| Research Abstract |
The effects of ring temperature on the seizure behaviors in the PEEK composite bearing have been studied. In order to prevent the seizure and decrease the ring temperature, both methods of oil grooves on the bearing and air cooling of ring have been also tested. It was found that the seizure behavior was strongly dependent on the ring temperature. As the ring temperature exceeded about 100℃, the friction coefficient got increasing. Thereafter, seizure accompanying severe plastic deformation occurred at 120-140℃. It was suggested that the methods such as oil grooves and air cooling of ring could be effective to decrease the ring temperature. It may be expected that these methods would be established as new method for preventing seizure.
