Abstract:
A gearwheel for a planetary gear train includes two working toothing regions arranged successively in direction of a gearwheel rotational axis (Z). A first working toothing region is arranged at a first gearwheel part, and a second working toothing region is arranged at a second gearwheel part. The two gearwheel parts are connected to one another by positive engagement and/or bonding engagement and/or frictional engagement so as to rotate together around the gearwheel rotational axis (Z) and/or against relative movement with respect to one another in direction of the gearwheel rotational axis (Z).
