POWER GENERATING APPARATUS OF RENEWABLE ENERGY TYPE

摘要

It is intended to provide a power generating apparatus of renewable energy type which is capable of reducing the concentrated load on the main shaft bearing and the pump housing caused by the bending of the rotating shaft and the load on the pressurized-oil piping caused by the relative displacement between the hydraulic pump and the hydraulic motor. The power generating apparatus of renewable energy type is provided with a hub rotated by the renewable energy received via a blade, a rotating shaft connected to the hub, a hydraulic pump 20 mounted on the rotating shaft and driven by rotation of the rotating shaft, a hydraulic motor 30 driven by pressurized oil from the hydraulic pump 20, a generator 35 coupled to the hydraulic motor 30, and a pressurized-oil piping 40 which is at least partially constituted of a flexible tube 43 and which connects an outlet port 24a of the hydraulic pump 20 to an inlet port 31 of the hydraulic motor 30 to supply the pressurized oil from the hydraulic pump 20 to the hydraulic motor 30, wherein the hydraulic motor is arranged lateral relative to the axis of the hydraulic pump and the generator is located between the hub and the hydraulic motor, and wherein the outlet port is arranged in the front end plate constituting an end face of the hydraulic pump located on a side facing towards the hub.
