A Study on the Wear Characteristics of a Journal Bearing According to its Material in the Scroll Compressors
In this study,we investigated the tribological behaviour of two different journal bearing materials.One of these journal bearing content is Cu(90 wt.%)-Sn(10 wt.%) alloy and is widely used in the automotive industry.The other is Al bearing.This journal bearing content is Al-Sn-Si-Cu.Therefore,it is required to study on the lublicating characteristics of bearing according to different materials.In this study,compressor journal bearings made by respectively PTFE solid lubricant and AI alloy with superior load carrying capacity,rubbing and impact endurance,have gone through journal bearing test.Lubrication and abrasion characteristics were evaluated by analyzing the material characteristics of a bearing bush in a scroll compressor.Al alloy bearings had an effect of lowering the friction coefficient by 28% than Cu-Sn alloy bearings under high load condition.
