Abstract
Description
Technical Field
[0001] The utility model relates to a positioning and guiding device for a stator cover base of a wind generator, in particular to a positioning and guiding device for a stator cover base of a wind generator, and belongs to the technical field of stator cover bases of wind generators. Background Art
[0002] A wind turbine is an electric device that converts wind energy into mechanical work, which drives the rotor to rotate and finally outputs alternating current. Its working principle is relatively simple. The wind wheel rotates under the action of wind force, which converts the kinetic energy of the wind into the mechanical energy of the wind wheel shaft. The generator rotates and generates electricity under the drive of the wind wheel shaft. The stator of the wind turbine includes an iron core, a coil embedded in the iron core, and a base outside the iron core. During installation, it is necessary to ensure that the iron core embedded in the coil is aligned with the 12 o'clock direction of the stator sleeve base, and then insert the iron core into the base.
[0003] When inserting the existing iron core into the stator sleeve base, the bottom end of the iron core is usually aligned with the bottom end of the base by visual inspection, and then the iron core is vertically inserted into the base. Since the installation of the iron core and the base is an interference fit, the iron core cannot be guided correctly during the insertion of the iron core into the base, and may be skewed, making it difficult to insert the iron core into the base. At the same time, the skewness of the iron core may cause deviation, making it impossible to ensure that the iron core and the base are aligned at the 12 o'clock direction. Utility Model Content
