Combined synthesis of five-bar linkages and non-circular gears for precise path Generation

摘要

In this paper, the integration of five-bar linkages with non-circular gears is proposed in order to synthesize a precise path generating mechanism. The proposed methodology is based on the inverse kinematic model of the linkage, whose mobility, without geared bodies, is two. Therefore, by imposing the coordinates of the coupler point at any time, the rotation of both cranks can be evaluated. A pair of non-circular gears can be then synthesized on the basis of the required I/O relationship, i.e. the relation between the two rotations, thus reducing the system's mobility. Two case studies are analyzed and presented to illustrate the synthesis procedure.
