Based on the theoretical background, this paper presents a design of a crank-rocker mechanism, which is also known as extreme case of the four-bar linkage. This is very common mechanism used for stone crushing in the practice. Initial functional design is performed by the method of geometric synthesis in combination with analytical calculations. The most common problem associated with the synthesis of the crank-rocker mechanism is that of designing the linkage for a given oscillation angle and a given time ratio. To improve the efficiency of the device is performed the sensitivity analysis in the MSC.ADAMS with the goal to refine the designed geometric parameters.
