Description
BACKGROUND OF THE
Wind turbines such as wind turbines are an environmentally friendly power generation facility that converts wind-induced rotational energy into electrical energy. It is part of a renewable energy business, which is well received in today's world where the need for global environmental protection is highlighted.
These wind turbines can be roughly divided into nacelle and tower. The nacelle includes a plurality of blades, hubs, rotors, generators, various sensors, and yaw brake devices.
The plurality of blades are integrally coupled to each other at a predetermined interval in a circumferential direction around the hub, the center of the hub is connected to the drive shaft of the rotor, and the drive shaft is connected to the generator.
When the plurality of blades are rotated by the wind, the hub equipped with the plurality of blades rotates together, and the drive shaft of the rotor rotates to drive the generator to convert rotational energy of wind into electric energy. The electric energy is transmitted to the power system through the power cable connected to the generator.
On the other hand, the wind turbine is configured such that the nacelle performs a 'yawing motion' and rotates correspondingly to the change of the wind direction to generate maximum output at all times. Such a system is called a "yaw system".
1A, a conventional yaw system includes a yaw bearing 3 having a rack gear 3a arranged in a circumferential direction on an upper portion of a
When the wind direction changes, the yaw drive 4 performs yawing motion along the yaw bearing 3 in order to move the plurality of blades in the wind-blowing direction.
However, when the

These yaw brakes are pre-coupled to the bottom of the nacelle before the nacelle is mounted on the tower of the wind turbine. The
However, in the
As a result, a falling accident occurs in the process of moving the brakes B to the nacelle, and the weight weight is also not stably fixed. Further, when the
