The invention relates to a transmission shaft (32) for a planetary transmission, having a first coupling point (30) for introducing a torque and a second coupling point (52) for outputting the torque, wherein a path of a torque flow extending from the first coupling point to the second coupling point is formed and the axial portions of the path along which the torque flow flows are greater than an axial distance between the first coupling point and the second coupling point, wherein a freely oscillating shaft end is formed in a common axial subregion in which the torque flow flows on different radii in opposite axial directions. Due to the extended path of the torque flow (54), the stiffness and the natural frequency of an oscillatory overall system having the transmission shaft (32) can be reduced, thereby allowing disruptive oscillations in a planetary transmission to be reduced.
