RENEWABLE ENERGY POWER GENERATION DEVICE

摘要

A renewable energy power generating apparatus (2) includes a hydraulic pump (8) including a rotor part (18), a stator part (22), and a pump bearing (24) disposed between the rotor part and the stator part; a nacelle (10) for housing at least the hydraulic pump (8); a yaw rotation bearing (28) for rotatably supporting a nacelle base plate (10A) of the nacelle (10); and at least one support part (30) for supporting the stator part (22) of the hydraulic pump (8) on the nacelle base plate (10A) of the nacelle (10). The rotor part (18) is supported to the nacelle base plate (10A) exclusively by the at least one pump bearing (24) so as to be rotatable. The at least one support part (30) is configured to support the stator part (22) on the nacelle base plate (10A) so that the hydraulic pump (8) is disposed between the hub (6) and a center axis of the yaw rotation bearing (28). The at least one support part (30) includes an access passage (32) for connecting a first space and a second space, the first space being disposed in the nacelle (10) accommodating the hydraulic pump (8), and the second space being disposed in the nacelle (10) and at an opposite side of the at least one support part (30) from the first space.
