WIND POWER GENERATOR AND VENTILATION STRUCTURE OF A WIND POWER GENERATOR

摘要

PURPOSE: A wind power generator and a ventilating structure of a wind power generator are provided to enable air to be easily circulated in the hub and nacelle of a wind power generator by forming a ventilation structure, in which air can flow. CONSTITUTION: A wind power generator comprises a hub and nacelle(3). A rotor blade(5) is installed on the hub. A flange unit connected to the hub is formed on one side of the hub. The hub is rotatably installed on the nacelle by a main shaft with a rotating body connected to a driving unit. Air flow holes, which can move air from the inside of the hub to the inside of the nacelle, are formed on the flange unit of the main shaft. The nacelle comprises a driving unit and a generator. The driving unit transfers torque transferred from the hub. The generator generates with torque transferred from the driving unit.
