This article presents results of the numerical analysis of cycloidal gearbox, which were obtained in MSC Adams engineering software. Multibody geometry for dynamical analysis was designed in Autodesk Inventor Professional 2017 and imported in MSC Adams. The results of analysis are forces acting on the internal and external sleeves, position, velocity and acceleration of the selected points on the cycloidal gearbox’s moving components. Indirect result is time course of the torque at output shaft which was calculated on the basis of forces acting on the internal sleeves, which are parts of the equilibrium mechanism and displacements of these sleeves. Knowledge about cycloidal gearbox’s loading conditions is important in its design process. Main advantage of a cycloidal gearbox is distribution of the forces on multiple external sleeves, while in majority of other gears only one tooth is in contact at a time.
