US Patent 9772027 Variable baffle that reduces oil at the gear mesh

A variable baffle for controlling a flow of oil at a gear mesh includes a first baffle member fixed proximate to the gear teeth of a first rotating gear. A second baffle member is rotatably connected to the first baffle member. A third baffle member is fixed proximate to a second rotating gear and aligned with the second baffle member when the second baffle member is in a closed position. A rotating member rotatably connects the second baffle member to the first baffle member. The second baffle member is movable away from the closed position to an open position when the force of a fluid expelled from the gear teeth of the first rotating gear exceeds a force applied to the rotating member normally acting to move the second baffle member toward the closed position.
