摘要：
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. © 2024 Chinese Mechanical Engineering Society. All rights reserved.
