Effect of PTFE retainer on friction coefficient in polymer thrust bearings under dry contact

摘要：

　　Polyetheretherketone (PEEK) is a tough semi-crystalline thermoplastic polymer with excellent mechanical properties.While abilities of polyphenylenesulfide (PPS) are similar to PEEK,former material cost was lower than later.Polytetrafluoroethylene (PTFE) is well known because of its low friction coefficient and self lubrication ability.The objective of this study is to observe the friction coefficient of hybrid bearings,PTFE retainer sandwiched with PPS-races or PEEK-races.Rolling contact fatigue tests were performed and in situ friction forces wear measured.It is concluded that the PTFE retainer reduced friction coefficient.
