A flexure mount assembly particularly adapted for use in a dynamically tuned two-degree-of-freedom gyroscope to provide a universal coupling between a rotor element and a drive shaft. The mount features a substantially planar "spider" member normally oriented transversely to the spin axis of the rotor. The spider has four webs, each web extending radially from an inner central area associated with an inner gimbal ring to an outer annular area. The outer annular area is associated with an outer ring which is divided into four independent sectors. Each web has two sections and each section has the shape of two parabolas which intersect at their vertices. A central aperture roughly elliptical in shape is thus formed in each web. At both ends of each aperture, narrow radial slots are formed. Two mutually perpendicular "vertical" or cross flexure members each have key portions that extend in planes parallel to the spin axis through the radial slots. The inner gimbal ring and the spider have aligned central apertures coaxial with the spin axis which accommodate an alignment member. The vertical flexure members are seated in a set of mutually perpendicular and axially extending slots formed in the alignment member. The inner gimbal ring and the outer ring are formed by substantially identical upper and lower halves which sandwich the spider. The halves each have a set of radially aligned slots formed in their opposed faces to receive the vertical cross members. |
