Abstract: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 calcu… Show more

The article discusses the problem of a torque ripple on the output shaft of a cycloidal gearbox. To investigate the phenomenon, numerical simulations were performed and compared with the experimental results. Simulations were performed with multibody dynamic software—one with rigid and second with flexible elements. The dynamic model of the gearbox for the determination of the amplitude of the torque change was introduced, where the model utilizes periodical change of the stiffness of gear components as well as geometrical parameters, which are the results of machining and assembly tolerances. The test was made on a gearbox that was calculated, designed, and tested by the authors of the article. To perform the test, a test bench was built. The bench included electric motors, torque meters, and a control application.

“…The works [4] and [5] present kinematic analysis of the cycloidal gearbox. There is an incorrect conclusion in [5], where it is stated that the torque fluctuation at the input shaft does not significantly influence output. In the current article, it will be shown that torque fluctuation at the output shaft is close to the result of the input torque fluctuation multiplied by the gear ratio (Fig.…”
