RENEWABLE ENERGY-TYPE POWER GENERATOR

摘要

A renewable energy power generating apparatus includes: at least one blade; a hub to which the at least one blade is mounted; a cylindrical member extending through the hub and in a direction orthogonal to a rotational plane of a rotor including the at least one blade and the hub; at least one main bearing disposed between the hub and the cylindrical member, the at least one main bearing rotatably supporting the hub on the cylindrical member; a nacelle including a nacelle base plate supporting the cylindrical member; a hydraulic pump including a rotor part fixed to the hub and a stator part fixed to the cylindrical member, the rotor part and the stator part being disposed on an opposite side of the hub from the nacelle and; a hydraulic motor configured to be driven by pressurized oil from the hydraulic pump; an oil pipe disposed between the hydraulic pump and the hydraulic motor so as to be inserted through the cylindrical member; and a generator configured to be driven by the hydraulic motor.
