Patent ID: 8287389

Claim:
An arc spring damper, comprising: a plurality of circumferentially curved arc springs, wherein each circumferentially curved arc spring in the plurality of circumferentially curved arc springs includes a circumferentially curved passageway with first and second openings at first and second longitudinal ends, respectively, for said each circumferentially curved arc spring; a driving flange having a plurality of driving spring segments, each driving spring segment including a circumferentially extending driving portion; a driven flange having a plurality of driven spring segments, each driven spring segment including a circumferentially extending driven portion; and, a ring plate including a plurality of radially extending retention segments, wherein: for each said circumferentially curved arc spring a respective driving portion passes through the first opening into the passageway and a respective driven portion passes through the second opening into the passageway; and each radially extending segment from the plurality of radially extending segments is connected to a circumferentially curved arc spring from the plurality of circumferentially curved arc springs at a point between the first and second longitudinal ends, is rotatable with the circumferentially curved arc spring from the plurality of circumferentially curved arc springs, and radially restrains the circumferentially curved arc spring.
