Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing multi-layer plain bearings are complex and expensive, lacking a simplified approach for achieving a strong and stable connection between the bearing body and the carrier body.
Innovation Solution
A method involving a carrier body with a surface structure formed by left-right knurling, where the bearing body is pressed onto the carrier body, creating a positive connection through plastic deformation, allowing for a strong and durable bond using techniques such as turning tools, laser processing, or 3D printing, and optionally assisted by magnetic forces or thermal treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If complex manufacturing methods are used to produce multi-layer plain bearings, then connection strength between bearing body and carrier body is improved, but manufacturing cost and process complexity increase
Solution Approach 1:
A surface structure is formed on the carrier body connection surface before the bearing body is applied. This preliminary action creates a pre-prepared interface that enables strong connection through subsequent simple pressing, avoiding complex multi-step manufacturing processes while ensuring high connection strength between the bearing body and carrier body.
2Ease of manufacture
If simple pressing is used to join bearing body to carrier body, then manufacturing ease is improved, but connection durability deteriorates
Solution Approach 1:
A surface structure with varying local geometries (ridges, valleys, undercuts) is created on the carrier body connection surface. This local quality variation enables the bearing body material to be plastically deformed into specific regions during pressing, creating mechanical interlocking that significantly enhances connection durability while maintaining the simplicity of the pressing operation.
3Adaptability or versatility
If bearing body strength is made lower than carrier body strength, then adaptability of bearing body material is improved, but structural integrity may be compromised
Solution Approach 1:
The surface structure is formed on the carrier body before assembly, creating a mechanical interlocking interface that compensates for the lower strength of the bearing body material. This preliminary preparation allows softer, more adaptable bearing materials to achieve strong connections through plastic deformation into the surface structure, maintaining both material versatility and structural integrity.
