Embodiment Construction
[0010] The arc-shaped wheel rim (1), wheel spoke (2) and wheel hub (3) are respectively manufactured by using medium-carbon steel or low-carbon steel plate materials of the same brand. The welding method is spliced, and fan-shaped holes (4) are uniformly opened in the plane of the spokes, and then the above-mentioned components are welded together through welding seams (5).

The invention relates to a structure of a large-scale flywheel blank and a manufacturing method. In the structure, a rim, a spoke and a hub are made of a medium carbon steel or low-carbon steel plate material which is of the same brand, wherein the rim is formed by splicing circular arcs which are rolled by multiple sections of steel plates by a welding method; fan-shaped holes are formed in a plane of the spoke uniformly; and the components are welded by a welding method to overcome the defect of welding quality in a structure of the conventional large-scale flywheel blank and a manufacturing method and the defect that weld joints are easy to crack. Simultaneously, compared with the conventional structure and the manufacturing method, the structure has the advantage of low manufacturing cost.
Description
technical field [0001] The invention relates to a structure and a manufacturing method of a flywheel blank, in particular to a structure and a manufacturing method of a large flywheel blank, and belongs to the technical field of mechanical manufacturing technology. Background technique [0002] Traditionally, flywheel blanks are generally manufactured by casting, especially for large flywheel blanks, most of them are manufactured by casting. With the development of market economy, customers often need to order when purchasing mechanical products. For some special, large and non-standard products, when the enterprise organizes the production, it should also organize the production in small batches and multiple varieties according to the requirements of the market to meet the needs of the market. These products sometimes include large flywheels. If conventional The method of casting not only has the defect of long production cycle, but also has the defect of high cost in the c...
