Problems solved by technology

The disadvantage of this scheme is that special tooling is necessary, the cost is high, and different bearings need to be equipped with different tooling
[0004] It can be seen that there are obvious deficiencies and defects in the structure and use of the assembly tooling of the large bearing of the generator in the prior art, and further improvement is urgently needed

Embodiment Construction

[0020] see figure 1 , figure 2 As shown, the bearing and main shaft assembly tool of the permanent magnet direct drive wind power generator of the present invention includes a base plate, a positioning plate, and a support body whose lower end is fixedly connected to the base plate and whose upper end is fixedly connected to the positioning plate.

[0021] More specifically, the bottom plate 1 preferably has an arc-shaped outer edge, and more than two installation through holes are symmetrically provided at both ends of the arc. The support body includes a pair of side plates 2 and a support plate 3 fixed between the two side plates 2, and the overall height of the support body is adapted to the axial position of the bearing to be assembled. The positioning plate includes upper and lower single-side arc plates, wherein the arc edges of the upper and lower single-side arc plates are all facing the inside of the assembly tool, and the upper single-side arc plate 4 is located a...

Abstract

The invention relates to an assembling tool for a bearing and a main shaft of a permanent magnet direct-driven wind driven generator, which comprises a bottom plate, a positioning plate and a supporting body, wherein the lower end of the supporting body is fixedly connected with the bottom plate and the upper end of the supporting body is fixedly connected with the positioning plate. The assembling tool is applied to assembly between a spherical self-aligning roller bearing, an adjusting sleeve and the main shaft of the large permanent magnet direct-driven wind driven generator, and can provide positioning to assemble the bearing to an appointed position of the main shaft and obtain an appropriate bearing play. The tool is simple in structure, low in manufacturing cost, simple to use and beneficial to adjustment, and can ensure the demands of assembly effectively to meet the technical effect needed.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a bearing and main shaft assembly tool for a permanent magnet direct drive wind power generator. Background technique [0002] At present, the generators for wind power generation are developing in the direction of high reliability, low maintenance, low cost and high efficiency. Direct drive permanent magnet wind turbines based on variable speed operation, variable pitch adjustment, low speed, high efficiency, and high power factor have become the future development trend. However, because the direct-drive permanent magnet wind turbine is directly connected to the wind turbine, its speed is low, the number of poles is large, and the size of the stator, rotor, and bearing is large, which brings about assembly problems of large motors that cannot be ignored. [0003] For large bearings with adjustable clearance, they are generally assembled with special hydraulic too...
