Reactor Outer Iron Core Assembly Gap Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Reactors with outer peripheral iron core portions face challenges in maintaining desired gap dimensions between iron core coils, leading to inconsistent inductance and requiring special jigs for accurate assembly.
Innovation Solution
A reactor design featuring a core body with an outer peripheral iron core composed of multiple portions, where fasteners on an end plate secure the iron core portions, allowing for consistent gap maintenance without the need for special jigs, thereby enhancing assembly efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If outer peripheral iron core portions are assembled without special jigs, then assembly efficiency increases, but gap dimension precision deteriorates
Solution Approach 1:
The end plate is designed with fastener holes positioned at predetermined locations before assembly. The fasteners are inserted through these pre-positioned holes to directly secure the outer peripheral iron core portions, eliminating the need for special jigs during assembly while ensuring consistent gap dimensions.
2Manufacturing precision
If special jigs are used to maintain gap dimensions, then manufacturing precision improves, but device complexity and production cost increase
Solution Approach 1:
The function of maintaining gap dimensions is extracted from the assembly process and embedded into the end plate structure itself. The fastener holes in the end plate are positioned to automatically maintain the desired gap dimensions when fasteners are installed, eliminating the need for separate special jigs.
3Ease of operation
If outer peripheral iron core portions are misaligned, then assembly ease improves, but inductance reliability deteriorates
Solution Approach 1:
The end plate serves as an intermediary component that mediates between the outer peripheral iron core portions. The fastener holes in the end plate are positioned to guide the iron core portions into correct alignment, ensuring both ease of assembly and reliable inductance through proper positioning.
