Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine rotor core production, in particular to a combined grinding device for processing wind turbine rotor cores. Background Art

[0002] The modular design of the wind turbine rotor core has many benefits: 1) This design can significantly improve the efficiency of the rotor. As one of the core components of the generator rotor, the rotor core is made of high-quality core materials. Its modular structure helps to transfer and convert energy more efficiently, thereby improving the overall power generation efficiency. 2) The modular design makes the manufacture and maintenance of the rotor core more convenient. Since each part can be manufactured and assembled separately, this reduces the manufacturing difficulty and cost, and also facilitates later maintenance and replacement. When a part has a problem, only that part can be repaired or replaced without large-scale disassembly and maintenance of the entire rotor core. 3) The modular rotor core also has good thermal and mechanical properties. Due to the reduced contact area between the parts, the heat dissipation performance is improved, which helps to reduce the heat generated by the rotor during operation, thereby improving its operating stability and reliability. At the same time, the design of the modular structure can also better adapt to the mechanical stress and deformation that may occur in the rotor during operation. 4) From the perspective of environmental protection and sustainable development, the design of the modular rotor core also has its advantages. Since each part can be recycled and processed separately, this is conducive to the recycling of resources and reducing environmental pollution.
