摘要

为了改善摩擦副的润滑性能,研究了复合微观纹理对斜垫式推力轴承润滑性能的影响。基于考虑复合微观纹理的斜垫推力轴承结构模型,分析了复合微观纹理参数和斜垫参数对推力轴承润滑特性的影响。同时,建立了考虑粗糙度和湍流效应的倾斜垫复合微观纹理轴承理论模型,研究了考虑粗糙度和湍流效应的推力轴承性能。结果表明,复合微观纹理轴承的性能优于单一微观纹理轴承,倾斜垫轴承的性能优于平行垫轴承,圆形复合鱼形微观纹理倾斜垫轴承的性能最佳。最佳轴承支点位置靠近内径,最佳支点圆周倾角约为 27.5°。考虑到粗糙度和湍流效应,轴承的最大压力和承载能力得到提高,摩擦系数显著降低。

Performance analysis of tilting pad thrust bearing incorporating the surface roughness, texture and turbulence effect
In order to improve the lubrication performance of the friction pair, the effect of composite micro-texture on the lubrication performance of the tilting pad thrust bearing is studied. Based on the structural model of tilting pad thrust bearing considering composite micro-texture, the lubrication characteristics of thrust bearing with composite micro-texture parameters and tilting pad parameters are analyzed. At the same time, the theoretical model of tilting pad composite micro-texture bearing considering roughness and turbulence effect is established, and the performance of thrust bearing considering roughness and turbulence effect is studied. The results show that the performance of composite micro-textured bearings is better than that of single micro-textured bearings, the performance of tilting pad bearings is better than that of parallel pad bearings, and the performance of circular composite fish-shaped micro-textured tilting pad bearings is the best. The optimal bearing fulcrum position is near the inner diameter, and the optimal fulcrum circumferential inclination angle is about 27.5°. Considering the roughness and turbulence effect, the maximum pressure and bearing capacity of the bearing improves, and the friction coefficient significantly reduces.

期刊介绍: The Journal of Engineering Tribology publishes high-quality, peer-reviewed papers from academia and industry worldwide on the engineering science associated with tribology and its applications. "I am proud to say that I have been part of the tribology research community for almost 20 years. That community has always seemed to me to be highly active, progressive, and closely knit. The conferences are well attended and are characterised by a warmth and friendliness that transcends national boundaries. I see Part J as being an important part of that community, giving us an outlet to publish and promote our scholarly activities. I very much look forward to my term of office as editor of your Journal. I hope you will continue to submit papers, help out with reviewing, and most importantly to read and talk about the work you will find there." Professor Rob Dwyer-Joyce, Sheffield University, UK This journal is a member of the Committee on Publication Ethics (COPE).
