    Abstract

    Spherical flexure joints with three degrees of freedom are typically limited to small deflections, because when deflected they lose a great deal of stiffness in support directions. To allow for a larger range of motion while maintaining high support stiffness, an advanced stacked folded-leafspring-based spherical joint has been developed. Optimisations of this design have led to a spherical joint with a 30° range of tilt motion in combination with a high support stiffness (> 200 N/mm) and load capacity (> 290 N).
