Abstract

Abstract: It was found that the surfaces of interlaced wettability could improve the effective lubrication film formation performance under micro-oil supply. Based on this, a lubrication model of finite length roller pairs was established. The influences of the parameters such as interlaced wettability and working condition on the functional surface in micro-oil supply were analyzed. The results show that under certain working conditions, the interval oil supply mode of trace lubricating oil may play a role in enhancing lubrication efficiency. Due to the existence state of alternating oil supply, the lubrication performance in contact zones is unstable. The effectiveness of lubrication enhancement is affected by hydrophilic/hydrophobic bandwidth of the functional surfaces and the entrainment speed.

Key words: line contact pair, micro-oil lubrication, function surface, oil supply

摘要： 实验发现亲/疏油交替供油的功能润湿表面能提高微量供油下有效润滑的成膜性能。基于此，建立了有限长滚子副润滑模型，分析了交替供油的亲/疏油带宽及工作参数对润滑性能的增强规律。研究发现，微量供油条件下可利用交替供油方式达到线接触副润滑增效的目的，但供油交替变换使接触区润滑性能不稳定，且润滑增效作用会受功能表面亲/疏油带宽和卷吸速度的影响。
