<p>An isolated ring gear (60) for a planetary gear drive system (12), which isolated ring gear (60) is operative transferring torque loads and reducing the transmission of high frequency vibrations from the planetary pinions (36). The isolated ring gear (60) includes an inner ring segment (62), an outer ring segment (64) and a plurality of spring elements (66) disposed between and integrally formed with the inner and outer ring segments (62, 64). The inner ring segment (62) has a plurality of gear teeth (62T) for being disposed in intermeshing combination with the teeth (32bT) of the planetary pinions (36) and the outer ring segment (64) is rigidly affixed to the adjacent support structure. The spring elements (66) are operative to transfer torque loads from the inner ring segment (62) to the outer ring segment (64) and, furthermore, provide a torsionally soft load path for reducing the transmission of high frequency vibrations from the inner ring segment (62) to the adjacent support structure.</p> |
