Abstract

This paper proposes a novel concept to obtain variable input speeds for a four-bar mechanism driven by an A.C. motor. In such a system, a continuously variable transmission (CVT) is proposed to use instead of an inverter-controlled motor. By this way, the speed variability which is crucial for obtaining different manufacturing and transportation processes can be provided by mechanically. Thus, more efficient system can be achieved than classical motor controlled systems since the CVT allows electrical motor to run at its nominal point in all conditions. For analyzing the dynamics of this new system, a theoretical model is established regarding that a half toroidal CVT is added between the motor and the mechanism. The simulation results associated with the systems with and without a CVT are presented by comparing to each other. The results indicate that the four-bar mechanism equipped with a CVT is feasible for the entire range of possible reduction ratios of the CVT.
