Pin for guiding a gear wheel, and planetary transmission containing the same

A pin for guiding a gear has a substantially cylindrical outer surface section, wherein the outer surface section comprises a substantially cylindrical rolling surface section, which is aligned and formed so as to make possible the guiding of the gear. The outer surface section further has a groove, which is formed so as to accommodate a retaining ring, wherein the groove is disposed with respect to the rolling surface section so as to make possible a guiding, directly or indirectly via the retaining ring, of a rolling-element assembly along the axial direction of the pin. In this way it is possible to provide a guiding of a gear wherein a small tolerance chain is implemented with respect to the axial position.
