Analysis of Cycloid Drive Dynamic Behavior

Cycloid drives belong to the latest generation of planetary gear trains. Their dynamic behavior was considered in this paper. On the basis of well-know dynamic models of involute toothed gearing with external and internal toothing, a dynamic model of a single-stage cycloid drive was developed. The differential equations of system motion were written and numerically solved in the MATLAB - SIMULINK software. The system excitation force was acting in the contact of a cycloid gear tooth and a stationary central gear roller. The diagrams are obtained showing the resulting displacements, corresponding velocity and dynamic force in terms of time. .
