Abstract
Multiple pinion concentric drive with a gear of large diameter fixed on a driven shaft having disposed before each drive pinion and connected thereto a rotatable drive gearing unit which in turn is connected with a distributor gearing for driving the rotatable drive gearing unit, which latter has an outer concentric wheel pivoting on its bearing support and its reaction moment acting against an elastic member such as a hydraulic piston cylinder unit. The elastic support of the reaction moments of outer concentric wheels has among other advantages, the advantage that no reaction moments of different magnitude can occur and thus all transmitted power components in the individual power branches driving each drive pinion are of equal magnitude.
Claims10
Multiple pinion concentric drive having a plurality of pinions meshing with a main gear fixed on a driven shaft, the main gear having a diameter larger than that of the pinions, comprising a respective rotatable gearing unit preceding and connected to the pinions for driving said pinions, the rotatable gearing units being connected to and driven by a distributor gearing, said rotatable gearing units having a respective outer concentric gear rotatably mounted thereon, and an elastic member for each of said rotatable gearing units respectively connected to said outer concentric gear so that the reaction moment of said outer concentric gear acts against said elastic member, and is damped by said elastic member whereby a uniform turning moment distribution is effected.
