In the present work, a study has been conducted on the possible kinematic configurations of a given gear mechanism with intermeshing satellites to compare the values of the transmitted torques. As a result of this analysis, principal schemes of compound epicyclic gear mechanisms achieving high values of transmitted torques at the output have been proposed. Kinematic synthesis of the mechanisms with optimal gear ratios achieving the highest values of output torques has been performed.

This study presents an in-depth kinematic and dynamic analysis of an epicyclic gear mechanism with mutually engaged satellites, aiming to optimize its characteristics and overall efficiency. The primary objective is to analyze its operational performance and propose optimization solutions to enhance its effectiveness. The research focuses on the complex interactions between the satellites, which ensure even load distribution, reduce localized stresses, and increase load capacity. Key parameters of the gears, including the shape of the involute profile, have been analyzed to minimize wear and extend the service life of the mechanism. Mathematical models based on the finite element method (FEM) were utilized to conduct simulations that illustrate the impact of various loads and operating conditions on the mechanism's durability and performance. Additionally, simulations conducted in the CAD environment of SolidWorks allowed for the optimization of the gear design and other system components, achieving significant efficiency under high-load operating conditions. The results indicate that this type of mechanism is particularly suitable for applications in industries such as automotive engineering, aerospace technology, and the energy sector, where reliability, durability, and precision in operational processes are of critical importance.
