单个微油滴弹流润滑行为的试验研究
发布时间:2018-08-22 17:17
【摘要】:利用光干涉技术研究了微油滴通过弹流润滑接触区的润滑行为,考察了油滴大小、卷吸速度和载荷等因素的影响.结果表明微油滴在入口区域因挤压或毛细力效应发生表面积扩展,从而影响润滑膜的形成.油滴越大,挤压扩展直径越大,形成的膜厚越大.卷吸速度越高,入口处微油滴表面积扩展越不充分,仅接触区局部形成油膜,微油滴在接触表面挤压出凹坑穿过接触区.
[Abstract]:The lubrication behavior of micro-oil droplets passing through the contact zone of elastohydrodynamic lubrication (EHL) was studied by means of optical interferometry. The effects of oil droplet size, entrainment velocity and load on the lubrication behavior were investigated. The thicker the film is, the higher the entrainment velocity is, the more insufficient the expansion of the surface area of the micro-oil droplets at the entrance is. Only the oil film is formed locally in the contact area, and the micro-oil droplets are squeezed out of the contact surface and pass through the contact area.
