Friction Coefficient during Five-Phased Start-Stop Tests of PEEK-PTFE Hybrid Radial Ball Bearings Reaching 50 c° under 487N at 600rpm in Air

Article Preview

Abstract:

Start-stop rolling contact fatigue tests of PEEK-PTFE hybrid radial bearings were carried out, to investigate the influence of start-stop heat cycle on the friction coefficient of PEEK-PTFE hybrid radial bearings. It was found in all start-stop tests, the temperature of sample side increased as the friction coefficient increased. RCF cycles to reach 50 °C of the third start-stop phase clearly increased from the second start-stop tests, and then kept constant value.
