The invention relates to an aerogenerator, in particular to a main shaft of the aerogenerator. According to the technical proposal provided by the invention, the main shaft is provided with a bearingsupport, and a radial bearing is used to connect the main shaft and the bearing support. The invention is characterized in that: the main shaft is provided with a left step and a right step; an outerdiameter d1 of the left step is larger than a diameter d2 of the right step; the main shaft corresponding to the left step and the main shaft corresponding to the right step are respectively providedwith the radial bearing and the bearing support thereof; the left end and the right end of each bearing support are respectively provided with a left end closure and a right end closure; a left retainer ring and a right retainer ring are respectively arranged between the left end closure and the main shaft, and between the right end closure and the main shaft; and the right side of the right retainer ring is provided with a locking bolt which is in screwed connection with the main shaft and is used for locking the position of the radial bearing. The main shaft has a simple structure, and is beneficial to manufacture and maintenance.
Description
technical field [0001] The invention relates to a wind power generator, in particular to a main shaft of a wind power generator. Background technique [0002] The main shaft of the wind power generator is the main part of the wind power generator. On the main shaft of the wind power generator, some components related to the blades and bearings for fixing the main shaft need to be installed. The main shaft of the wind turbine works under high-altitude field conditions, and it is difficult to maintain and maintain it. However, due to the unreasonable structure of the traditional main shaft, it is more difficult to operate in terms of maintenance. Contents of the invention [0003] The purpose of the present invention is to design a main shaft of a wind power generator, which has a relatively simple structure and is helpful for manufacture and maintenance. [0004] According to the technical solution provided by the present invention, there is a bearing seat on the main shaf...
