Generator Rotor Asymmetrical Dividing Planes Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of transporting generators with air gap diameters exceeding 5 meters to wind power plant sites is hindered by road width limitations, necessitating disassembly into smaller parts, which leads to potential misalignment and increased assembly efforts, resulting in uneven operation and reduced precision.
Innovation Solution
A generator rotor with asymmetrical dividing planes allows for segmentation into segments of varying shapes and dimensions, enabling precise reassembly while maintaining connected bearings and form-wound coils in the stator, facilitating efficient transport and minimizing play during reassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the generator is divided into segments for transport, then the transportability is improved, but the manufacturing precision deteriorates due to play at connecting points
Solution Approach 1:
The generator rotor is divided into multiple segments along asymmetrical dividing planes, allowing each segment to be transported separately while maintaining the overall structural integrity. The asymmetrical design ensures that connecting points are strategically positioned to minimize play during reassembly.
Solution Approach 2:
Asymmetrical dividing planes are used instead of symmetrical ones, creating segments with varying shapes and dimensions. This asymmetry optimizes the positioning of connecting points and bearing openings, reducing play at junctions and improving alignment precision during reassembly at the erection site.
2Length of moving object
If the generator is disassembled for transport, then the transportability is improved, but the device complexity increases due to reassembly efforts
Solution Approach 1:
The generator is segmented into a manageable number of parts (typically two to four segments) rather than being completely disassembled. This segmentation approach maintains transportability while significantly reducing the complexity of reassembly compared to full disassembly.
Solution Approach 2:
The generator is tested and adjusted on the test bench before segmentation. All necessary adjustments and fine-tuning are performed in advance, so that reassembly at the erection site requires minimal additional work. The segments are designed to be reassembled in a predetermined sequence.
3Length of moving object
If the generator is disassembled for transport, then the transportability is improved, but the reliability deteriorates due to uneven operation after reassembly
Solution Approach 1:
The generator undergoes comprehensive testing and adjustment on the test bench before being segmented for transport. All critical operational parameters are verified and optimized in advance, ensuring that the generator's performance is established before segmentation occurs.
Solution Approach 2:
Asymmetrical dividing planes are strategically positioned to avoid critical balancing points and rotational centers. This ensures that the segments can be reassembled with minimal play at connecting points, preserving the generator's dynamic balance and operational reliability.
