A study of wear mechanism of plain bearing under actual sliding environment

Abstract

Plain bearings of industrial equipment are damaged by the wear, and it is main causes in the failure phenomena. Thus, inhibition of wear is significant for preventing the failure of machinery, but there are two subjects. The first is to elucidate the wear progress mechanism and to grasp the wear phenomena and the sign before machinery breakdown. The second is to perceive the damage type of equipment and to give the sufficient performance against machinery failure for the bearing. To satisfy these subjects, new tribometer is required, which can reproduce the sliding condition of actual machines. In this study, the authors have developed new tribometer, and carried out three types wear tests. In the initial friction test, there were two wear modes. In seizure test, wear particle was generated as the load increased, and they were buried in the Al alloy bearing.
