Description

Technical Field

[0001] The utility model relates to a wind generator, in particular to a radial sealing pad turning fixture of the wind generator. Background Art

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and finally outputs alternating current. The wind rotor rotates under the action of wind force, converting the kinetic energy of the wind into the mechanical energy of the wind rotor shaft. The generator rotates and generates electricity under the drive of the wind rotor shaft. Since wind turbines are used outdoors, they will be exposed to rain on rainy days. Once water enters the interior, it will cause a short circuit. In order to prevent water leakage, a sealing gasket needs to be installed at the connection between the rotor and the generator.

[0003] The existing gaskets use a gasket turning fixture during the turning process. When turning the inner and outer rings of the gasket, it is necessary to first use a fixture that can clamp the inner ring, then remove the gasket, and then transfer it to a fixture that can clamp the outer ring of the gasket, which is time-consuming and labor-intensive, and reduces work efficiency.
