| Abstract | ||
| In this research, an Oldham coupling is used, and it has been modified to obtain new features. The modification is made on the intermediate part of the Oldham coupling and hence a kinematic model is approached, and two new applications are found. The proposed mechanism can be used as a function generator for some specific functions such as cardioid for the ratio, crank/shift=1, and the second finding as a sort of quick return mechanism. The results of the mathematical model show a good agreement with those of the cad model simulation and the related literature. | ||
