Split Wind Turbine Hub Segments for Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing and assembly of wind power generator hubs are challenging due to their large volume, requiring high precision and complexity, especially in connecting blade mounting parts and main shaft mounting ends.
Innovation Solution
The hub is divided into split parts along virtual planes, allowing for simpler connections using plate-shaped members and connecting members, reducing the need for flange structures and enhancing assembly precision, facilitating easier manufacturing and transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the hub is manufactured as a single large component, then structural integrity is maintained, but manufacturing and assembly difficulty increases significantly
Solution Approach 1:
The hub is divided into multiple segments along the radial direction, with each segment containing a complete circumferential section including blade mounting parts, web plates, and rim structures. This segmentation allows each segment to be manufactured separately with reduced complexity, then assembled together to form the complete hub, thereby improving manufacturing ease while maintaining structural integrity through precise connecting structures between segments
2Ease of manufacture
If the hub is divided into multiple segments, then manufacturing and assembly ease improves, but connection complexity between segments increases
Solution Approach 1:
The connecting structure integrates multiple functions into a unified design: the web plate connecting structure combines radial connection, circumferential positioning, and load transmission functions; the rim connecting structure integrates flange connections with bolt fastening systems. This merging of functions reduces the number of separate connection components needed, simplifying the overall connection structure while ensuring secure assembly between segments
3Ease of manufacture
If traditional flange structures are used for connecting segments, then connection strength is sufficient, but the structure becomes more complex and assembly more difficult
Solution Approach 1:
The design extracts and eliminates traditional complex flange structures from the hub segment connections. Instead, it uses simplified web plate connecting structures and rim connecting structures that directly join segments without requiring large external flanges. This extraction reduces assembly complexity and simplifies the overall structure while maintaining adequate connection strength through optimized joining geometries and fastening systems
