A gear train assembly includes a first reduction planetary gear set having a rotating carrier and a second reduction planetary gear set having a non-rotating carrier. A plurality of vanes are attached to the carrier to direct oil from an oil bath towards the non-rotating carrier as the rotating carrier rotates.

Apparatus and method for lubricating a gear

A gear train assembly includes a planetary gear set partially submerged in an oil bath and having a plurality of planetary gears mounted on a rotatable carrier. A plurality of sheaths having a hydrodynamic profile are mounted on the carrier to reduce the churning and turbulence created by the planetary gears as they enter the oil bath.
