Forming process of bearing materials suitable for high-speed bearings

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 experiments, material performance of Babbitt which was manufactured in new craft was validated. Compared 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.
