Abstract

The invention relates to an arrangement structure for a fan yaw system. The arrangement structure comprises a yaw brake device, a yaw drive device, a connection support I and a connection support II. The yaw drive device is arranged on the part, close to the outer side, of the circumference in a cabin. The connection support I is an L-shaped outer flange and is arranged on the inner side of the yaw drive device. The vertical edge of the L-shaped outer flange and the cabin are fixed together. The lower portion of the transverse edge of the L-shaped outer flange and the yaw brake device are fixed together. The connection support II is an L-shaped inner flange. The vertical edge of the L-shaped inner flange and a tower drum are fixed together. The transverse edge of the L-shaped inner flange is a brake disc of the yaw brake device. According to the arrangement structure, the connection support I being the L-shaped outer flange and the connection support II being the L-shaped inner flange are arranged, thus the size of the cabin of a wind generating set does not need to be increased, and more yaw brake devices and yaw drive devices can be arranged in a limited space.

Description

technical field [0001] The invention relates to the field of wind power generators, in particular to an arrangement structure of a wind turbine yaw system. Background technique [0002] At present, for the sake of cost saving, the interior space of the wind turbine nacelle is relatively compact. In particular, the two components of the yaw brake device and the yaw drive device of the wind turbine yaw system are arranged on the same horizontal layer inside the nacelle. And because both require the largest driving or braking radius, in order to maximize the use of the space inside the nacelle, both are arranged as far as possible on the largest circumference radius that can be arranged in the nacelle, and more yaw drives are arranged. device, the number of yaw braking devices will be reduced, and if more yaw braking devices are arranged, the number of yaw drive devices will be reduced. When this arrangement requires a large number of yaw braking devices and yaw driving devic...
