摘要：

The mixture powder of Ultra-high molecular weight polyethylene (UHMWPE) and graphite was blended into nitrile-butadiene rubber (NBR) to be modified to develop a new kind of compound water lubricated rubber bearing with cost-effective, low-friction performance. In order to study the tribological and vibration performance of the new material, a series of experiments were carried out on the test rig SSB-100. Friction coefficient and vibration characteristics under different working conditions: speed, specific pressure and temperature were acquired and analyzed by torque meter and MK Pulse. The mechanical physical performance of the compound rubber material SPB-N has reached the requirements of Chinese ship standard CB/T769-2008. The results showed that a better tribological performance of the new material met the U.S. military standard (MIL-DU-17901C (SH)). Stick-slip effect of the new material was induced with critical speed of 027 m/s, which showed excellent low-speed performance. Moreover, its friction coefficient reached a minimum value at the speed of 054 m/s. Local specific pressure of the new material was 0.7 MPa. The new composite rubber material was served as a kind of water-lubricated bearing material with excellent all-round performances. (C) 2015 Elsevier B.V. All rights reserved.
