  • System for lubricating gears in a wind turbine
    Patent number: 9528500
    Abstract: A system for lubricating gears includes a drive pinion configured to interact with bearing teeth. The drive pinion includes an internal axially extending lubricant channel connected to a plurality of radially extending lubricant delivery conduits. The plurality of radially extending lubricant delivery conduits extend from the internal axially extending lubricant channel radially outward to a radial surface of the drive pinion. The system is configured to transport lubricant from the internal lubricant channel through the plurality of lubricant delivery conduits to the radial surface to lubricate the drive pinion and the bearing teeth.
