ABSTRACT:
A rotary flexure is designed to exhibit very high radial and axial stiffness and to exhibit virtually no movement in its center of rotation. The flexure, which is formed from a single billet of material, includes an outer ring from which three thin flexure blades extend. The flexure blades extend toward the centerpoint of the rotary flexure, where they join to form a centerpiece. Three lobes also join at the centerpiece, one between each pair of flexure blades. The lobes extend toward the outer ring, and are free to rotate about the pivot axis with respect to the outer ring and the flexure blades. During rotation, the pivot axis exhibits virtually no movement.
