齿轮箱，发电风力发电系统和发电系统的内部润滑

Internal lubrication for a gearbox, a power-generating wind turbine system, and a power-generating system
Abstract:
A gearbox including a gear-train including an input and an output and a rotating conduit internally traversing the gear-train is provided. The rotating conduit is configured to receive lubrication fluid from one or more components downstream of the rotating conduit and deliver lubrication fluid to one or more components upstream of the rotating conduit. The components downstream of the rotating conduit rotate at a different speed than components upstream of the rotating conduit.
Abstract(Chinese):

提供了包括齿轮系的齿轮箱，其包括输入和输出以及内部横穿齿轮系的旋转导管。 旋转管道构造成从旋转管道下游的一个或多个部件接收润滑流体，并将润滑流体输送到旋转管道上游的一个或多个部件。 旋转管道下游的部件以与旋转管道上游的部件不同的速度旋转。
