摘要: 聚醚醚酮(PEEK)是一种高强度、耐热的工程塑料,但其接触疲劳基础数据的缺失制约了它在重载场合下的高可靠、长寿命服役。开展了喷油润滑下的PEEK滚子滚动接触疲劳试验与PEEK齿轮接触疲劳试验,绘制了接触疲劳S-N曲线。对比发现,PEEK滚子滚动接触疲劳极限比齿轮接触疲劳极限高14%,接触压力135 MPa下的滚子滚动接触疲劳寿命比齿轮接触疲劳寿命长58%,进而提出PEEK的滚子齿轮接触疲劳寿命转换公式。

Abstract: PEEK was a high-strength, heat-resistant engineering polymer, but the absence of basic data of PEEK contact fatigue restricted the reliable and long-life applications under heavy-duty conditions. PEEK rolling contact fatigue tests and gear contact fatigue tests under oil injection lubrication were conducted herein, and the S-N curves were obtained. It is found that the PEEK rolling contact fatigue limit is 14% higher than gear contact fatigue limit, and the rolling contact fatigue life of rollers under the contact pressure of 135 MPa is 58% higher than gear fatigue life. And then, the conversion formula of PEEK roller-gear contact fatigue life was further proposed.

Key words: polyether ether ketone(PEEK), gear, roller, contact fatigue, S-N curve
