develop an approach for the structural synthesis of

Epicyclic gear trains for difficult ratios
Journal of Scientific Instruments, 1941This paper is complementary to one by Clay* in which he made use of the continued fraction, whereas in this paper the wide capacity of the epicyclic train is employed in each case for finding wheelwork to give ratios which appear almost unattainable. After giving an example of an epicyclic train, the author explains the principle of their action.

CENTRALISED LUBRICATION BY USING EPICYCLIC GEAR TRAIN
2022In many industrial applications it is required to drive the actuators, hydraulic cylinders at variable speed this is only possible by variable discharge from a variable displacement pump so it is not feasible to use it. One method employed is to use a pump of higher discharge capacity, but higher capacity means higher cost and higher power consumption ...
