A planetary pin for use in a planetary gear system, the planetary pin comprising:
- a cylindrical body having an outer surface, a first end surface at a first axial end, and a second end surface at a second axial end;
- and
- a circular groove formed in at least one of the first end surface or the second end surface, the circular groove concentric with the cylindrical body and displaced radially inwardly from the outer surface, wherein the circular groove comprises a radially inwardly sloped radial inner wall, a generally flat bottom wall perpendicular to a longitudinal axis of the planetary pin, and a radial outer wall generally parallel to the outer surface.
A planetary pin assembly comprising:
- a planetary carrier including a planetary pin receptacle and a lubricant supply passage;
- and
- a planetary pin comprising:
- a cylindrical body having an outer surface, a first end surface at a first axial end, and a second end surface at a second axial end;
- and
- a circular groove formed in at least one of the first end surface or the second end surface, the circular groove concentric with the cylindrical body and displaced radially inwardly from the outer surface,
- wherein the planetary pin is disposed in the planetary pin receptacle and fixed within the receptacle by staking, and the circular groove comprises a radially inwardly sloped radial inner wall, a generally flat bottom wall perpendicular to a longitudinal axis of the planetary pin, and a radial outer wall generally parallel to the outer surface.
