Compressor Sliding Ring Composite for Wear-Resistant Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compressors face issues with wear resistance due to hard fillers falling off the sliding material, leading to abrasive action and wear of the sliding material.
Innovation Solution
Incorporation of metal particles with a surface layer into a resin member for the sliding material, enhancing adhesion strength and wear resistance by using dendritic or spherical shapes with a coupling layer to improve the sliding material's durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hard filler is added to the sliding material to improve wear resistance, then wear resistance is improved, but the hard filler falls off during operation causing abrasive wear
Solution Approach 1:
The sliding material uses a composite structure consisting of a resin base material combined with metal particles that have a core-shell structure. The metal particles include a core material and a surface layer with different physical properties, creating a composite material that prevents filler detachment while maintaining wear resistance. This composite approach allows the hard filler to remain firmly embedded in the sliding material during operation.
2Duration of action of moving object
If hard filler is used to enhance sliding material durability, then durability is improved, but the filler detaches under stress and shear forces
Solution Approach 1:
The metal particles exhibit local quality differentiation through their core-shell structure. The core material provides one set of properties while the surface layer provides different properties, allowing the particle to maintain stability under stress and shear forces. This local differentiation ensures the filler remains firmly attached to the sliding material even during continuous operation under varying loads.

AI summary
Provided is a compressor including a sliding material with the wear resistance improved. To solve this problem, a compressor (40) includes: a compression chamber (43) that is formed in a cylinder (41) and compresses gas; and a piston ring 421 and a rider ring 422 that are in contact with the inner wall of the cylinder 41 to form the compression chamber (43). Th piston ring 421 and rider ring 422 include: a resin member; and a metal particle that is located within the resin member and includes a surface layer containing an affinity portion having an affinity to the resin member.
