In the design of planar link mechanisms, moving links are arranged in parallel offset planes in order to avoid their mutual interferences. Therefore, not only the input moment, the transmitted force and the output moment but also bending and torsional moments in planes containing moving links (motion planes) act on each links. Moving links and pairing elements of the revolute pair are deformed and the links deviate from their theoretical hi_orion planes, so the performance of the link mechanism remarkably decreases. In this paper, a new method is presented for a three dimensional static analysis of planar offset four-link mechanisms and the torsional rigidity about the revolute axis of the driving link is calculated by this method. Consequently, it is possible to evaluate deviations of driving, coupler and driven links perpendicular to their theoretical motion planes.
