Split-Sleeve Foil Bearing Assembly for Easier Manufacturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing manufacturing processes for film bearings with a storage sleeve are labor-intensive due to the complex connection of sub-bodies, requiring significant effort and tools for assembly and processing.
Innovation Solution
The storage sleeve is designed with axial dividing lines that allow it to be easily separated into two sub-bodies, which can be processed and reassembled, with features like notches and axial grooves for film fixation, simplifying the assembly and processing by allowing for welding and the use of an assembly aid device for film installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the storage sleeve is made as a one-piece structure, then the structural integrity is improved, but the manufacturing complexity and difficulty of processing increases
Solution Approach 1:
The storage sleeve is divided into multiple separable sub-bodies connected by dividing lines. This allows each sub-body to be manufactured and processed independently with simpler tools, while the dividing lines ensure proper alignment and reassembly to maintain structural integrity of the complete storage sleeve.
2Ease of manufacture
If the storage sleeve is divided into multiple sub-bodies, then the ease of manufacture and handling is improved, but the assembly complexity increases
Solution Approach 1:
Dividing lines are pre-marked on the storage sleeve before separation into sub-bodies. These dividing lines serve as guides for reassembly, ensuring that sub-bodies are correctly aligned and positioned during assembly, thereby reducing assembly complexity despite the multi-component structure.
3Ease of manufacture
If fracture force is applied to separate the storage sleeve, then the separation process is simplified, but the risk of uncontrolled breaking increases
Solution Approach 1:
The storage sleeve is designed with predetermined dividing lines that segment the structure into manageable sub-bodies. These dividing lines act as controlled weak points that guide the fracture force to specific locations, enabling clean separation while maintaining precision and control over the breaking process.
