NON-ROTATING FLEXURE BEARINGS WITH ENHANCED DYNAMIC STABILITY FOR CRYOCOOLERS AND OTHER DEVICES

A system (100) includes a device (102), a support structure (112), and a flexure bearing (200, 400, 500) configured to connect the device to the support structure. The flexure bearing includes an outer hub (202, 402, 502) and an inner hub (204, 404, 504), where the hubs are configured to be secured to the support structure and to the device. The flexure bearing also includes multiple sets (208a-208c, 408a-408c, 508a-508c) of flexure arms (210a-210b, 410a-410b, 510a-510b) connecting the outer hub and the inner hub, where each set of flexure arms includes symmetric flexure arms. The flexure bearing further includes multiple bridges (214, 414, 514a-514b), where each bridge connects one of the flexure arms in one set of flexure arms to one of the flexure arms in an adjacent set of flexure arms. La présente invention concerne un système (100) comprenant un dispositif (102), une structure de support (112) et un palier flexible (200, 400, 500) conçu pour raccorder le dispositif à la structure de support. Le palier flexible comprend un moyeu externe (202, 402, 502) et un moyeu interne (204, 404, 504), les moyeux étant conçus pour être fixés à la structure de support et au dispositif. Le palier flexible comprend également de multiples ensembles (208a-208c, 408a-408c, 508a-508c) de bras flexibles (210a-210b, 410a-410b, 510a-510b) raccordant le moyeu externe et le moyeu interne, chaque ensemble de bras flexibles comprenant des bras flexibles symétriques. Le palier flexible comprend en outre de multiples ponts (214, 414, 514a-514b), chaque pont raccordant l'un des bras flexibles dans un ensemble de bras flexibles à l'un des bras flexibles dans un ensemble adjacent de bras flexibles.
