Abstract
A flexure mount particularly adapted for use in a dynamically tuned gyroscope provides a universal coupling between a rotor element and a drive shaft. The mount features a substantially planar "spider" member oriented transversely to the spin axis of the rotor. The spider has four webs that each extend radially from an inner gimbal ring to a segmented outer ring having four independent sectors each associated with and centered on one of the webs. Two mutually perpendicular "vertical" or cross flexure members each have key portions that extend through radial slots in the webs of the spider. The inner gimbal ring and the spider have central apertures coaxial with the spin axis. An alignment member is seated in the aligned apertures. The vertical flexure members are seated in a set of mutually perpendicular and axially extending slots formed in the alignment member. The spider and the cross members are preferably etched or stamped from precision rolled sheet material. In the preferred form, the inner gimbal ring and the outer mounting 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…
