摘要/Abstract

摘要： 船舰燃机轴承服役环境苛刻，工作界面难以建立全膜润滑状态，局部粗糙峰接触发生磨损，而磨损又会通过影响表面形貌反作用于界面混合润滑状态，影响轴承摩擦学特性。目前，面向燃气轮机滚动轴承，开展考虑真实表面粗糙度的磨损与混合润滑状态耦合作用的研究仍然很少。因此，以燃气轮机涡轮端球轴承为对象，综合考虑接触界面磨损、弹性变形与实测机械表面粗糙度影响，建立滚动体与内滚道三维磨损区域下的润滑－接触数值分析模型，研究低速、重载及滑滚苛刻条件下轴承摩擦磨损特性。

Abstract: The service environment of Gas turbine bearing is harsh, the working interface is difficult to establish a full film lubrication state, local roughness peak contact and wear occur, which will affect the interface mixed lubrication state by the influence of surface morphology, and tribological characteristics of the bearing will be further affected At present, there are few studies on the coupling effect of wear and mixed lubrication state considering the real surface roughness for gas turbine rolling bearings. Therefore, in this paper, the turbine ball bearing is taken as a case, considering the contact interface wear, elastic deformation and the effect of measured mechanical surface roughness, the lubrication-contact numerical analysis model under the three-dimensional wear area between rolling body and inner raceway is established, and the wear characteristics of the bearing under different low speed, heavy load and slide-roll conditions are studied.

Key words: gas turbine bearing, mixed lubrication, wear prediction, real machined roughness
