PLANETARY GEAR
In mechanical gears, changes in the speed of rotation are effected by external switching. In a planetary gear, a plurality of transfer pinion systems (A, B, C, 18, 19) are combined with each other in such a way that a division of the torque to be transmitted is obtained. This division makes it possible to accelerate the power take-off from standstill to the speed of rotation corresponding to the resisting torque at constant engine torque. The drive adjusts itself automatically to the correct speed of rotation and is protected against overloading.
