This invention relates to a gear assembly comprising two parallel dual harmonic gears. The moment transmission ability of the gear assembly is relatively high, if the gears are interconnected and they have a common resilient rim (2) both ends of which are provided with a dual harmonic gear in such a manner that teeth (3a, 3b) on the outer surface of the rim are in meshing engagement with peripheral teeth (4a, 4b) and teeth (5a, 5b) on the inner surface in meshing engagement with shaft teeth (6a, 6b). A ring (7) positioned between the teeth serves as a primary ring from which the torsional moment is transmitted into the resilient rim through a bearing (8) and either one of the interconnected teeth in meshing engagement with the rim teeth may serve as a secondary shaft while the other remains receiving the difference between the secondary and the primary moment. |
