The split-torque reduction gear comprising a single input drive shaft (2) and a low-speed gear wheel (3) mounted on an output shaft parallel or orthogonal to the said input shaft and driven by at least four pinions (4, 5, 6, 7) arranged in a main casing (1), is characterised in that the four pinions (4, 5, 6, 7) are split into two identical groups of two pinions, one of the pinions (4, 6) of each group is driven by a planet-carrier of a planetary gear mechanism, and the other (5, 7) of the said pinions is driven by the external toothing of a ring gear (19a, 19b) of the said planetary gear mechanism via a gear wheel (24a, 24b), which constitutes a first power-splitting system, each of the said planetary gear mechanisms comprising a sun gear (16a, 16b) integral with an intermediate shaft, each connected to the input drive shaft (2) by a second power- splitting system. <IMAGE> |
