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.
