Analysis of cycloid drive dynamic behavior

Abstract

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. .
