针对高速工况下轴承巴氏合金耐温性能及机械性能偏低等问题，用公理设计理论研究了巴氏合金轴瓦成形新工艺。通过在锡基巴氏合金中添加微量 Cu 及对冷却速度的控制，改进了原有工艺。浇铸件的材料力学和摩擦磨损测试表明：使用新工艺后，巴氏合金材料的耐温性能、抗压缩性能和结合性能获得了增强，减摩抗磨性能得到了提高。在高速试验台上对新工艺轴承进行了初步试验考核，试验轴承运行平稳，各项指标满足高速工况的使用要求。

Aiming at the problem that low temperature resistance and low mechanical properties of the bearing Babbit under high-speed conditions,a new process was designed by the axiomatic design method.The new process improves the deficiencies of the original process by adding a small amount of Cu and controlling cooling rate.Through the mechanics of materials and the friction and wear ex-periments,material performance of Babbitt which was manufactured in new craft was validated.Com-pared with the original process,temperature performance,resistance to compression properties get enhanced and tribological performance has been improved,when Babbitt was manufactured in new crafts.High-speed bearing test rig preliminary assessment tests show that:tested bearing runs smoothly,the indicators meet the requirements.
