The invention relates to a transmission with torque division for a helicopter rotor drive. In a manner known per se, in the transmission a first power transmission branch has a first rotatable driving pinion ( ) which is in constant engagement with a first toothed wheel ( ) on the output side. At least one other power transmission branch has one other driving pinion ( ) co-axial to the first driving pinion ( ) and in constant engagement with one other toothed wheel ( ) on the output side co-axial to the first toothed wheel ( ) on the output side. One torsionally elastic member is arranged in the torque flow of each power transmission branch. The torsion-resistance of the torsionally elastic members determines the load proportions of the power transmission branches. The inventive transmission makes possible a high power density with small installation space, light weight and a small number of functional elements.
