Patent attributes
An epicyclic gear train includes a sun gear and planet gears mounted to a carrier and engaged to the sun gear. The planet gears and the carrier are rotatable about a center axis, and the carrier is engaged with a power output at a carrier-output engagement location. Ring gears are in meshed engagement with the planet gears. Planet gear bearings are disposed between one of the planet gears and the carrier. A lubrication interface is defined between each planet gear bearing and one of the planet gears. A bearing lubrication system includes a lubricant supply conduit extending between a conduit inlet at the carrier-output engagement location and conduit outlets at the lubrication interfaces of the planet gear bearings. A lubricant strainer is mounted about the conduit inlet at the carrier-output engagement location.
