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.
