Compressor Piston Ring Composite for Abrasive Wear Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compressors face issues with wear resistance due to hard fillers falling off the sliding materials, leading to abrasive action and wear.
Innovation Solution
Incorporating a resin member with metal particles having a surface layer with affinity to the resin, which enhances adhesion and reduces wear by dispersing metal particles within the resin member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hard filler is added to sliding material to improve wear resistance, then wear resistance is improved, but the hard filler falls off and causes abrasive wear
Solution Approach 1:
The invention uses a composite material structure consisting of a resin base material and dispersed metal particles. The metal particles provide wear resistance while the resin matrix holds them firmly in place, preventing them from falling off and causing abrasive wear. This composite structure resolves the contradiction by combining the advantages of both materials while mitigating their individual disadvantages.
2Reliability
If metal particles are dispersed in resin member, then adhesion is enhanced and wear is reduced, but manufacturing complexity increases
Solution Approach 1:
The invention controls the particle size, shape, and distribution parameters of the metal particles within specific ranges to optimize adhesion while maintaining manufacturability. By carefully selecting and controlling these parameters, the invention achieves strong adhesion without requiring overly complex manufacturing processes.
