Effect of Rotation Speeds on Friction Coefficients of PPS Race-PTFE Retainer Hybrid Polymer Thrust Bearings under Dry Contact

Abstract

In the previous study on PPS race-PTFE retainer Hybrid polymer bearings, the relationship between thrust load, rotation speeds and wear loss under dry condition was investigated. It was found that the wear loss obviously changed under the thrust load ranging from 400N to 500N at the rotation speeds of 450rpm and 600rpm. The object of this study is to observe the friction coefficient at the rotation speeds ranging from 450rpm and 600N under thrust load of 400N. Rolling contact fatigue tests were performed and it was concluded that friction coefficient decreases with the rotation speeds.
