Effects of Temperature on Seizure in PEEK Composite Bearing and Guideline for Improvement of Seizure-resistance

研究了环温对聚醚醚酮复合材料轴承断裂行为的影响。为了防止卡扣和降低密封圈温度，还对轴承上油槽和密封圈空气冷却两种方法进行了试验。结果表明，环温对其俘获行为有很强的依赖性。当环温超过100℃时，摩擦系数逐渐增大。随后，在120 ~ 140℃发生剧烈的塑性变形。建议采用油槽冷却和空气冷却等方法降低环温。这些方法有望成为预防癫痫发作的新方法。

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.
