Abstract: The Galloway mechanism is a plane four-bar, drag-link-type linkage with one pair of equal-length shorter links, and one pair of equal-length longer links, forming a rhomboid geometry. The short links constitute the frame and the input links. In a Galloway mechanism, two full rotations of the input link result in a single rotation of the output link. In this paper, the Galloway mechanism is analyzed and the rules governing its motion are found. The conditions necessary for the existence of a Galloway-type spatial mechanism are then determined. As an example, the necessary relationships between the geometric parameters of a spatial RRRSR mechanism are derived. A numerical example is included.
