微量供油下的线接触副润滑增效分析OA北大核心CSTPCD

It was found that the surfaces of interlaced wettability could improve the effective lubri-cation 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.
