摘    要:选择平面型推力滑动轴承为研究对象,通过对粗糙表面的数值模拟,基于雷诺方程,构建了考虑微观形貌时的平面型推力滑动轴承润滑性能的计算模型。运用Matlab软件编程,针对一个具体的算例,采用数值计算研究了轴承工作时推力环旋转一周过程中最大油膜压力、承载能力、最小油膜厚度等参数的变化规律,发现其润滑性能与表面形貌有关;研究了转速、表面粗糙度等因素对推力滑动轴承润滑性能的影响规律,绘制了在保持全油膜润滑状态下速度和承载能力、摩擦力矩之间的关系曲线,并对这些曲线进行了分析。

关 键 词:推力滑动轴承  微观形貌  润滑性能  数值模拟

Abstract:Based on the numerical simulation of the rough surfaces and Reynolds equation,the calculation model for planar thrust sliding bearing with considering microcosmic topography was established.By use of a specific example,the changes of the maximum oil film pressure,bearing capacity and minimum oil film thickness of the thrust bearing during rotating were numerically calculated by using Matlab programming.The results show that the lubricating performance of planar thrust sliding bearing is relative with its microscopic morphology.The influences of rotation speed and surface roughness on the lubrication performance of thrust sliding bearing were studied in detail.The curves of relations between rotation speed,bearing capacity and friction torque under the condition of full lubrication film were obtained,and these correlation curves were analyzed.
Keywords:planar thrust sliding bearing  microscopic morphology  lubricating performance  numerical simulation
