ABSTRACT:
A substantially flat, steel ring having an axis, has an axial end face with two parallel chordal grooves disposed symmetrically about a central aperture. A flat end surface between the chordal grooves engages an adjacent planet gear and ends of rollers supporting the planet gear. A portion of the chordal grooves is radially inward of the outer raceway of the rollers, providing a lubricant path between the planet washer and the planet gear.
