Outline of Final Research Achievements

Seizure behavior of PEEK bearing is strongly dependent on the surface temperature. In order to decrease the surface temperature, low temperature air-jet method using compressed air and the ring specimen with grooves on the side for increasing heat radiation have been tested. Seizure occurred in the normal test without cooling. When using these cooling methods, seizure didn’t occur and the low ring temperature was kept. Although the low temperature air-jet method kept lower temperature than that in the specimen with the grooves, the friction coefficient tended to fluctuate a little. Thus it was demonstrated that cooling the frictional surface was available for preventing the seizure of PEEK bearing.
