LUBRICATION SYSTEM OF AERO GENERATOR USING HYDRAULIC BRAKE

摘要

PURPOSE: A gearbox for a wind power generator using a hydraulic brake is provided to simply stop the rotation of multiple gears in a gearbox or change into a rotatable state depending on the situation without any request for control. CONSTITUTION: A gearbox for a wind power generator using a hydraulic brake comprises an outer gear (26) and a hydraulic brake (90). The outer gear supplies accelerating rotator power to a generator. The hydraulic brake is installed at one side of the outer gear. The hydraulic brake comprises a piston (95), multiple first disks (91), multiple second disks (92), and a pressurization spring (98). The piston operates by hydraulic pressure. The multiple first disks are depressurized by the operation of the piston. The multiple second disks are reciprocally arranged among the multiple first disks and are connected with the outer gear. The pressurization spring supplies elastic force to the piston in a direction to mutually engage the first disk and the second disk.
