Problems solved by technology
However, the structural strength of the above-mentioned spliced hubcaps will be limited to a large extent by the splicing mechanism of the hubcap blocks, which has fatal shortcomings; The existence of the surface will inevitably affect the dynamic performance of the surface airflow. Although the gap can be filled and polished to achieve a smooth surface curve through later repairs, it also increases the hubcap manufacturing process and corresponding costs.

Embodiment Construction
[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0038] For the integrated hubcap, since the U-shaped body of the hubcap has three cylindrical protrusions, the corresponding mold must also have three cylindrical protrusions, and once the integral casting of the integral hubcap is completed, how Getting the bulky hubcaps out of the mold was an extremely important issue. This is because the protruding part of the hubcap is horizontally embedded in the corresponding protruding part of the hubcap mould. A mold assembly whose width exceeds the maximum caliber of the cylindrical protruding part is horizontally divided at the horizontal maximum caliber to determine a horizontal splicing line, and a vertically split splicing line is determined between any two protruding parts, and the horizontal splicing An arc-shaped sp...

Abstract
The invention discloses a hubcap and a production method thereof. The hubcap comprises a U-shaped hollow thin-walled hubcap body and a first tube-shaped protrusion part, a second tube-shaped protrusion part, and a third tube-shaped protrusion part embedded at the side wall of the hubcap; the hubcap body and the first, the second, and the third tube-shaped protrusion parts are cast and connected as a whole body. By using a split-shaped splicing die and in manner of vacuum suction casting, the hubcap is made of composite material and resin after suction casting and solidification. The integral hub of the invention has the advantages of fine structure strength, smooth surface, etc.
Description
technical field [0001] The invention relates to the technical field of wind power generation equipment manufacturing, in particular to a hub cover used for wind power generation equipment and a manufacturing method thereof. Background technique [0002] With the continuous development of modern industrialization, human demand for fossil energy (such as oil, coal) is increasing day by day. The massive consumption of this non-renewable energy improves the quality of life of human beings on the one hand, but it also brings Severe problems that threaten human survival, such as energy crisis, climate warming, and environmental pollution [0003] At present, the use of renewable energy such as hydropower, solar energy, biomass energy, and wind energy is gradually being used on a large scale because it can partially replace the consumption of fossil energy. Among them, wind energy has become a hot spot in the development of new energy because of its wide distribution, large-scale ...
